ST. LOUIS – Drivers who regularly use the eastbound I-270 exit ramp to New Florissant Road should be aware that the Missouri Department of Transportation (MoDOT) will close the ramp beginning at 7 a.m. Tuesday, September 6, weather permitting. The closure will last 45 days.
Crews will build a new eastbound exit ramp near New Florissant Road and create a new alignment of Pershall Road. In the new alignment, eastbound I-270 traffic will exit onto Pershall Road and Pershall Road will then intersect with New Florissant Road. In order to build and connect the new alignments, the exit ramp from eastbound I-270 must be closed and removed.
During the closure, signed detours will direct eastbound I-270 traffic to exit at Hanley Road and continue on Pershall Road to reach New Florissant Road. Drivers can also exit at Washington Street/Elizabeth Avenue and take the U-turn bridge to Dunn Road to travel to New Florissant Road.
The closure and construction work are part of the $278 million I-270 North Project infrastructure upgrades. To stay updated on the status of this closure and to view a project overview and graphic displays of planned construction, please visit the I-270 North Project website at: www.i270north.org. Travelers can also contact MoDOT’s customer service center at 1-314-275-1500 or the I-270 North Project Team at: I270North@modot.mo.gov.
