Mobile Bay is a shallow inlet of the Gulf of Mexico, lying within the state of Alabama in the United States. Its mouth is formed by the Fort Morgan Peninsula on the eastern side and Dauphin Island, a barrier island on the western side. The Mobile River and Tensaw River empty into the northern end of the bay, making it an estuary. Several smaller rivers also empty into the bay: Dog River, Deer River, and Fowl River on the western side of the bay, and Fish River on the eastern side. Mobile Bay is the fourth largest estuary in the United States with a discharge of 62,000 cubic feet (1,800 m3) of water per second. Annually, and often several times during the summer months, the fish and crustaceans will swarm the shallow coastline and shore of the bay. This event, appropriately named a jubilee, draws a large crowd because of the abundance of fresh, easily caught seafood.
Interstate 4 (I-4) is an Interstate Highway located entirely within the U.S. state of Florida, maintained by the Florida Department of Transportation (FDOT).

E-ZPass is an electronic toll collection system used on toll roads, toll bridges, and toll tunnels in the Eastern United States, Midwestern United States, and Southern United States. The E-ZPass Interagency Group (IAG) consists of member agencies in several states, which use the same technology and allow travelers to use the same transponder on toll roads throughout the network. Since its creation in 1987, various independent systems that use the same technology have been folded into the E-ZPass system, including the I-PASS in Illinois and the NC Quick Pass in North Carolina. Negotiations are ongoing for nationwide interoperability in the United States.
U.S. Route 90 or U.S. Highway 90 is an east–west major United States highway in the Southern United States. Despite the "0" in its route number, US 90 never was a full coast-to-coast route. With the exception of a short-lived northward extension to US 62/US 180 near Pine Springs, Texas that existed for less than one year, its western terminus has always been at Van Horn, Texas; this is an intersection with Interstate 10 Business just north of an interchange with Interstate 10. Its eastern terminus is at Florida State Road A1A in Jacksonville Beach, Florida, three blocks from the Atlantic Ocean.
The Mobile River is located in southern Alabama in the United States. Formed out of the confluence of the Tombigbee and Alabama rivers, the approximately 45-mile-long (72 km) river drains an area of 44,000 square miles (110,000 km2) of Alabama, with a watershed extending into Mississippi, Georgia, and Tennessee. Its drainage basin is the fourth-largest of primary stream drainage basins entirely in the United States. The river has historically provided the principal navigational access for Alabama. Since construction of the Tennessee-Tombigbee Waterway, it also provides an alternative route into the Ohio River watershed.
Interstate 287 (I-287) is an auxiliary Interstate Highway in the US states of New Jersey and New York. It is a partial beltway around New York City, serving the northern half of New Jersey and the counties of Rockland and Westchester in New York. I-287, which is signed north–south in New Jersey and east–west in New York, follows a roughly horseshoe-shaped route from the New Jersey Turnpike (I-95) in Edison, New Jersey, clockwise to the New England Thruway (I-95) in Rye, New York, for 98.72 miles (158.87 km). Through New Jersey, I-287 runs west from its southern terminus in Edison through suburban areas. In Bridgewater Township, the freeway takes a more northeasterly course, paralleled by US Route 202 (US 202). The northernmost part of I-287 in New Jersey passes through mountainous surroundings. After crossing into New York at Suffern, I-287 turns east on the New York State Thruway (I-87) and runs through Rockland County. After crossing the Hudson River on the Tappan Zee Bridge, I-287 splits from I-87 near Tarrytown and continues east through Westchester County on the Cross-Westchester Expressway until it reaches the New England Thruway. Within New Jersey, I-287 is maintained by the New Jersey Department of Transportation (NJDOT), and, within New York, it is maintained by the New York State Thruway Authority (NYSTA).
A reversible lane is a lane in which traffic may travel in either direction, depending on certain conditions. Typically, it is meant to improve traffic flow during rush hours, by having overhead traffic lights and lighted street signs notify drivers which lanes are open or closed to driving or turning.
Interstate 565 (I-565) is a 22-mile-long (35 km) Interstate spur that connects I-65 in Decatur with U.S. Route 72 (US 72) in Huntsville in the US state of Alabama.
Interstate 78 (I-78) is an east–west route stretching from Union Township, Lebanon County, Pennsylvania, to New York City. In New Jersey, I-78 is called the Phillipsburg–Newark Expressway and the Newark Bay–Hudson County Extension of the New Jersey Turnpike. The highway runs for 67.83 miles (109.16 km) in the northern part of the state of New Jersey from the I-78 Toll Bridge over the Delaware River at the Pennsylvania state line in Phillipsburg, Warren County, east to the Holland Tunnel under the Hudson River at the New York state line in Jersey City, Hudson County. The Phillipsburg–Newark Expressway portion of I-78, formally called the Lightning Division Memorial Highway, runs from the Phillipsburg area east across rural areas of western New Jersey before entering suburban areas in Somerset County. The road crosses the Watchung Mountains, widening into a local–express lane configuration at Route 24 as it continues through urban areas to Newark. Here, I-78 intersects the mainline of the New Jersey Turnpike (I-95) and becomes the Newark Bay Extension, crossing the Newark Bay Bridge and continuing to Jersey City. The route, along with Route 139, follows a one-way pair of surface streets to the Holland Tunnel.
