ST. LOUIS – Motorists should be aware that MoDOT will close Dunn Rd. near Old Halls Ferry Rd. and the westbound I-270 exit ramp at Old Halls Ferry Rd. beginning Monday, August 3rd at 9 a.m. Both will be closed for one month. Motorists are encouraged to use I-270 at New Halls Ferry Rd. to Netherton Dr. as the detour route. All detours will be marked.
The closures allow for improvement of the intersection at Dunn Rd. and Old Halls Ferry Rd. and construction of an additional lane both eastbound and westbound on I-270. The intersection improvements, Old Halls Ferry Rd. Bridge construction and the added highway lanes are part of the ongoing $278 million I-270 North Project.
The I-270 North Project runs from James S. McDonnell Blvd. to Bellefontaine Rd. It will update and replace aging pavement and bridges, better link communities, improve accessibility for both bicyclists and pedestrians, and enhance traffic operations and safety throughout the corridor.
Drivers are encouraged to visit the project website at http://www.i270north.org to learn more about planned detours and about the specifics of the project, including a project overview and graphic displays of planned construction. In addition, website visitors can leave comments or signup for on-going updates. The public 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.
