ST. LOUIS (KSDK) - The Missouri Department of Transportation has opened the new lane on northbound Interstate 270 from I-44 to Manchester Road.
The lane opened Wednesday afternoon.
The 3.5 mile section of interstate was widened by MoDOT from four lanes to five to improve congestion. This lane will allow for 20 percent more vehicles to travel through the section during morning rushes.
The lane will also increase the average speed of motorists from 30 miles per hour to 60 miles per hour during the rush.
Motorists are urged by MoDOT not to stop and merge when driving from I-44 to I-270.
Construction for an added southbound lane from Dougherty Ferry to I-44 will begin in the spring.
