ST. LOUIS - Drivers heading into downtown on Interstate 70 this weekend may want to consider alternate routes as the Missouri Department of Transportation will close various lanes on the interstate this weekend.

Crews will be placing girders over the interstate as part of work to connect the future new Mississippi River Bridge to Cass Avenue. This work is weather permitting.

The following lanes and ramps will be closed:

• Express lanes: Crews will close the express lanes at 9 a.m. Friday, December 14. This will impact Friday evening's rush period through downtown. The express lanes will reopen by noon Sunday, December 16.
• Biddle Street ramp: Crews will close the Biddle Street ramp at 7 p.m. Friday, December 14. To detour around the closure, drivers can continue on Broadway to N. Market Street and use N. Market to access Interstate 70. The Biddle Street ramp reopens by 10 a.m. Saturday, December 15.
• I-70 through lanes: Crews will close up to two lanes on I-70 in both directions, starting at 7 p.m. Friday, December 14. All I-70 lanes may be closed for up to 15 minutes at a time as crews swing girders over the interstate and connect them. All I-70 lanes, except the express lanes, will reopen by 10 a.m. Saturday, December 15.

Friday evening rush period drivers heading into the city may want to consider other routes due to potential congestion on eastbound I-70. Overnight Friday, drivers should allow themselves extra time to get to their destinations, or take alternate routes. 

              In addition, the planned reopening for the ramp from westbound I-70 to Madison has been delayed until late January so crews can complete some additional utility work.
