Proposed Project Timeline (Subject to change)

Design, Public Input and Right of Way Acquisiton Phase

Contractors Bid on Projects

The projects are currently scheduled in the December 2019 letting. At that time contractors will be able to submit competitive bids for the projects.

Contract Awarded

The Missouri Highways and Transportation Commission  reviewed all bids and awarded the contract to Boone Construction Company at their January 2020 meeting.

Notice to Proceed

The Notice to Proceed date is the earliest the contractor may begin work on the project. This is currently scheduled for February 2020.

Construction Underway

Boone Construction Co. , working with the Missouri Department of Transportation,  reopened the Florida Creek and Stream Bridges, located west of Route AB on the afternoon of Wednesday, Oct. 28. The bridges closed in late July as part of a project to replace four bridges west of Maryville on Route 46.

The replacements of the White Cloud and Big Slough Creek bridges, located east of Route AB, were completed on Thursday, Nov. 12, 2020.     


Completion Date

Four bridges (Big Slu, Florida Creek, Stream and White Cloud Creek) were replaced in the fall of 2020. The roadway reopened in full on Nov. 12, 2020.

Proposed Detour Routes

Most traffic will be directed around the closures via a signed detour on Route 113 and U.S. Route 71. Local traffic may utilize Route AB between the bridge projects.

Frequently Asked Questions

Q: Why is MoDOT closing the road during construction?

A: Closing the bridges saves taxpayer money by allowing the contractor to work more efficiently and will result in a shorter construction period.


Q: What is the current detour?

A: During the bridge replacements, motorists should utilize the signed detour on U.S. Route 71, U.S. Route 136, and Route 113 or AB to travel around the closures. Drivers are urged to stay alert and pay attention to all roadway signing and barricades.


Q: Why not build a bypass?

A: Based on the cost/benefit ratio, building a bypass would not be a good use of taxpayer funds.


Q: Will MoDOT have to purchase any right of way?

A: Some right of way acquisition may be necessary for these projects. The Right of Way staff with the Missouri Department of Transportation will reach out to any property owners who may be affected. See an example of some proposed right of way above left.
