According to foodezine, State Route 255 is a state route and freeway in the U.S. state of Illinois. The highway is located in the “Metro East” region of St. Louis and connects Alton to the highway network. State Route 255 is 38 kilometers long.

Travel directions

State Route 255 is a continuation of Interstate 255, St. Louis ‘ eastern bypass. The highway intersects Interstate 270 and heads north with 2×2 lanes. The highway is actually a major bypass of the city of Alton, passing through the edge of built-up areas, with quite a bit of forest, particularly on the northern two-thirds of the route. There are also some low hills. After Godfrey, SR-255 becomes US 67, which heads north to Jacksonville.


Plans for a highway connecting Alton to the highways around St. Louis were first made in the late 1970s. Alton is not a suburb, but traditionally an independent city, just north of St. Louis on the Mississippi River. In the early years, a bypass from Alton had little priority. It was not until the second half of the 1980s that serious plans began to be made for an extension of I-255. The first section opened to traffic in 1998, but most of the highway opened to traffic in 2006-2013.

State Route 255 may become part of Interstate 255 in the future. In that case, the exit numbers should be adjusted.

According to bittranslators, State Route 390, formerly known as the Elgin-O’Hare Expressway and today as the Elgin–O’Hare Tollway, is a state route and toll road in the US state of Illinois. The interstate is a suburban route that connects several suburbs in western Chicago. Contrary to the name, the highway does not run into Elgin nor O’Hare Airport. The route is 18 kilometers long.

Travel directions

State Route 390 at I-290.

The highway begins at a junction with US 20 in Hanover Park, a suburb on the west side of the Chicago area. The highway initially has 2×2 lanes, but soon 2×3 lanes and runs east through suburban areas. In the Itasca suburb is a major interchange with Interstate 290. The highway then runs over industrial estates and ends on the west side of the O’Hare International Airport on York Road, in the suburb of Bensenville.


The Elgin – O’Hare Expressway opened on November 2, 1993 to relieve local roads in the fast-growing suburbs. The original highway ran from US 20 in Hanover Park to State Route 53 in Itasca. On October 29, 2013, the route was renumbered as State Route 390. Before that, the Elgin – O’Hare Expressway had no number. It was one of the very few highways in the United States without a road number.

As part of the new Interstate 490 along the west side of O’Hare Airport, the original Elgin-O’Hare Expressway has been extended eastward to future I-490. Construction began on October 29, 2013. In early 2015, the grade-separated intersection with Rohlwing Road (SR-53) opened. On July 27, 2015, the first flyovers opened at the interchange with I-290. Also in 2015, the section of the old Elgin-O’Hare Expressway between Irving Park Road and Rohlwing Road (SR-53) was widened to 2×3 lanes over a distance of 7 kilometers.

The interchange with Interstate 290 was completed in 2017, and on November 1, 2017, the 6-kilometer extension eastwards from I-290 to IL-83 opened. This completed the extension of State Route 390.

Since July 5, 2016, the highway is a toll road. The extension opened in 2017 is also a toll road. The toll is fully electronic with I-Pass. State Route 390 has the signature long lane marking found on other toll roads around Chicago.

Traffic intensities

Every day, 87,000 vehicles drive on the western portion of State Route 390.

Wacker Drive

Wacker Drive is a city highway in Chicago, Illinois. The road forms a half ring road around the center, and consists of two different levels. The main part is a double-decker city road, and is 3.5 kilometers long.

Travel directions

Wacker Drive consists of two decks, the Lower Wacker Drive and the Upper Wacker Drive. The double-decker road runs along the Chicago River around the Chicago Loop, the center of the city. Wacker Drive begins at Harrison Street, located near the terminus of Interstate 290. The road then runs north for 1.5 kilometers, then east for 2 kilometers, ending at Lake Shore Drive.

Wacker Drive is home to numerous skyscrapers, including some towers over 200 meters high, including the 442-meter-tall Willis Tower (formerly Sears Tower). Although Wacker Drive is double deck, it is not a highway. There are traffic lights and pedestrian crossings on both levels. The speed limit on Wacker Drive is 30 mph (50 km/h).


The plan for a double-deck road along the Chicago River was made as early as 1909. At the time, Chicago was one of the largest cities in the world with 2 million inhabitants. The first section of the double-deck road was completed in 1926, the east-west section between Lake Street and Michigan Avenue. Between 1948 and 1954, a southward extension was constructed to Congress Parkway and Harrison Street. An extension was built eastward to Lake Shore Drive in 1963 and 1975.

The original 1926 section, as well as a connecting section south of it to Randolph Street, was renovated between 2001 and 2002, with the double-deck section completely replaced from Randolph Street to Michigan Street. The renovation cost $200 million. Between 2010 and 2013, the southern part of Wacker Drive was modernized.
