Crews will replace the driving surface with a new structural overlay on the bridges over the intersections of New Florissant Road and New Halls Ferry Road. This work will take one month to complete.
The bridges are more than 50 years old and are classified as structurally deficient. This is not a permanent fix, however, this work will extend the usable life of the bridges until funding becomes available for full bridge replacements.
Drivers can expect to see the following impacts, weather permitting:
Tuesday, July 7, Pershall Road (the one-way outer road from New Halls Ferry Road to the Home Depot entrance) will close at 7 p.m.
Wednesday, July 8, Eastbound I-270 on and off ramps at New Florissant Road will close at 8 p.m.
Wednesday, July 8, New Florissant Road under I-270 from Dunn Road to Jean Drive will close at 11 p.m.
Thursday, July 9, Eastbound I-270 off ramp to New Halls Ferry will close at 8 p.m.
Thursday, July 9, New Halls Ferry Road under I-270 from Dunn Road to Pershall Road will close 11 p.m.
Friday, July 10, Eastbound I-270 lanes will be reduced to two through lanes and routed down and back up the interchange ramps at New Florissant Road and New Halls Ferry Road after 8 p.m.
Saturday, July 11, Westbound I-270 lanes will shift onto eastbound bridge at New Florissant Road and New Halls Ferry Road after 8 p.m.
I-270 will remain open during construction. New Florissant Road and New Halls Ferry Road will be closed under I-270. There will be no access to or from eastbound I-270 at these locations.
Motorists will need to use alternate streets to cross I-270 while New Florissant Road and New Halls Ferry Road are closed. They will need to use adjacent interchanges to access I-270 while these interchanges are closed.
Monday, July 13 all closures will be in place and motorists should expect substantial backups on I-270 during construction. It is anticipated that average delays through the work zones could add 30 minutes or more to the daily commute. Motorists are encouraged to seek alternate routes to avoid this area during peak travel times.
