ST. LOUIS - The Missouri Department of Transportation will close all lanes of Interstate 64 in two places in the Chesterfield Valley area starting at 8 p.m. Friday, April 4.
Crews will be removing the Chesterfield Parkway West bridge and the old Chesterfield Airport Road bridge over the interstate.
All lanes are scheduled to reopen by 5 a.m. Monday, April 7.
Although both detours are relatively short, when taken in combination, motorists heading into or out of St. Charles County should consider other options - using I-270 and I-70, for instance. Although drivers will be able to detour around the work, traffic through the Chesterfield Valley is expected to be exceptionally congested this weekend.
"There are several events downtown that folks in the Chesterfield Valley area may be considering attending this weekend, such as the Go! Marathon. We would recommend that they avoid using I-64 and use other routes to get to Route 340 (Clarkson/Olive) or Route 141. They can then use those roads to get to I-64 and continue east," said Michelle Vogele, MoDOT Southwest St. Louis County area engineer.
The Chesterfield Parkway bridge will close on April 1. Chesterfield Parkway will be closed between Wild Horse Creek Road and Swingley Ridge starting at 8 p.m. Friday, April 4. In addition, the ramp from Route 340 to westbound I-64 will be closed at 8 p.m. Friday, April 4. This will ensure interstate traffic is able to travel smoothly through the detour route.
Detours for the Chesterfield Parkway West bridge closure are:
- Eastbound I-64 - use Exit 19A (Chesterfield Parkway) and take a left onto Wild Horse Creek Road. Follow the road and take the ramp back onto eastbound I-64.
- Westbound I-64 - Use Exit 19A (Chesterfield Parkway West) and bear to the right. At Chesterfield Parkway, take the ramp back down to westbound I-64.
Removing the old Chesterfield Airport Road bridge is part of the project to construct a new Daniel Boone Bridge between St. Louis County and St. Charles County.
Detours for the Chesterfield Airport Road bridge closure are:
- Eastbound I-64 - Use Exit 14 (Chesterfield Airport Road). Take Chesterfield Airport Road to Spirit of St. Louis Boulevard and turn left. Follow the boulevard and take the ramp back to eastbound I-64.
- Westbound I-64 - Use Exit 14 (Spirit of St. Louis Boulevard) and take the roundabout. Follow the roundabout to the second leg and continue along the new north outer road for I-64. Take the ramp back onto westbound I-64.
