ST. LOUIS – Drivers who regularly use New Florissant Road (Route N) near I-270 should be aware of weekend closures starting Friday, February 11. The Missouri Department of Transportation (MoDOT) will close New Florissant Road in both directions at I-270, reduce eastbound and westbound I-270 traffic to one lane over Route N, and close the entrance ramp from Hanley Road to eastbound I-270 beginning at 9 p.m. on Friday, February 11.
The lane closures will safely allow the partial demolition of the existing I-270 bridge over New Florissant Road and prepare for work on building the new I-270 bridge over New Florissant Road.
Drivers should anticipate major delays on I-270 in North St. Louis County on Saturday, February 12 and Sunday, February 13. MoDOT anticipates all lanes reopening by 5 a.m. Monday, February 14. All work is weather permitting.
Detours for New Florissant Road are as follows:
Southbound traffic will bypass construction by traveling west on Dunn Road to travel south on Hanley Avenue/Graham Road, to travel east on Pershall Road back to New Florissant Road
Northbound traffic will bypass construction by taking Pershall Road east to Washington Street/Elizabeth Avenue, to travel north on Washington Street/Elizabeth Avenue, to travel west on Dunn Road back to New Florissant Road
