US169 enters Minnesota near Elmore as a two-lane, undivided highway, continuing as such through the majority of Blue Earth. Near the northern outskirts of the town, it expands to a four-lane, divided highway, subsequently crossing Interstate90 (I-90). Soon after, it reverts to its original two-lane size. Roughly five miles (8.0km) southwest of Mankato, US169 and State Highway60 (MN60) merge to a single expressway through Mankato. In North Mankato, MN60 moves from a concurrency with US169 to another one with US14.
In Mankato and North Mankato, US169 functions as an arterial highway, passing directly through the cities' downtown area. From Mankato north to Jackson Township, the route remains an expressway, except for the section passing through St. Peter, where US169 is the main street through town.
The 55 miles (89km) of US169 from St. Peter to I-494 in Bloomington is officially designated the John A. Johnson Memorial Highway. This includes the Bloomington Ferry Bridge between Shakopee and Bloomington. This designation is marked as Johnson Memorial Drive on some maps, but not marked as such on directional signs, nor commonly known by this name.
In the Twin Cities area, the route is constructed to freeway standards between MN41 in Jackson Township and 109th Avenue North in Brooklyn Park. The freeway between I-494 and I-694 was originally built by Hennepin County as County Road 18 (CR18). In 1988, CR18 was transferred to the state of Minnesota and became the new alignment for US169 in the Minneapolis area. In exchange, Hennepin County took over maintenance of two other highways that were formerly state routes. In the Minneapolis area, US169 is often congested, but the freeway passes close to residential neighborhoods in many locations, so any expansion of the freeway would disrupt housing stock in the surrounding area.
From 109th Avenue North to the Mississippi River, US169 remains an expressway until Anoka, where it becomes a street. It then joins US10 west to Elk River. Those highways diverge at Babcock Wayside on the Mississippi River.
North of the Twin Cities metropolitan area, US169 continues as an expressway to Mille Lacs Lake, an important resort area. The highway skirts the western shore of the lake. The 74 miles (119km) of US169 from Elk River to Garrison is officially designated the POW/MIA Memorial Highway. From Mille Lacs Lake, US169 continues northward to its junction with US2 at Grand Rapids. Starting in Aitkin, US169 and MN210 share eight miles (13km) of road. In Grand Rapids, US169 turns northeasterly to reach the cities of the Mesabi Iron Range.
At the eastern end of Grand Rapids, US169 becomes an expressway and remains such for eight miles (13km). An additional 1.5 miles (2.4km), from Taconite to CR7 was completed in 2016. It passes through the cities of Hibbing, Chisholm, and Mountain Iron before reaching US53 at the city of Virginia. This four-lane stretch of US169 is also known as the Highway 169 Cross Range Expressway, with the highway shifted south between Mountain Iron and Virginia to allow for expansion of the U.S. Steel Minntac iron ore mine. The northern terminus of US169 is at the city of Virginia.
MN169 begins immediately north of Virginia in Wuori Township and continues northeast for 49 miles (79km) to the cities of Tower, Ely, and Winton. MN169 is numbered as an extension of US169.
US169 is one of three Minnesota U.S. Numbered highways to carry the same number as an existing state marked highway within the state. The others being Highways US61 and US65.
Legally, the Minnesota section of US169 is defined as all or part of Routes5, 7, 383, 3, 18, and 35 in the Minnesota Statutes §§161.114(2) and 161.117(4).[3][4] The route is not marked with those numbers.
History
Exit numbers started appearing in Shakopee in 2016
US169 was extended into Minnesota c.1931.[2] The route in Minnesota was paved by 1940.[2]
Previously, US169 served as the northern terminus of US53 in Virginia. US169 then continued north into International Falls. Today, US53 serves as the terminus of US169 in Virginia.
US169, between the junction with MN60 (south of Mankato) and the Twin Cities, was upgraded to at least expressway status over several stages. The freeway section around Mankato and the adjoining expressway sections were completed in the early 1960s, along with bypasses of Le Sueur, Jordan and Belle Plaine.[2]
The US169 freeway bypass around Shakopee was built in the mid-1990s along a new alignment, which included the newly constructed Bloomington Ferry Bridge. Prior to this realignment, US169 crossed the Minnesota River from downtown Shakopee where it had been co-signed with MN101. North of the river crossing, US169 had previously been co-signed with what was then US212 (Flying Cloud Drive) through Eden Prairie until 1996.
A new US169 interchange with MN19, near Henderson, was completed in 2002.[2]
An expressway section of US169 through southern Hennepin County was converted to full freeway in 2006, with new interchanges constructed at Pioneer Trail and Anderson Lakes Parkway. At-grade intersections with traffic signals have been removed at the recently constructed I-494 interchange, which was previously a point of frequent congestion.
North of the Twin Cities, US169 has been upgraded to an expressway between Elk River and the southern end of Mille Lacs Lake, with bypasses of Princeton and Milaca built in the late 1980s.
The expressway section between Pengilly and the city of Virginia was built in the late 1970s and early 1980s.
In 2008, construction began on a new US169 interchange with CR81 and 85th Avenue North in Brooklyn Park. This interchange is also known as The Devil's Triangle, or simply as The Triangle, because of the major traffic congestion during rush hour, especially in the afternoon. Construction was completed on August 11, 2011.
During the flooding of September 2010, flood waters destroyed a 150-foot (46m) section of the northbound lanes of US169 between St. Peter and Le Sueur. Minnesota Department of Transportation (MnDOT) believes, "when the flood waters rose up it found a weak spot in the slope or the dirt bank and got under the grass and started mining under the pavement. Finally, it just sucked all the dirt out and the pavement just dropped into a hole."[citation needed] Traffic was detoured to the southbound lanes of US169 for a month, resulting in a temporary two-lane expressway, until the northbound section was repaired.
In November 2010, construction began on a completely redesigned US169 interchange at I-494, where three traffic signals had existed. The new interchange features six roundabouts, new flyover bridges, and two new bridges over I-494 that will carry West 78th Street and Washington Avenue. Major construction began in March 2011. Construction continued in early 2012 with the completion of reconstructing surrounding roads and remaining ramps. MnDOT completed the entire project in November 2012. The 2010 cost of the construction project was $140 million.[5][6]
In 2016, exit numbers have started appearing on the Shakopee portion of the freeway section in the Minneapolis-Saint Paul metro area.
Between 2022 and 2024, the section of US169 between US10 and 197th Avenue in Elk River was being rebuilt as a freeway, with four new interchanges and a replacement of the northbound bridge over US10.[7] In 2023, the cloverleaf interchange at Rockford Road in Plymouth was replaced with a folded-diamond interchange and a new, wider bridge to accommodate for both bicyclists and pedestrians.[8]
A study to convert US169 to a freeway between US10 in Elk River to 277th Avenue north of Zimmerman was completed in late 2009. A complete review of the project by MnDOT occurred in 2011. A complete construction schedule and timeline were released by MnDOT. Allocation of funds for the project was currently underway and the only thing holding back from starting the project. The project is expected to cost around $178 Million. In the meantime, the 14 miles (23km) between US10 in Elk River to 277th Avenue north of Zimmerman were resurfaced during the 2012 construction season. The construction began in May 2012.[9]
