Hennepin Canal Lock 17 Roller Bridge

It was built to provide access to the farm fields on the opposite side of the canal. The nearby truss bridge is not capable of handling the large modern farm equipment.

It also provides an example of a bridge type that they did construct at some locations back in the days when the canal was in operation.

I believe this bridge is a reproduction of a type of original roller bridge at Lock 2. There is an original steel truss bridge at Lock 17, so there would be no reason to have two bridges at that location. The appearance of the Lock 17 roller bridge indicates it is modern.
