Many local agencies in Minnesota lack funding to construct and maintain all the bridges in their roadway network. One way to lower costs is to reduce the number of bridges.
In Minnesota, some township bridges are on roads with low usage that have alternative accesses for nearby residents, but local officials are reluctant to remove the bridges.
To identify possible changes to how redundant and low-use bridges are identified and removed in Minnesota, the Local Road Research Board conducted a transportation research synthesis, “Local Bridge Removal Policies and Programs,” that explores how other states make bridge removal decisions.
Fifteen state DOTs responded to a survey about their processes, with varying levels of state oversight identified for bridge removal decisions. Researchers also examined funding and incentives offered by some DOTs to local agencies for bridge removal, as well as criteria for considering bridge removal.
A literature search of bridge design manuals, inspection manuals and bridge programs was also conducted to identify related policies and programs.

One thought on “A Look at Local Bridge Removal Practices and Policies”
As a retired civil engineer I question the wisdom of tearing down historic bridges. The act of demolition might be more expensive then repairing some bridges plus we will secure our heritage. Many old structures have been upgraded and unexpectedly turned into tourist hot spots,( Eifel Tower , rails to bicycle trails , Lower Town St Paul).Jeff
