Zim Road is one of those highways that you look at, and cannot figure why it exists. It historically connected the villages of Zim and Little Swan, neither of which still exist. The road was stitched together from 3 other east-west township roads, with a new diagonal section in the middle to tie it together. One can look at a topographical map and see the original path and location of the original bridge at this location prior to the new diagonal roadway being built. As it stands today, Zim Road, which is now partially state funded as a County State-Aid Highway, acts as a connector and river crossing between two much more heavily traveled north-south routes.

The bridge is relatively new, being nine years old when this was written. It is a very typical prestressed concrete girder bridge with a modern reinforced concrete deck and the new style slanted guardrails. The bridge has no decorative features. It will, however, last a great many years without requiring much in the line of routine inspections or maintenance. This is the true beauty of this type of bridge. It does the job very well, it is economical to build, and economical to maintain. An interesting feature of this bridge is that it is built on a slight angle. The river crosses under the bridge at a slight angle, plus the roadway dips to the south just a bit on the west end. Rather than squaring up the river, it was decided to build the bridge as a parallelogram rather than a rectangle.
