Route 364 - In Planning

Phase 3 logoRoute 364 upgrade - Phase 3

MoDOT, St. Charles County and the local muncipalities have teamed together to allocate $100 million towards building Route 364 Page Phase 3.  The $100 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 will use a Design-Build contracting process.  Contractor teams will compete to win the contract and they will design and construct the project.  The procurement process will begin in summer 2012 with selection of a Design-Build team in early 2013.  

Property acquisition began in late fall 2011.

What is the Design-Build contracting process?

With Design-Build, the design and construction are completed by the same contractor on an accelerated time frame. This allows the road improvements to be constructed faster than the usual design-bid-build process.  It will also allow contractors to incorporate innovative cost-saving ideas that will allow taxpayers to get more for their money, without sacrificing the quality needed for the road.  The Page Phase 3 Design-Build contractor will be selected in early 2013.  At that time, the contractor will provide the construction schedule to complete the improvements no later than December 2014.
