The St. Joseph Valley Parkway is a freeway in the U.S. states of Indiana and Michigan, serving as a bypass route around Elkhart, Mishawaka, and South Bend in Indiana and Niles in Michigan. The freeway runs to the south and west of Elkhart and South Bend and Niles and consists of segments of U.S. Route 31 (US 31) and US 20; those two highway designations run concurrently at the southwestern rim of the South Bend metropolitan area. It continues north to run along the St. Joseph River valley.
The freeway was first built in Indiana in the 1960s, although plans in Michigan date back to the 1950s. Indiana completed its portion of the freeway in 1992, while Michigan opened its last segment in 2022.
The Parkway begins where US 20 expands to a divided highway southeast of Elkhart. To the east in Indiana the freeway feeds into an undivided segment of US 20 at County Road 17 (CR 17). From there it runs westward along the south sides of Elkhart and Mishawaka. South of South Bend, US 31 joins the Parkway, and then the Parkway turns northward along the west side of South Bend. Along this segment, US 20 turns back west and leaves the Parkway. The Parkway meets the Indiana Toll Road which carries I-80/I-90 before crossing the state line into Michigan. [1] West of Niles, the Parkway meets US 12 and continues northwesterly running west of Berrien Springs. From there it runs northward to end at I-94 east of Benton Harbor. [2]
The Indiana Department of Transportation (INDOT) and the Michigan Department of Transportation (MDOT) both maintain the sections of the St. Joseph Valley Parkway in their respective states. Additionally, both departments have listed their freeway segments as part of the National Highway System, a system of roads important to the nation's economy, defense, and mobility. [3] [4] The two departments conduct surveys to measure the traffic levels along their roadways. This measurement is expressed in terms of annual average daily traffic (AADT) which is a calculation of the traffic volume on a stretch of roadway for any average day of the year. INDOT's figures for 2007 showed that 30,753 vehicles used the freeway near its western end. The traffic volume drops to 19,914 vehicles near the Indiana Toll Road. [5] In Michigan, the levels drop as low as 7,402 vehicles near the Napier Road interchange. [6]
The "St. Joseph Valley Parkway" name was chosen by local chambers of commerce in the fall of 1992 as the result of a local contest held by a group of local businesses. The name was officially adopted by Michigan in 1993 (dedicated late 1995) and Indiana in 1995 (dedicated in mid-1995). [7] [8]
There had been a southern bypass of the South Bend and Elkhart areas planned since the 1930s. [9] The first section of the highway, started in 1958 as Bypass US 20 (BYP US 20), was completed between US 20 and Mayflower Road (at the time State Road 123) on September 19, 1963. [10] The freeway was extended to just past the SR 23 interchange in late Summer 1965, [11] then further east to US 31, that section opening on December 15, 1967. [12] The BYP US 20 designation was replaced by the US 31 designation in 1978. [13] The exit with the Indiana East–West Toll Road/I-80/I-90 was built beginning in 1979 in conjunction with the northern extension to Michigan. [9] Construction in the early 1990s extended the freeway in sections from US 31/Business US 31 (Bus. US 31) to its current end with US 20 at CR 17, with the portion from US 31/Bus. US 31 to SR 19 opening on December 11, 1991, [14] and the portion from there to CR 17 opening on October 9, 1992. [15] Ramps from Nimtz Parkway were opened November 3, 1997, [16] and the portion in Elkhart was also named the "Dean R. Mock Expressway" in March 2002. [17] [18]
A plan to relocate US 31 in Berrien County, Michigan, existed as early as 1952. [19] Planning to extend the South Bend Bypass northward into Michigan to I-96 (later I-196) began in 1962. [20] A report issued in 1970 detailed four routing corridors, spawning a lawsuit over how Berrien Springs would be bypassed. Construction was to begin in 1975, but the Michigan State Highways Department delayed construction plans in 1972, pushing the start to 1977. The first section, running from the state line north to US 12, was completed and dedicated August 10, 1979, [21] and opened to traffic by September 6 of that year. [22] From there, US 31 was routed east along US 12 to Bus. US 12 and