ST. LOUIS – The Missouri Department of Transportation, and its contractor, Kozeny-Wagner, Inc., will close I-270 at Dougherty Ferry from Friday, June 1, 2007 to Monday, June 4, 2007 to tear down the Dougherty Ferry Bridge. Crews will begin restricting lanes on I-270 at 8 p.m. Friday; all lanes will be closed by 10 p.m. just before crews starting work to demolish the bridge and clean up the debris. Traffic will be routed over the entrance and exit ramps around the bridge, but drivers will not be able to access Dougherty Ferry Road. After the interstate reopens by 5 a.m. Monday, the ramps will close for the duration of reconstruction.
This $6.1 million project will widen the bridge from four lanes to seven lanes, including two through lanes and two left turn lanes on westbound Dougherty Ferry as well as one through lane and two left turn lanes on eastbound Dougherty Ferry. It will add an additional left turn lane from northbound I-270 to westbound Dougherty Ferry and an additional right turn lane from southbound I-270 to westbound Dougherty Ferry. Finally, the project will add an additional lane on westbound Dougherty Ferry between I-270 and Des Peres Road. The bridge and ramps are scheduled to re-open no later than September 1, 2007 — Labor Day weekend.
