The driving lanes of the second half of Route 364/Page Phase 3 will open to traffic late in the weekend of October 31. The opening of the lanes between Route K and Mid Rivers Mall Drive marks one of the final key pieces of a regional transportation vision that began more than 40-years ago when a grassroots group was formed in St. Charles County to push for what became known as the Page Extension.
Phase 1 of the Page Extension opened in 2003 and included construction of the Veterans Memorial Bridge over the Missouri River.
Phase 2 from Jungs Station to Mid Rivers Mall Drive finished construction in 2012.
The first half of the $118 million Phase 3 project opened to traffic from Interstate 64 to Route K in early October. The section from Route K to Mid Rivers Mall Drive will mark the final connection from I-270 in St. Louis County to Interstate 64 at Route N in St. Charles County. It will serve as an alternate for travel on Interstate 70 and Interstate 64.
Once the driving lanes are open to traffic there will still be some closures in place. The ramps at the Route 364-Route 94-Mid Rivers Mall Drive interchange will be open to traffic later this fall. This includes the ramp from eastbound Route 364 to westbound Route 94/Mid Rivers Mall Drive and from Mid Rivers Mall Drive to westbound Route 364. The new ramp from eastbound Route 94 to eastbound Route 364 will also open later this fall. Drivers can continue to use the detour up and over Mid Rivers Mall Drive to access eastbound Route 364.
Crews will also continue to work at the Route K and Route 364 interchange. Please use caution and slow down when traveling through those areas.
In addition, there will be off-peak lane drops on Route K for the next few weeks.
