St. Louis Work Zones for March 12 - 18

ST. LOUIS - Motorists should consider alternate routes and expect major delays as crews continue work on the I-70 Blanchette Missouri River Bridge. Crews will be working to shift two eastbound I-70 lanes of traffic onto the westbound bridge. By Monday, March 16, the westbound direction of the bridge will be reduced from five lanes to three lanes across the bridge until November 2020. At the same time, the eastbound travel will be reduced to four lanes across the bridge. The Fifth Street ramp to eastbound I-70 ramp and the eastbound I-70 to Fifth Street will be closed several times throughout the week as crews prepare for the traffic switch.
