Frequently Asked Questions

Will MoDOT close the road during construction?

Yes, all of the routes will close at the bridge during construction.

What is the planned detour?

There are no planned, signed detours. Motorists will need to seek an alternate route during the closures.

Why not build a bypass?

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

Will MoDOT need to acquire any right of way?

No, MoDOT did not need to acquire any temporary or permanent right of way for this project.

How long will construction take?

The contractor will have 304 days to complete the construction of all four bridges per contract.
