ST. LOUIS – Drivers who regularly use New Florissant Road (Route N) near I-270 should be aware of night closures on Thursday, May 12 and Friday, May 13. The Missouri Department of Transportation (MoDOT) will close New Florissant Road in both directions at I-270 at 8:00 p.m. and reduce eastbound and westbound I-270 traffic to one lane over New Florissant Road at 9:00 p.m. each night. During the closures, crews will set girders for the new I-270 bridge over New Florissant Road. All lanes will reopen by 5:00 a.m. on Friday, May 13 and Saturday, May 14.
Detours for New Florissant Road are as follows:
Southbound traffic will bypass construction by traveling west on Dunn Road, south on Hanley Avenue/Graham Road and east on Pershall Road, back to New Florissant Road.
Northbound traffic will bypass construction by taking Pershall Road east to access the U-turn bridge near Washington Street/Elizabeth Avenue to travel west on Dunn Road back to New Florissant Road.
The closure and construction work are part of the $278 million I-270 North Project infrastructure upgrades.
