Crews break ground on I-64 replacement bridge

CHESTERFIELD, Mo. -- Contractors broke ground Thursday on construction of a bridge that will carry Interstate 64 traffic across the Missouri River near St. Louis.

State and local dignitaries were on hand for the groundbreaking for the new Daniel Boone Bridge near Chesterfield, which is expected to be completed in late 2015 but which officials say will be open for traffic by the end of next year.

The $110.9-million bridge will replace a current one that was built in 1935.

Plans call for the existing eastbound span to switch to westbound traffic, with the new span to carry eastbound vehicles once it opens. The existing westbound structure then will be razed.

The new bridge will be a steel plate girder design with a 510-foot span to allow unimpeded shipping traffic.

Walsh Construction Co. of Chicago and J.S. Alberici Construction Co. of St. Louis are the project’s joint venture contractors.

The new span will have four 12-foot lanes, as well as shoulders on both sides and a bicycle path featuring pullout areas to observe the river. The existing span that will be knocked down has three 10-foot-wide lanes but no shoulders.