north along Bus. US 12 to the former routing of US 31/US 33. [23] Final plans for the routing north to I-94 were approved in 1981. [24] The Niles bypass section was opened August 16, 1987, [25] bringing the freeway north to Walton Road northwest of Niles. Bus. US 31 was created along the former routing in Niles and Walton Road was rebuilt as a state trunkline connection between the northern end of the freeway and the former two-lane routing of US 31. [26] The Berrien Springs bypass section was opened in late 1992, [27] the southbound lanes opening on October 23 and the northbound on November 20. [28] As a cost-saving measure, this section was initially an expressway with crossroads, [29] and was converted to a freeway in stages through 1999. [30] Since then, MDOT built a 9.1-mile (14.6 km) freeway segment north to Napier Avenue that was opened on August 27, 2003 at a cost of $97 million (equivalent to $154 million in 2023 [31] ). [32] [33] A proposed spur westward to I-94 in the Stevensville area was never built. [20]
East of Benton Harbor, Michigan, the St. Joseph Valley Parkway extension was under study due to environmental, economical and historical site issues. One of the environmental concerns relates to the habitat of an endangered species, the Mitchell's satyr butterfly that has its habitat in the area of the freeway extension. [34] The 40-acre (16 ha) habitat is home to the second-largest population of the rare butterfly. [35] This freeway connection was originally approved in 1981 as part of a final environmental impact study that included the freeway built from Niles northward to Napier Avenue. [36] Since that approval, the butterfly was discovered in the Blue Creek Fen in the late 1980s, [37] and it was listed an endangered species in 1992. The listing stalled construction of the freeway north of Berrien Springs. [27] The US Fish and Wildlife Service (USFWS) issued an opinion two years later that the freeway project would jeopardize the species. [37] MDOT was given permission to modify the previously approved freeway to cross the Blue Creek on longer bridges; the USFWS also required that any construction be done from elevated platforms, [38] among other restrictions. [35] In the interim, MDOT proceeded with construction of the southern portion of the last freeway segment, completing the freeway northward from Berrien Springs to the Napier Avenue interchange in August 2003. [32]
A revised environmental impact study to account for the butterfly's habitat was approved in 2004. [37] The study compared the original proposal for this extension that involved connecting directly to I-196 at I-94 with a pair of alternate routes that involved connecting US 31 directly to BL I-94 at I-94 near Benton Harbor with auxiliary lanes to I-196. The recommendation was to use the PA-2 version of the alternative connection to avoid the Blue Creek Fen. [39] At the time the last freeway segment was opened in 2003, MDOT expected the remaining segment would not take much longer to complete, [34] but funding was not available for many years. [40] Construction of the extension was not included for this reason in subsequent MDOT five-year highway projects plans, although most of the design work and land acquisition was identified in 2013 as having been finished. [41] Funding for the project was listed in the 2017–21 plan draft released in July 2016, which split the remaining work into three phases. [42] [43] MDOT received a federal grant for the project in December 2018, [44] citing at that time a completion date of 2022 or 2023 for the project; [45] construction began in June 2020. [46] The ribbon cutting for this section occurred on September 26, 2022. [2] [47] The new routing to I-94 formally opened on November 9, 2022. [48] Until the freeway was completed, US 31 followed a stretch of Napier Avenue, which was upgraded in conjunction with the St. Joseph Valley Parkway opening to that point, westward to I-94. [49] This stretch of Napier remained state trunkline until 2023. [50] The St. Joseph Valley Parkway name was applied to the new freeway section. [51]

M-239 is a north–south state trunkline highway in Berrien County in the extreme southwestern corner of the US state of Michigan connecting State Road 39 (SR 39) in Indiana to Interstate 94 (I-94). The highway was designated in 1963, and it provided the only connection from the southern end of I-94 into Indiana until 1972.
