According to ablogtophone, Interstate 80 or I -80 is an Interstate Highway in the US state of Illinois. The highway forms an east-west route through the north of the state, connecting the Mississippi River Quad City metropolitan area with the suburban area of Chicagoland on the Indiana border. Interstate 80 in Illinois is 263 kilometers long.
Travel directions
I-80 at I-180.
Quad Cities
Interstate 80 in Iowa forms the northern bypass of Davenport, one of the Quad Cities, two of which are in Iowa and two in Illinois. On the east side of the Quad Cities, I-80 branches south and crosses the Mississippi River via the Fred Schwengel Memorial Bridge, entering the state of Illinois. I-80 has 2×2 lanes here and forms the eastern bypass of the town of Moline. This also crosses the Rock River and crosses Interstate 88, which is the most direct route to Chicago. Southeast of Moline then follows a cloverleaf where I-80 turns into a TOTSO, through traffic has to turn off, while the main carriageway turns into theInterstate 74 to Peoria. After this, I-80 leaves the Quad Cities region.
Central Illinois
According to beautyphoon, I-80 then follows a 180-mile stretch across the fairly flat prairies of central Illinois. This is a rural route with 2×2 lanes. I-80 mainly passes through a number of small towns, such as Princeton, Peru and Ottawa. The landscape is flat and mainly consists of meadows. US 6 runs parallel to I-80 here. Just past Princeton there is an interchange with Interstate 180, a short spur to Hennepin. A little further east near Peru, a cloverleaf cloverleaf follows Interstate 39 to Bloomington and Rockford. I-80 runs parallel to the Illinois River in this area and crosses the Fox River at Ottawa.
Chicagoland
I-80 over the Des Plaines River at Joliet.
I-80 then travels 60 kilometers south of the Chicago metropolitan area, also known as Chicagoland. I-80 opens up the town of Joliet, which also has an interchange with Interstate 55 from St. Louis. In Joliet one also crosses the Des Plaines River. Despite urbanization, I-80 through Joliet only has 2×2 lanes. East of Joliet there is an interchange with Interstate 355, after which I-80 has 2×3 lanes. The highway leads through a whole series of small suburbs that form a continuous urban area.
One then crosses three interstates in quick succession, first Interstate 57, then traffic from busy Interstate 294 merges and soon after also traffic from Interstate 94. Thus, on the stretch through the Chicago area, there are three major feeders to I-80 heading east, namely I-355, I-294, and I-94. I-80 continues to widen here, too, with 2×4 lanes from I-294 and 2×5 lanes from I-94. This section is called the Kingery Expressway. At the suburb of Lansing, the border with the state of Indiana follows, after which Interstate 80 in Indiana continues towards South Bend and Cleveland.
History
Northern Illinois has traditionally been a relatively dense network of important east-west connections. I-80 was planned in the US 6 corridor, but traffic between the Chicago area and the Mississippi River also served US 34, US 30, US 52 and US 20.
Construction history
The first sections of I-80 began construction about 1958, a section west of Ottawa was the first to be constructed. The section called the Kingery Expressway between I-94 in Lansing and the Indiana border was opened in 1950 and widened between 2005 and 2007. This is the oldest part of the entirety of Interstate 80. In 1958, the dual numbering system opened with I-294, as part of the Tri-State Tollway, between Hazel Crest and Lansing. The part through the countryside was built in the early 1960s, and the part between Joliet and Hazel Crest opened in 1964. In 1966 the bridge over the Mississippi at Moline opened. The entire route was completed by 1968 at the latest, making I-80 the first toll-free Interstate Highway that was completely completed.
widening
In 2005-2007, I-80 between I-294 and the Indiana border was widened from 2×3 to 2×4 lanes, east of I-94 to 2×5 lanes. In or before the 1990s, I-80 between US 45 in Mokena and I-294 was widened from 2×2 to 2×3 lanes. On October 24, 2012, the widening of an eight-mile stretch between US 30 at New Lenox and US 45 at Mokena was completed. The highway has been widened from 2×2 to 2×3 lanes here, along the south side of the Chicago metropolitan area.
Between 2021 and 2027, a 26-kilometre stretch through Joliet has been widened to 2×3 lanes and has been completely redeveloped. The project was conducted between Ridge Road in Minooka and US 30 at New Lenox. The project cost $1.2 billion.
Congestion
To the west of Joliet, congestion is unusual, traffic volumes are relatively low here. Congestion is more common due to the southern fringe of the Chicago metropolitan area, especially the busy stretch east of I-294 where heavy freight traffic is concentrated on I-80.
