I-474 begins on the west side of Peoria at an interchange with Interstate 74. In its extension is State Route 6, which forms the city’s northern bypass as a freeway. The highway heads south first, past Peoria Airport, followed by a truss bridge over the Illinois River, before I-474 veers east. Southeast of Peoria, I-474 then terminates at I-74.

History

After I-74 was opened by Peoria in the mid-1960s, it was considered necessary to build a bypass, although it is of little importance for through traffic. However, the airport of Peoria is located on I-474. The bridge over the Illinois River opened to traffic in 1975, but the rest of the route was built later, in the late 1970s, but at least after 1977. The highway was completed on December 20, 1979.

Later, plans were made for a complete ring road of Peoria, also called the Eastern Bypass. The northern part of this opened on November 3, 1985 as State Route 6. In 2008, a planning study for the construction of an eastern bypass was launched, resulting in 20 variants that were refined to 4 variants by 2012. It was planned in 2014 to determine a definitive alternative, but the planning was subsequently discontinued.

Traffic intensities

Usually 28,000 to 32,000 vehicles use I-474 every day, except for the easternmost section, which has 17,000 vehicles.

Travel directions

I-64 in East St. Louis.

I-64 near Fairfield.

The highway begins at the Poplar Street Bridge, the bridge over the Mississippi River, over which Interstate 55 runs. One then comes through the faded glory of East St. Louis, a city that has lost two-thirds of its inhabitants since the 1960s. The city is rather run down, the road network is very poorly maintained, and there are some unfinished bridges and connections. Also, in many places 50% to 100% of the houses in some city blocks have been demolished, a phenomenon called urban prairie. At the derelict downtown, I-64 turns east, while I-55 continues to Chicago, joining I-70 from St. Louis and heading for Indianapolis. On the east side of East St. Louis one crosses theInterstate 255, the eastern bypass of St Louis.

After O’Fallon one leaves the conurbation, and one enters the prairies of southern Illinois. The area is then monotonous and flat. Occasionally one crosses a larger road, such as US 51, which runs from Carbondale to Decatur. At Mount Vernon, I-64 merges with Interstate 57, the highway from Memphis to Chicago. Both roads are then double-numbered for a few kilometers to the south side of Mount Vernon. Then I-64 continues east through the vast agricultural areas. At Mill Shoals you cross the US 45, the road from Harrisburg to Effingham. At Grayville one crosses the Wabash River, also the border with Indiana. Then Interstate 64 goes into Indianaon to Evansville and Louisville.

History

The Poplar Street Bridge over the Mississippi River was opened in 1967. On October 4, 1974, a 39-mile section from Nashville to I-57 at Mt. Vernon. In December 1973, a 23-mile (23-mile) section from New Baden to Nashville opened. On December 23, 1975, the last 39-kilometer stretch between East St. Louis and New Baden opened to traffic. On August 7, 1975, the eastern section between Mt. Vernon and Mill Shoals about 30 miles to traffic.

Widening

In 2007, I-64 between Caseyville and O’Fallon was widened to 2×3 lanes. This is in the eastern suburbs of St. Louis.

In 2012-2013, I-57/I-64 double-numbering at Mount Vernon was widened from 2×2 to 2×3 lanes. This project was completed in December 2013.