Interstate 275 (I-275) is an auxiliary Interstate Highway in the US state of Michigan that acts as a western bypass of the Detroit metropolitan area. The Michigan Department of Transportation (MDOT) maintains the highway as part of the larger State Trunkline Highway System. The freeway runs through the western suburbs near Detroit Metropolitan Wayne County Airport, and crosses several rivers and rail lines in the area. The southern terminus is the interchange with I-75 near Newport, northeast of Monroe. MDOT considers the Interstate to run to an interchange with I-96, I-696 and M-5 on the Farmington Hills–Novi city line, running concurrently with I-96 for about five miles (8.0 km). This gives a total length of about 35.03 miles (56.38 km), which is backed up by official signage. According to the Federal Highway Administration (FHWA), the length is 29.97 miles (48.23 km) because that agency considers I-275 to end at the junction with I-96 and M-14 along the boundary between Livonia and Plymouth Township. All other map makers, like the American Automobile Association, Rand McNally and Google Maps follow MDOT's practice.
M-63 is a state trunkline highway in the US state of Michigan that runs from M-139 at Scottdale through the cities of Benton Harbor and St. Joseph to Interstate 196/US Highway 31 (I-196/US 31) at exit 7 just outside Hagar Shores. The trunkline runs through residential areas south of St. Joseph and through the central business districts of the twin cities. Further north, M-63 runs along the Lake Michigan shoreline.
US Highway 27 (US 27) is a part of the US Highway System that now runs from Miami, Florida, to Fort Wayne, Indiana. In the US state of Michigan, it was a north–south state trunkline highway that entered the state south of Kinderhook and ended south of Grayling. Its route consisted of a freeway concurrency with Interstate 69 (I-69) from the state line north to the Lansing area before it followed its own freeway facility northward to St. Johns. From there north to Ithaca, US 27 was an expressway before continuing as a freeway to a terminus south of Grayling.
US Highway 131 (US 131) is a north–south United States Highway, of which all but 0.64 of its 269.96 miles are within the state of Michigan. The highway starts in rural Indiana south of the state line as a state road connection to the Indiana Toll Road. As the road crosses into Michigan it becomes a state trunkline highway that connects to the metropolitan areas of Kalamazoo and Grand Rapids before continuing north to its terminus at Petoskey. US 131 runs as a freeway from south of Portage through to Manton in the north. Part of this freeway runs concurrently with Interstate 296 (I-296) as an unsigned designation through Grand Rapids. US 131 forms an important corridor along the western side of the Lower Peninsula of Michigan, running through rural farm and forest lands as well as urban cityscapes. Various names have been applied to the roadway over the years. The oldest, the Mackinaw Trail, originated from an Indian trail in the area while other names honored politicians. An attempt to dedicate the highway to poet James Whitcomb Riley failed to gain official support in Michigan.
Interstate 75 (I-75) is a part of the Interstate Highway System that runs north–south from Miami, Florida, to Sault Ste. Marie in the Upper Peninsula of the US state of Michigan. I-75 enters the state from Ohio in the south, north of Toledo, and runs generally northward through Detroit, Pontiac and Bay City, crosses the Mackinac Bridge, and ends at the Canadian border in Sault Ste. Marie. The freeway runs for approximately 396 miles (637 km) on both of Michigan's major peninsulas. The landscapes traversed by I-75 include Southern Michigan farmland, northern forests, suburban bedroom communities, and the urban core of Detroit. The freeway also uses three of the state's monumental bridges to cross major bodies of water. There are four auxiliary Interstates in the state related to I-75, as well as nine current or former business routes, with either Business Loop I-75 or Business Spur I-75 designations.
M-217, also known as Michiana Parkway, is a multi-lane state trunkline highway in the U.S. state of Michigan. The Michiana Parkway, which extends into Indiana, was constructed as a joint effort of the Michigan Department of Transportation (MDOT), the Cass County Road Commission and the Elkhart County Highway Department. Michigan's segment of the parkway is 1.563 miles (2.515 km) long continuing County Road 17 (CR 17) in Elkhart County north into the state.
