Motorists who regularly use I-270 in north St. Louis County should be aware that the Missouri Department of Transportation will close the intersection of Dunn Rd. and Washington St. at 6 a.m. Monday, October 12 for three weeks.
The closure will allow the removal of the existing intersection pavement and rebuilding the intersection with new pavement to connect to the new Washington St./Elizabeth Ave. bridge over I-270.
New Florissant Rd. will serve as the primary detour route for travelers accessing Washington St. All detours will be marked.
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.
