Longer Traffic Delays at I-270, I-44 Construction Area

Missouri Department of Transportation (MoDOT) engineers noticed longer delays at the Interstate 270 and Interstate 44 interchange in South County since the I-270 bridge project began this summer.

Since Saturday, engineers noticed a doubling of travel times along the I-44 exit ramps to southbound I-270 during the evening commute.

• Travel times begin to lengthen at 4 p.m. 
• The longer commute times last until about 6 p.m.
• The delay from eastbound I-44 to southbound I-270 delay is about twice as long, to 8-10 minutes from 4 minutes.
• There is about a 15-minute delay, instead of 3-4 minutes, to get from westbound I-44 to southbound I-270.

MoDOT suggests drivers use Lindbergh Boulevard instead of the I-44 exit ramps to get onto I-270.

Motorists should exit from I-44 at Lindbergh Boulevard, head south to Gravois Road and then merge onto southbound I-270, said MoDOT South County Area Engineer Kristy Yates in a news release.

"This signed detour can help motorists avoid the work zones on southbound I-270 entirely," Yates said.

MoDOT expects crews will need about two months to complete work on southbound I-270 between I-44 and Gravois Road.
