Travel directions

I-55/70 at Collinsville.

St. Louis

Interstate 70 in Missouri crosses the Mississippi River via the Stan Musial Veterans Memorial Bridge and then comes from St. Louis in East St. Louis, a run-down suburb. In East St. Louis, I-70 connects to Interstate 64. Traffic on I-70 then turns northeast. At Collinsville, one crosses Interstate 255, which together with Interstate 270 forms a ring road around the metropolitan area of ​​St. Louis. At the village of Troy, a second interchange follows, where Interstate 55 continues straight toward Springfield and Chicago, while I-70 exits east toward Indianapolis. Go west on Interstate 270.

Central Illinois

I-70 then becomes a quiet country highway and heads east, with US 40 paralleling the route. There are no major towns on the route in Illinois, this part of the state is quite sparsely populated, unlike the vast Chicago metropolitan area in the northeast of the state. A small town on the route is Vandalia, where US 51 intersects, which runs from Carbondale in the south to Decatur in the north. The Illinois landscape is fairly flat with meadows and sometimes some woods. One then reaches Effingham, a small town where the road is double-numbered with Interstate 57, the highway from Memphis to Chicago.. The double numbering takes about 10 kilometers. The route then continues through the fields of central Illinois. The countryside of the Midwest is quite monotonous, where the variety must be sought in the form of the large cities through which one passes. The final exit before the Indiana border is Dennison, after which Interstate 70 continues in Indiana to the city of Indianapolis.

History

Before the construction of I-70, US 40 was the through route from St. Louis to Indianapolis. Unlike neighboring Indiana, US 40 in Illinois has not been significantly upgraded outside the cities for the construction of I-70. The US 40 is single lane almost everywhere. On most of the route, I-70 is located no more than 2 or 3 kilometers from US 40, except between Troy and Highland.

During the construction of I-70, through traffic was immediately taken into account. I-70 branches off through downtown St. Louis, while Interstate 270 forms a northbound bypass of the St. Louis region, being the shortest route for through traffic on I-70.

On November 9, 1967, the Poplar Street Bridge over the Mississippi River opened to traffic, as did the first few miles of I-70 through East St. Louis. By 1973, the entire I-70 was ready.

In 1968 the following routes were completed:

  • East St. Louis – Pocahontas (55 km)
  • Greenville – Montrose (97 km)

East St. Louis

On February 9, 2014, the Stan Musial Veterans Memorial Bridge on the Missouri border opened to traffic. As a result, I-70 has been diverted over a more northerly route and has since been connected to the old route at I-64. The I-70 is therefore no longer double-numbered with the I-55 southwest of the I-64. However, the length of I-70 in Illinois remained virtually unchanged.

widening

In 2012-2013, I-57/I-70 along Effingham was widened to 2×3 lanes.

Congestion

The busiest part of I-70 is on the eastern side of the metropolitan area of ​​St. Louis, especially around East St. Louis, but traffic congestion is generally quite limited. East of the double-numbering with I-55, the intensities are quite low for an important interurban connection, with largely less than 25,000 vehicles per day. Traffic jams are a rarity here.

The Shawneetown Bridge is a truss bridge in the United States, located on the border of Illinois and Kentucky. The bridge spans the Ohio River at Shawneetown.

Characteristics

The bridge is a steel truss bridge with a total length of 975 meters and has two main spans of 251 meters in length. The bridge is 7.2 meters wide and has two lanes. Over the bridge runs State Route 13 in Illinois to Shawneetown and Harrisburg and State Route 56 in Kentucky to Morganfield. The bridge is toll-free.

History

The bridge was built in the mid-1950s and opened to traffic on June 1, 1956. At the time, it was the third bridge over the Ohio River between the states of Illinois and Kentucky and is also the easternmost bridge across the river between the two states. The bridge was built for regional traffic, which is mainly oriented east-west. The bridge is a bit further from the larger cities and is therefore not used intensively. The bridge deck was replaced in 2015.

Traffic intensities

2,600 vehicles use the bridge daily, making it the lightest bridge between Illinois and Kentucky.
