The bridge is a very typical prestressed concrete girder bridge. It has modern features such as the reinforced concrete deck and slanted guardrails. The bridge is supported by two very hefty T-piers sitting on deep foundations. While the river looks rather tranquil in these photos, it can become a raging torrent during spring run-off and other high-water periods. In fact, water can rise to within a foot of the bridge girders. As a result, the bridge piers need to be able to withstand both the pressure of high water and impacts from the debris that is carried downstream by the water.
One interesting feature of the bridge is that it is built on a slight curve. When the bridge was built, it was built to the south side of the existing bridge. The existing bridge was built straight in line with Arkola Road. To connect the new bridge to the existing roadway, the roadway needed to be realigned slightly. A slight curve was added to the bridge to reduce the length of the roadbed that needed to be realigned.
The photo above is a view of the upriver north side of the Arkola Road Bridge as seen from the parking area located on the east bank of the Saint Louis River. A trail leads down to the water to a canoe landing. The photo below is the bridge plate.
