Project Progress

Complete
Design phase

The Missouri Department of Transportation worked with consultant company Benesch to design a new bridge at the Grand River Overflow on Chariton County Route 139 near Sumner.

Contractors bid on the project

The project was part of MoDOT's Aug. 21, 2020 bid letting where contractors were able to submit competitive bids on construction projects.

Complete
Contract awarded

The Missouri Highways and Transportation Commission awarded a $1,434,099.25 contract to Boone Construction Co. at their Sept. 2, 2020 meeting.

Complete
Construction begins and road closure

The contract states the contractor may begin work as early as Oct. 15, 2020. The contractor closed the road to all traffic on Dec. 7, 2020.

The bridge construction began and a significant amount of dirt was placed at the site. Construction was paused to allow this dirt to settle and compact before construction on the new bridge can continue. Construction is set to resume May 17, 2021.

The planned, signed detour routes are noted below.

Complete
Road reopening

The road reopened to all traffic on Friday, Aug. 6, 2021

Frequently Asked Questions

 

Q. Why is MoDOT closing the road during construction?

A. Closing the road during the bridge replacement saves taxpayer money by allowing the contractor to work more efficiently. This will result in a shorter construction period.

 

Q. How long will the road be closed?

The road is scheduled to reopen in early to mid-August 2021. By contract, the contractor has 210 calendar days in which to complete the work.

 

Q. What is the planned detour?

There are two signed detours:

  • North: Route 139 to Route H to U.S. Route 65 to U.S. Route 36 to Route 5 to Route 139
  • South: Route 139 to U.S. Route 24 to Route 11 to Route CC to Route E to Route 139
  • See both routes above

 

Q. Why not build a bypass?

Based on the cost/benefit ration, building a bypass would not be a prudent use of taxpayer funds. A bypass could also have negative impacts and disruption to private property.

 

Q. Who can I contact if I have further questions?

A. Questions about the project may be directed to MoDOT Customer Service at 888 ASK MODOT (1-888-275-6636).