Memorial Parkway, also known as the Parkway, is a major thoroughfare in Huntsville, Alabama that carries over 100,000 vehicles on average a day. It, in whole or in part, follows U.S. Route 231, U.S. Route 431, U.S. Route 72, and State Route 53 through the Huntsville city limits. It is a limited access road through most of Huntsville city proper, providing exits to the frontage road which allows access to road intersections, as well as businesses and residences along the route. Both the limited access and frontage roads are referred to as Memorial Parkway. Originally constructed to bypass downtown Huntsville and officially opened on December 1, 1955, the highway is the major commercial thoroughfare through Huntsville, a status it has held since the mid-1960s.

Interstate 64 (I-64) in the US state of Virginia runs east–west through the middle of the state from West Virginia to the Hampton Roads region, for a total of 299 miles (481 km). It is notable for crossing the mouth of the harbor of Hampton Roads on the Hampton Roads Bridge–Tunnel (HRBT), the first bridge–tunnel to incorporate artificial islands, concurrent with U.S. Route 60 (US 60). Also noteworthy is a section through Rockfish Gap, a wind gap in the Blue Ridge Mountains, which was equipped with an innovative system of airport-style runway lighting embedded into the pavement to aid motorists during periods of poor visibility due to fog or other conditions.
The Mount Baker Tunnel or Mount Baker Ridge Tunnel carries Interstate 90 under the Mount Baker neighborhood of Seattle, Washington. It is actually a group of three tunnels that carry eight lanes of freeway traffic, plus a separate path for bicycles and pedestrians. The two originals are twin tunnel bores completed in 1940 and rehabilitated in 1993. The newest tunnel was built north of the original tunnels and opened in June 1989. The tunnel has a double-decked roadway with the bicycle/pedestrian path above the traffic lanes.
Interstate 10 (I-10) is a part of the Interstate Highway System that runs from Santa Monica, California, to Jacksonville, Florida. In Alabama, the Interstate Highway runs 66.269 miles (106.650 km) from the Mississippi state line near Grand Bay east to the Florida state line at the Perdido River. I-10 is the primary east–west highway of the Gulf Coast region of Alabama. The highway connects Mobile, the largest city in South Alabama, with Pascagoula, Mississippi, to the west and Pensacola, Florida, to the east. Within the state, the highway connects Mobile and Mobile County with the Baldwin County communities of Daphne and Fairhope. I-10 connects Mobile and Baldwin County by crossing the northern end of Mobile Bay and the southern end of the Mobile-Tensaw River Delta via the George Wallace Tunnel in Mobile and the Jubilee Parkway viaduct system between Mobile and Daphne.
Battleship Parkway, commonly referred to locally and in the media as the "Causeway", is a 7-mile (11.3 km) long causeway that carries US 90 and US 98 eastbound across Mobile Bay from the Bankhead Tunnel on Blakeley Island in Mobile, Alabama to Spanish Fort, Alabama. The roadway itself is a four-lane divided highway for most of its length. It is very susceptible to flooding and is usually submerged during hurricane storm surges. The Battleship Parkway is home to Battleship Memorial Park and to many of the Mobile area's more prominent seafood restaurants.
The General W.K. Wilson Jr. Bridge, more commonly known locally as the "Dolly Parton Bridge", consists of dual parallel tied through arches of weathering steel and beam viaducts of concrete that form one continuous span carrying four lanes of Interstate 65 across the Mobile-Tensaw River Delta northeast of the U.S. city of Mobile, Alabama. Built from 1978 to 1980, it spans a distance of 6.08 miles (10 km) over the delta, making it, along with the Jubilee Parkway across Mobile Bay to its south, among the longest bridges in the nation. It was named in honor of Walter K. Wilson, a Chief of Engineers with the United States Army Corps of Engineers and long-term resident of Mobile. He was credited with being one of the first people recognizing the need to construct a high-level bridge on Interstate 65 over the Mobile River that would not impede waterway development. The state of Alabama named the bridge in his honor after completion of construction in 1978.
Blakeley Island is an island in the U.S. state of Alabama, within the city limits of Mobile. Located on the northwestern coast of Mobile Bay, it is bounded on the west by the Mobile River, on the south by Pinto Island and Mobile Bay, and on the east and north by the Spanish River. Blakeley serves as a vital road connection point between the Bankhead Tunnel, George Wallace Tunnel, and Cochrane–Africatown USA Bridge on its east side and the Battleship Parkway and Jubilee Parkway on its west side. The northern end is largely undeveloped, while the southern end is dedicated to industrial uses, primarily petrochemical storage and shipbuilding. The largest complex is the shipyards of Austal USA. Approximately 1.25 miles (2.01 km) at its widest and 6 miles (9.7 km) at its longest, it has an average elevation of 7 feet (2.1 m). It, along with downtown, forms District Two of Mobile's city council districts.
