St. Louis Work Zones October 26-November 1

ST. LOUIS – The Missouri Department of Transportation (MoDOT) will open the new fly-over ramp from eastbound I-270 to northbound Route 367 on Friday, October 27 at 1 p.m. This critical opening moves MoDOT closer to its December 2023 completion of the $278 million I-270 North Project. 

“Opening this new ramp is a huge milestone for us as it is the last new feature of the project, and it eliminates the weaving pattern and traffic merge that previously occurred as drivers exited the loop ramp,” said Niall Jansson, I-270 North project director. “This opening, like every element of the project, helps improve both efficiency and safety throughout the entire I-270 North Corridor.”
