Route K Traffic Impacts (updated 10/9)

Traffic impacts on Route K between Route N and South Outer 364 will continue for the next several weeks.  Weather permitting, crews will have one lane closed on northbound Route K, Monday through Friday from 8 a.m. to 3:30 p.m. and one lane closed southbound from 9:30 a.m. to 3:30 p.m.  In addition, one lane will be closed in both directions of Route K on Saturdays from 7 a.m. to 3:30 p.m.  To receive updates on the impacts, send an email to Route.364@modot.mo.gov.

Eastbound Route 94 Detour (updated 10/5)

Traffic on eastbound Route 94 is detoured at Mid Rivers Mall Drive.  Traffic must exit at Mid Rivers Mall Drive, go through the intersection and back onto eastbound Route 94/Route 364.  The detour will remain in place until the second half of the new Route 364 opens later this fall.  To see a map of the detour, click here.

Westbound Route 364/Route 94 Lanes (updated 10/5)

Drivers coming from westbound Route 364/Route 94 have two lanes across the new bridge to continue onto westbound Route 94.  This will be a temporary traffic condition until the new Route 364 opens.  At that time, the ramp will be two lanes - one coming from westbound Route 94/Route 364 and one coming from Mid Rivers Mall Drive.


About the project:

MoDOT, St. Charles County and local municipalities teamed together to allocate $118.2 million towards building Route 364/Page Phase 3.  The $118.2 million was used for purchasing property, utility relocations, design and construction.  The project includes building an improved connection from Page Phase 2 at Route 94 and Mid Rivers Mall Drive to I-64/US Route 40/61 at Route N.

MoDOT used a Design-Build contracting process to have contractor teams compete to win the contract.  The Missouri Highways and Transportation Commission approved the contract on February 6, 2013, awarding the project to the Page Constructors Joint Venture, which includes Fred Weber Inc. and Millstone-Bangert Inc (now known as Millstone Weber) along with Kolb Grading and lead designer, Parsons Transportation Group.

What will be built?

Page Constructors is designing and building a four lane divided freeway for nine miles from Route 94 at Mid Rivers Mall Drive in St Peters to Interstate 64 in Lake Saint Louis.  The new highway will include the following:

  • additional ramps connecting Route 94 and Mid Rivers Mall Drive to Route 364

  • bridge over Motherhead Road

  • Gutermuth Road bridge over Route 364

  • Single point interchange at Route K with widening of Route K to six lanes north and south of the interchange

  • roundabout at Bryan Road with north outer road extended from Stump Road to Bryan Road

  • bridge over Hanley Road

  • bridge over Henke Road with ramps to and from the east

  • new ramps to complete the cloverleaf interchange at I-64

Schedule for construction:

Route 364/Page Phase 3 construction started in May 2013.  There will be construction activity along all nine miles of the project until the new road opens in sections in the fall of 2014 with the entire new road open by the end of October 2014.  The entire project will be complete by late November 2014.
