Project Status: Project is complete, open for traffic.


Why is MoDOT doing this project?

Built in 1959, the Route HH Bridge carries about 1,020 vehicles a day. It is in poor condition and has faced several emergency closures to address needed repairs.

How will this project benefit me?

If the bridge was left as is, the need for costly, unplanned and unscheduled repairs would increase, along with the real possibility that the bridge could be closed indefinitely until complete bridge replacement could be scheduled sometime in the future. This is a long-term fix for the best life cycle cost, offering the best use of tax-payers' dollars 

What is the project schedule? 

Existing Route HH bridge was demolished in March, 2010.

The contractor has 95 calendar days, or about 3 months, to complete the project.

While the bridge is being rebuilt, there will be minimal lane closures on I-29 to complete work. However, all lanes on I-29 must remain open from 6 a.m. to 9 a.m. and 3 p.m. to 6 p.m. 

During the three months the bridge is closed, motorists will have to use detours to reach each side of the bridge. Northbound traffic will be detoured to Route 273/371 (Exit 20 ).  Southbound traffic will be detoured to Route 92 (Exit 18).

 How is this project funded? 

Through funding by the American Recovery and Reinvestment Act, MoDOT is able to accelerate the $1.1 million replacement to 2010.
