According to iTypeJob, US 40 is a US Highway in the US state of Illinois. The road forms an east-west route through the south of the state, from the Missouri border in East St. Louis along Interstate 70 to the Indiana border past Marshall. The route is 257 kilometers long.

Travel directions

US 40 in Missouri is double numbered from St. Louis with Interstate 55, Interstate 64 and Interstate 70. In East St. Louis, I-64 exits toward Louisville to the east and Interstate 255 crosses at Collinsville. At Troy, US 40 exits from I-55 and I-70 and then begins an individual route east, parallel to I-70. The distance from I-70 varies, but is usually no more than 2 kilometers. At Highland, US 40 rejoins I-70, continuing to Pocahontas, before continuing to Greenville, on the north side of I-70. In Greenville several state routes are crossed, after which the road leads to Vandalia, a small town where the US 51 crosses. US 40 then continues to follow I-70 over vast farmland to Effingham, the last larger town in Illinois. Effingham is a fairly important intersection, crossing a number of state routes here, but more importantly, Interstate 57 and US 45. After Effingham it is about 100 kilometers to the Indiana border. One crosses some regional state routes along the way and in Marshall one crosses State Route 1, the longest state route in the state. Not far after that one reaches the Indiana border. US 40 in Indiana then continues to follow I-70 through Terre Haute to Indianapolis.


US 40 was created in 1926, and has more or less followed its current route through Illinois ever since. The road followed a major through corridor, although it serves no major locations other than the suburbs of St. Louis, Illinois. In 1917, the MacArthur Bridge opened over the Mississippi River. In 1967 the replacement Poplar Street Bridge opened, over which US 40 along with I-55, I-64 and I-70 was routed. I-70 was mainly built parallel to US 40 during the 1960s. In 1973, I-70 was completed and US 40 had only a local function everywhere.

Traffic intensities

The Poplar Bridge over the Mississippi with I-55, I-64 and I-70 had 116,700 vehicles per day in 2007, dropping to 58,400 vehicles in East St. Louis, before peaking again for I-64 at 121,800 vehicles. At I-255 there are still 49,400 vehicles, and at Troy the US 40 cuts off the highways, and then has 12,000 vehicles along the suburb. The rest of the route is very quiet as the parallel I-70 handles most of the traffic, and the US 40 has only 1,000 vehicles per day, sometimes a bit more with 2,000 to 3,000 vehicles.

According to itypeusa, US 41 is a US Highway in the US state of Illinois. The road forms a north-south route through the northeast of the state, along the shore of Lake Michigan through the metropolitan area and city of Chicago. The road is partially a freeway, most notably Lake Shore Drive. The route is 104 kilometers long.

Travel directions

Lake Shore Drive in northern Chicago.

US 41 in Indiana enters the state of Illinois from the town of Hammond, under the Chicago Skyway ( I-90 ). The road passes through densely populated southern Chicago neighborhoods, and in the South Chicago neighborhood, US 12 and US 20 turn west toward the western suburbs. US 41 runs on the underlying road network, switching streets a few times before reaching Shore Drive, which runs through the entire city along Lake Michigan. The road then runs through a park with 2+3 lanes and then becomes a substandard 2×3 highway with no emergency lanes. From Kenwood the road widens to 2×4 lanes, although it is not a through highway. On the south side of downtown Chicago, the Stevenson Expressway ( I-55 ) terminates at US 41.

While downtown, US 41 is not a freeway, but becomes Lake Shore Drive on its north side. This 2×3 highway is wedged between countless skyscrapers and Lake Michigan. US 41 enters north of downtown through Lincoln Park and the highway ends on the north side of Chicago, which is also the terminus of US 14. US 41 then continues via Lincoln Avenue to the suburb of Skokie. US 41 then heads north on Skokie Boulevard and merges into Interstate 94 in the suburb of Wilmette. One then comes through the very prosperous suburbs north of the city. In Highland Park, I-94 turns west and becomes a toll road. US 41 continues straight as the Skokie Highway and is a 2×2 lane highway for a few more miles, before becoming a single-level urban arterial. The Skokie Highway is the main underlying link in this area, handling a lot of traffic. One crosses several east-west axes, mostly state routes. You pass Waukegan, Chicago’s most important northern suburb with more than 90,000 inhabitants. Just before the Wisconsin border, US 41 rejoins Interstate 94. US 41 in Wisconsin then continues over Interstate 94 in Wisconsin towards Milwaukee.


US 41 was created in 1926. It is the only north-south route that passes through Chicago. In 1937, the first section of Lake Shore Drive opened in downtown Chicago, at the time little more than a bridge over the Chicago River and a railroad overpass. During the 1950’s, Lake Shore Drive was extended northward through Chicago as an expressway. The road was reconstructed in the 1980s. The portion of US 41 that is double-numbered with the Edens Expressway (I-94) opened to traffic in 1951.

Traffic intensities

US 41 in northern Chicago.

US 41 is a busy road, mainly due to the fact that the city of Chicago itself has relatively few freeways, so traffic is strongly concentrated on the existing main routes. In the south of Chicago there are about 13,000 vehicles, which increases towards the center to 123,800 vehicles per day. 157,100 vehicles drive on the ground floor area along the center, and on the north side of the center there is a peak at 164,900 vehicles per day. The ground floor section in the north of the city has between 20,000 and 30,000 vehicles per day, with 26,000 vehicles in Skokie. The double numbering with the I-94 from Wilmette has a maximum of 158,100 vehicles per day, the section through Highland Park 77,000 vehicles. Heading north, toward Waukegan, the road continues at 45. 000 vehicles on the ground floor 2×2 section very busy. 23,400 vehicles continue to I-94 just before the border withWisconsin and 88,100 cross the border into Wisconsin daily.
