September 3, 2020 — For immediate release

ST. LOUIS — Drivers who regularly use the Bellefontaine Rd. entrance ramp to westbound I-270 at Dunn Rd. should be aware of an upcoming closure beginning at 9 a.m. on Tuesday, September 8, 2020. The closure will remain in place for 2.5 months.

Westbound traffic will detour using northbound Dunn Rd. to the intersection with Benham Rd. and take southbound Route 367 to access westbound I-270. All detours will be marked.
The closure is part of an ongoing $278 million project along the I-270 North corridor.

"This closure is significant because it includes the first at-grade cross-over slip ramp removal, paving the way for a more modern and safer Interstate 270," said I-270 North Project Director Justin A. Wolf.

Drivers are encouraged to visit the I-270 North Project website at www.i270north.org to learn more about planned detours and details of the project, including a project overview and graphic displays of planned construction. Travelers can also contact MoDOT’s customer service center at 1-314-275-1500 or contact the I-270 North Project Team at: I270North@modot.mo.gov
