Route 364 (Page Extension)

Phase 3 logoRoute 364 Page Ave Phase 3


MoDOT, and its contractor Page Constructors, will be permanently closing a connection between Henke Road/Technology Drive and I-64 on Monday, April 28.  This means there will be no access from Henke Road onto Route N and onto Interstate 64.  This is part of the final design for the Page Avenue Route 364 Phase 3 project which will tie into Henke Road.  Motorists should use Old Highway N or Ronald Reagan Drive as alternate I-64 crossings to access Route N to the west or the I-64 ramps.  This closure will go into effect after morning rush hour on April 28.

Changes have been made to the design of one 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. As design moved forward, we determined we needed to make a change to provide access to a property owner.  The westbound Route 364 exit to Bryan Road was changed from a folded diamond interchange to a roundabout.  In addition to providing access to the property owner, this will be a better design for traffic overall.  This change means the new Route 364 will now open in two phases instead of three. The stretch from I-64 to Route K will open October 3, with all lanes of the new road still scheduled to open by October 31.

MoDOT, St. Charles County and the local municipalities have 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 details:

  • 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 of Route 364 Phase 3:

Route 364 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.
