In 1862, the First Division of The St. Paul and Pacific Railroad Company constructed the first railroad in Minnesota, a 10 mile route between St. Paul, Minnesota and Minneapolis (St. Anthony), Minnesota. The railroad quickly spurred growth throughout the Twin Cities, and was extended north and west during the following years. In 1879, the railroad was purchased by the James J. Hill controlled St. Paul, Minneapolis & Manitoba Railway (StPM&M). This route became one of the heaviest used routes on the StPM&M system. By 1907, the StPM&M would be purchased by another James J. Hill railroad, the Great Northern Railway (GN). Great Northern connected to Seattle and Portland on the West Coast, and to the Chicago, Burlington & Quincy Railroad (CB&Q) in St. Paul. In 1970, GN merged with rival Northern Pacific Railway and the CB&Q to form Burlington Northern Railroad. BN was in turn merged with Atchison, Topeka & Santa Fe Railway in 1996, to form BNSF Railway. BNSF currently operates this line as the Midway Subdivision, the southern of two parallel BNSF main lines through the Twin Cities.

Located in Northeast Minneapolis, this standard concrete slab bridge carries the BNSF Midway Subdivision across Monroe Street Northeast. Built in 1924 as part of a grade separation project, the bridge features two 50-foot concrete encased beam spans, approached by a 21-foot concrete slab span on each end. The entire bridge is set onto concrete substructures. The main spans of the bridge are 24-feet long, while the approach spans are 10-foot spans. The piers of the bridge utilize a decorative design typical for this era, and the railings of the bridge are also decorative. The bridge is located next to the former Northern Pacific Bridge and the former Northern Pacific "E" line bridge. Bridges such as this were commonly used as grade separations in cities throughout the United States, due to the durability and ease of construction. Overall, this bridge appears to be in fair to poor condition, with some spalling and concrete defects noted. The author has ranked this bridge as being locally significant, due to the common design.
