According to a2zdirectory, US 14 is a US Highway in the US state of Illinois. The road forms an east-west connection in the north of the state, primarily in the Chicago metropolitan area. The road is 112 kilometers long.

Travel directions

The eastern starting point of US 14 in Chicago.

US 14 in Wisconsin enters the state of Illinois at the hamlet of Big Foot from the capital Madison. The road here has one lane in each direction and initially heads south. From the large village of Harvard, the road curves southeast and is equally 2×2 lanes at the distant suburb of Woodstock. Only from Crystal Lake does the road have 2×2 or more lanes continuously and is an important underlying connection due to the lack of motorways in this area. Crystal Lake is the beginning of Chicago ‘s contiguous metropolitan area, although it is still about 75 kilometers to the center. The US 14 has many intersections and is not a fast route. At Cary one crosses the Fox River, a fairly wide but short tributary of the Illinois River. This area consists of a fragmented suburban area, traditionally an agricultural area with a mix of housing. The US 14 here is called the Northwest Highway and has 2×2 lanes with emergency lanes, but with at-grade intersections. Some connections are level -level, but the majority of the intersections are level-level, with or without a traffic light. One then passes through Palatine, one of the larger suburbs northwest of Chicago. Here’s a connection to Interstate 290, which handles traffic toward downtown Chicago. The area then becomes even more urban and the road has 4 lanes without a central reservation. There is a main railway line next to the road.

Then you pass through the suburb of Arlington Heights which has a small business center. Then follow the suburbs of Mount Prospect and Des Plaines. Des Plaines is a major subcenter in the Chicago metropolitan area and intersects several roads here, such as US 12 and US 45 that run together further south, and then Interstate 294 shortly after. You then enter an older suburban area, where the houses are smaller, are built closer together and there is also less greenery. In Morton Grove, the road turns south along Caldwell Avenue into the city of Chicago itself. In the north of the city one crosses Interstate 94. US 14 then proceeds east on Peterson Avenue as a four-lane highway. An intersection in Lincolnwood crosses US 41, which runs along the coast of Lake Michigan from downtown toward the northern lakeside suburbs. US 14 then terminates at the northern end of Lake Shore Drive, the interstate highway to downtown Chicago.


US 14 was created in 1926 but was not extended to Chicago from Winona, Minnesota until 1933. Over the years, the Chicago starting point has changed slightly. Since 1978, US 14 begins at its current point in Chicago. In 1958 and 1960, the parallel Interstate 90 in Illinois was opened, eliminating the throughput of US 14.

Traffic intensities

The US 14 is a fairly busy road for an underlying link. 6,200 vehicles cross the Wisconsin border every day, rising to 12,300 at Harvard and 24,800 vehicles along Crystal Lake. At the Fox River this is 33,600 vehicles per day, after which it temporarily drops to about 23,000 vehicles towards Palatine. In Des Plaines, 28,900 vehicles drive per day, and in the north of Chicago, 44,600 vehicles drive on the 2×2 section full of intersections. Some 37,500 vehicles continue to the end at Lake Shore Drive.

According to Allpubliclibraries, US 150 is a US Highway in the US state of Illinois. The road forms a diagonal east-west route southeast through the center of the state and runs from US 6 at Moline to the Indiana border at Vermillion. Most of the route runs directly parallel to Interstate 74.

Travel directions

US 150 begins at the Quad Cities Airport on US 6, south of the town of Moline. The road then heads south across the prairies, 60 kilometers to Galesburg, parallel to I-74. US 150 cuts through Galesburg as an urban arterial, then curves east, again paralleling I-74 to the city of Peoria, one of the larger cities in central Illinois. US 150 heads north and east from Peoria, crossing the Illinois River in 2×2 lanes.

The US 150 then heads east and after more than 60 kilometers reaches the city of Bloomington. This part of the route alternates between flat bare prairies and some forest areas. US 150 runs through Bloomington as an urban arterial and crosses Interstate 55. From Bloomington, US 150 travels 80 kilometers southeast across the prairies to Champaign, still parallel to I-74. Also in Champaign, US 150 runs through downtown and intersects with Interstate 57. From Champaign, US 150 heads east over the prairies for over 30 miles to Danville.

The final stretch of US 150 heads south from Danville, initially with 2×2 lanes, but soon with one lane in each direction. About 35 kilometers south of Danville, at the village of Chrisman, you cross the US 36. The US 150 then continues south for another 20 kilometers and turns east at Paris. State Route 1 continues south toward Bridgeport, but US 150 follows the last 15 miles to the Indiana border. US 150 in Indiana then continues to Terre Haute and Louisville.


US 150 was created in 1926, but then followed a route that was entirely in Indiana. In 1934, the route to Rock Island was extended. In 1977, the western starting point was changed to Moline, near Rock Island. US 150 has largely been replaced by Interstate 74 in Illinois. I-74 was constructed parallel to US 150 between 1958 and 1973, which largely dwarfed US 150’s through-going importance. Only between Danville and Terre Haute in Indiana does US 150 still have a through-interest.

McCluage Bridge in Peoria

In the town of Peoria, the McCluage Bridge spans the Illinois River. These are two spans side by side. The construction of the bridge started in 1939 but due to the Second World War it took until 1948 before the bridge was completed. A second span opened adjacent to it in 1982, after which traffic headed east over the 1948 bridge and westbound traffic over the 1982 bridge. Both bridges were visually similar steel cantilever bridges. The oldest span was replaced between 2019 and 2023. The new bridge is a steel arch bridge.

Traffic intensities

The traffic volumes on the section parallel to I-74 are generally low, usually between 2,000 and 3,000 vehicles per day, sometimes lower with just 1,000 vehicles. The section from Danville to Paris drops from 20,300 vehicles at Danville to 3,400 vehicles for Paris. 2,300 vehicles cross the Indiana border every day.
