St. Louis County Highway CSAH-7 is a larger connector highway that starts just a few miles north of the Duluth International Airport, and runs north parallel to (and west of) US-53, ending in Virginia, Minnesota. The highway serves all types of traffic from local farmers, landowners, commuters, and the mining industry.

The CSAH-7 bridge is located a few miles south of the village of Forbes. The St. Louis River, which had been flowing south, has made a turn and is now flowing from the east. There are several bridges in this area in close proximity, including the DM&IR bridge, Forbes Dam, DW&P bridge, a regional trail, two spans of US-53, and a township road.

This bridge is very typical of the prestressed concrete girder bridges that are favored by MN-DOT for long life and ease of maintenance. In this case, the bridge has two span sections supported by a single reinforced concrete T-pier. The bridge has full width lanes, wide shoulders, and the modern style guardrails. Despite being 12 years old in these photos, the bridge appears to be more or less in like new condition.
