for the bridge. The request generated enormous controversy and ultimately of the Jefferson Expansion National Memorial was given to the bridge. The traffic was heavily congested until the opening of the new Stan Musial Veterans Memorial Bridge in early February 2014. In 2012, 123,564 vehicles used it every day, but after the new bridge opened, congestion alleviated by almost 14%, less than the predicted 20% decline with 106,500 vehicles using it every day because total traffic across the river from all bridges increased by 7.4% over 2013 levels.

Description

Two Interstates and a U.S. Highway cross the entire bridge. Approximately 100,000 vehicles cross the bridge daily, making it the second most heavily used bridge on the river, after the I-94 Dartmouth Bridge in Minneapolis, Minnesota. I-55, I-64 and U.S. Route 40 (US 40) cross the Mississippi on the Poplar Street Bridge. US 66 also ran concurrently over this bridge until 1979, and US 50 was routed over it before the Interstates were constructed. In addition, I-70 crossed the river here until 2014, when it was realigned to cross the river on the Stan Musial Veterans Memorial Bridge when it was completed. With both I-55 and I-64 routed alongside I-70 prior to its rerouting onto the new bridge, the Poplar Street Bridge was the site of just (then) two three-route concurrencies within the

and Madison. The old alignment of I-70 through downtown to the west approach for the Stan Musial Veterans Memorial Bridge became an extension of I-44. However, motorists traveling eastbound on I-44 must continue westbound on I-70 and do not have a direct connection to the Stan Musial Veterans Memorial Bridge, while motorists traveling westbound on I-70 do not have a direct connection to I-44 westbound. Such access requires using I-55/I-64 across the Poplar Street Bridge, Westbound I-70 traffic must follow I-55/I-64 before Exit 3 on the Illinois side of the river to connect to I-44 westbound on the Missouri side, while eastbound I-44 traffic must exit onto I-55/I-64 on the Missouri side to connect to I-70 eastbound the Illinois side.

Name

Although the bridge's former name honors former St. Louis mayor Bernard F. Dickmann, it is most commonly referred to as the Poplar Street Bridge, with many locals unaware of its official name. The Missouri end of the bridge sits over Poplar Street, and the media started referring to it by that name long before the bridge opened due to the fact that the bridge was built over Poplar Street. It was officially renamed as the Congressman William L. Clay Sr. Bridge in October 2013 in honor of Bill Clay.