M-139 is a state trunkline highway entirely within Berrien County in the US state of Michigan. The highway starts at US Highway 12 (US 12) southwest of Niles and runs through rural areas of the county to terminate at an intersection with Business Loop Interstate 94 in Benton Harbor. The highway runs parallel to the St. Joseph River, crossing the river several times as it follows a set of roads previously used for US 31 in the area. The highway was first designated in the 1930s as a bypass of the Benton Harbor and St. Joseph area. Its termini have been moved over the years since, extending and contracting the length of the highway between Niles and Benton Harbor. M-139 now serves to provide access through the area from a set of bypasses consisting of I-94 and US 31.
M-140 is a north–south state trunkline highway in Berrien and Van Buren counties of the US state of Michigan. The highway starts in the Niles area at M-139 and runs north through Watervliet to South Haven, ending at Interstate 196/US Highway 31 (I-196/US 31). In between, it runs through farm fields and past lakes in the southwestern part of the Lower Peninsula. The trunkline is used, on average, by between 1,500 and 10,200 vehicles.
Interstate 94 (I-94) is a part of the Interstate Highway System that runs from Billings, Montana, to the Lower Peninsula of the US state of Michigan. In Michigan, it is a state trunkline highway that enters the state south of New Buffalo and runs eastward through several metropolitan areas in the southern section of the state. The highway serves Benton Harbor–St. Joseph near Lake Michigan before turning inland toward Kalamazoo and Battle Creek on the west side of the peninsula. Heading farther east, I-94 passes through rural areas in the middle of the southern Lower Peninsula, crossing I-69 in the process. I-94 then runs through Jackson, Ann Arbor, and portions of Metro Detroit, connecting Michigan's largest city to its main airport. Past the east side of Detroit, the Interstate angles northeasterly through farmlands in The Thumb to Port Huron, where the designation terminates on the Blue Water Bridge at the Canada–United States border.
US Highway 12 (US 12) is an east–west United States Numbered Highway that runs from Aberdeen, Washington, to Detroit, Michigan. In Michigan, it runs for 210 miles (340 km) between New Buffalo and Detroit as a state trunkline highway and Pure Michigan Byway. On its western end, the highway is mostly a two-lane road that runs through the southern tier of counties roughly parallel to the Indiana state line. It forms part of the Niles Bypass, a four-lane expressway south of Niles in the southwestern part of the state, and it runs concurrently with the Interstate 94 (I-94) freeway around the south side of Ypsilanti in southeastern Michigan. In between Coldwater and the Ann Arbor area, the highway angles northeasterly and passes Michigan International Speedway. East of Ypsilanti, US 12 follows a divided highway routing on Michigan Avenue into Detroit, where it terminates at an intersection with Cass Avenue.
US Highway 31 (US 31) is a part of the United States Numbered Highway System that runs from Alabama to the Lower Peninsula of the US state of Michigan. In Michigan, it is a state trunkline highway that runs from the Indiana–Michigan state line at Bertrand Township north to its terminus at Interstate 75 (I-75) south of Mackinaw City. Along its 355.2-mile-long (571.6 km) route, US 31 follows the Michigan section of the St. Joseph Valley Parkway as well as other freeways and divided highways northward to Ludington. North of there, the trunkline is a rural undivided highway through the Northern Michigan tourist destinations of Traverse City and Petoskey before terminating south of Mackinaw City. Along its route, US 31 has been dedicated in memory of a few different organizations, and sections of it carry the Lake Michigan Circle Tour (LMCT) moniker. Four bridges used by the highway have been recognized for their historic character as well.
Interstate 69 (I-69) is a part of the Interstate Highway System that will eventually run from the Mexican border in Texas to the Canadian border at Port Huron, Michigan. In Michigan, it is a state trunkline highway that enters the state south of Coldwater and passes the cities of Lansing and Flint in the Lower Peninsula. A north–south freeway from the Indiana–Michigan border to the Lansing area, it changes direction to east–west after running concurrently with I-96. The freeway continues to Port Huron before terminating in the middle of the twin-span Blue Water Bridge while running concurrently with I-94 at the border. There are four related business loops for I-69 in the state, connecting the freeway to adjacent cities.
