Route 364 (Page Extension)

Phase 3 logoRoute 364/Page Ave Phase 3


Counting Down to Completion

You're invited...to walk, run and bike the new Route 364/Page Phase 3 from I-64 to Route K on October 4 (click here for more information)



***More Changes Coming to Mid Rivers Mall Drive/Route 94***

More changes are coming to the Mid Rivers Mall Drive/Route 94 area as crews work to make the final connection from Route 94/Route 364 to the new Route 364/Page Phase 3.  The first step will be to shift traffic to the new ramp from Mid Rivers Mall Drive to westbound Route 94.  Drivers on westbound Route 94/Route 364 will then be moved over to the new bridge following a weekend closure of westbound Route 94/Route 364.  The date of the upcoming weekend closure will be available in the coming weeks.

Making the final connection from Route 94/Route 364 to the new Route 364/Page Phase 3 will require traffic on eastbound Route 94 to be detoured at Mid Rivers Mall Drive for about a month. Drivers will have to exit eastbound Route 94 at Mid Rivers, go through the intersection and back onto Route 94/Route 364. The exact date of the detour and further details will be available in the next few weeks.

***Lane Shifts on Route 364 (updated 8/6/14)***

Motorists traveling on westbound Route 364 can expect traffic shifts at Mid Rivers Mall Drive for the next several weeks as part of the Route 364/Page Phase 3 project.  Crews on Thursday, August 7 will start work to narrow the lanes and shift them to the left.  This will allow for the completion of the tie in work for the new ramp from westbound Route 364 to westbound Route 94.  In addition, the speed limit will be lowered to 45 mph.

***Traffic Changes for Mid Rivers Mall Drive/Route 94***

Temporary traffic changes have been made at the intersection of Mid Rivers Mall Drive and Route 94.  The ramp from Mid Rivers Mall Drive to westbound Route 94 is narrowed and the merge has been shortened.  In addition, motorists will no longer be able to go straight onto westbound Route 94 from the left-most lane of the North Outer Road.  That lane is now a left turn only lane onto Mid Rivers Mall Drive.  The middle lane will still go to westbound Route 94.  The changes are necessary so crews can work on the connection from Route 94 to the new Route 364. 

***Henke Road/Technology Drive Connection to I-64 Closed***

MoDOT, and its contractor Page Constructors, has permanently closed a connection between Henke Road/Technology Drive and Interstate 64.  That means there is no access from Henke Road onto Route N or Interstate 64.  This is part of the final design for the Route 364/Page Phase 3 project which will tie into Henke Road.

Changes have been made to the design of an intersection on the Route 364/Page Phase 3 project.  Route 364 is a design-build project, which means the design of the road is happening at the same time as construction.  The westbound Route 364 exit to Bryan Road will now be a roundabout instead of a folded diamond interchange.  The change means Route 364 will now open in two phases instead of three. The stretch from I-64 to Route K will open in early October, with all lanes of the new road open by October 31.

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 will be 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., Millstone-Bangert Inc., 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.