There are currently eight business routes of Interstate 94 (I-94) in the US state of Michigan. These business routes connect I-94 to the downtown business districts of neighboring cities. Seven of the eight routes are business loops which bear the Business Loop I-94 designation while one is a business spur that bears the Business Spur I-94. These loops are former routings of I-94's two predecessors in Michigan: US Highway 12 (US 12) or US 25. The westernmost BL I-94 runs through the twin cities of Benton Harbor and St. Joseph along the former routing of US 12 and US 31/US 33 that now includes a section of the Lake Michigan Circle Tour in the state. The loops in Kalamazoo, Battle Creek, Marshall, Albion, and Jackson were also formerly segments of US 12 which were later designated as separate version of Business US Highway 12 through their respective cities before becoming BL I-94s in 1960. The BL I-94 in Kalamazoo was converted into BS I-94 in 2019. The route of the business loop through Ann Arbor was previously US 12 and then later M-14 before receiving its current moniker. The BL I-94 through Port Huron was previously US 25 and then Business US Highway 25.
US Highway 127 (US 127) is a part of the United States Numbered Highway System that runs from Chattanooga, Tennessee, to the Lower Peninsula of Michigan. In Michigan, it is a state trunkline highway that runs for 212.2 miles (341.5 km), entering from Ohio south of Hudson and ending at a partial interchange with Interstate 75 (I-75) south of Grayling. US 127 is the primary route connecting Lansing and Central Michigan to Northern Michigan and the Mackinac Bridge. From the south side of Jackson northerly, it is mostly a four-lane freeway. A notable exception is a 16-mile (26 km) stretch from north of St. Johns to just south of Ithaca, where the highway is built as an expressway and speed limits are lower. South of Jackson to the state line, the trunkline is a two-lane, undivided highway with access from adjacent properties.
US Highway 33 (US 33) is a part of the United States Numbered Highway System that was once located in Berrien County, Michigan. At the time it was removed from the state, it was only about 2.8 miles (4.5 km) long running north from the Indiana state line to an intersection with US 12 south of Niles. The highway was not originally part of the US Highway System in the state; it was added in 1938 as a second designation for part of US 31 between the state line and St. Joseph. It was later extended further north to the community of Lake Michigan Beach. This extension became the only section of US 33 that was routed independent of another highway until it was truncated to Niles. In 1997, US 33 was officially removed from the state.
The State Trunkline Highway System consists of all the state highways in Michigan, including those designated as Interstate, United States Numbered, or State Trunkline highways. In their abbreviated format, these classifications are applied to highway numbers with an I-, US, or M- prefix, respectively. The system is maintained by the Michigan Department of Transportation (MDOT) and comprises 9,669 miles (15,561 km) of trunklines in all 83 counties of the state on both the Upper and Lower peninsulas, which are linked by the Mackinac Bridge. Components of the system range in scale from 10-lane urban freeways with local-express lanes to two-lane rural undivided highways to a non-motorized highway on Mackinac Island where cars are forbidden. The longest highway is nearly 400 miles (640 km) long, while the shortest is about three-quarters of a mile. Some roads are unsigned highways, lacking signage to indicate their maintenance by MDOT; these may be remnants of highways that are still under state control whose designations were decommissioned or roadway segments left over from realignment projects.
A-2 is a county-designated highway in the US state of Michigan running about 42 miles (68 km) along the shores of Lake Michigan in the southwestern part of the Lower Peninsula. The county highway starts near the town of Lake Michigan Beach in Berrien County at an intersection with M-63 and follows Blue Star Highway through rural coastal areas. Running roughly parallel to its modern freeway replacement, Interstate 196 (I-196), A-2 passes through the cities of South Haven and Saugatuck before ending at an interchange with Business Loop Interstate 196/US Highway 31 in Holland.
MDOT anticipates completing the project in 2022. It will be done by 2023 at the latest, [MDOT spokesman Nick Schirripa] said.
The portion of highway US 31 beginning at the Michigan–Indiana state line and extending north to the intersection with I-94 in Berrien County shall be known as the 'St. Joseph Valley Parkway'.
