In 1908, Marion W. Savage, owner of the race horse Dan
Patch, sought to build a railroad to connect his farm and other rural
areas south of Minneapolis with the railroad network at Minneapolis.
Work began on the Minneapolis, St. Paul, Rochester and Dubuque Electric
Traction Company in 1908, and the 37-mile line from Northfield to 54th
Street in Minneapolis was completed in 1910. Grading was started on an
extension south to Faribault in 1911, but this project was never
completed. In 1913, work began on a 14-mile line to Minneapolis,
extending from Auto Club Junction north to Luce Line Junction. In
addition, the Electric Short Line Terminal company constructed an
additional 4 miles from Luce Line Junction into downtown Minneapolis.
Located between Nicollet Avenue and Lyndale Avenue, this through plate girder bridge crosses Interstate 494. Built in 1958 as I-494 was being constructed, the bridge consists of two 62-foot through plate girder spans, set onto concrete substructures. While the bridge does not utilize as many decorative features as other early Interstate-era grade separations, the bridge does utilize a decorative pier. Spans like this were commonly constructed during the Interstate Highway era throughout the United States, as they were easy to construct and durable. Overall, this bridge appears to be in fair to poor condition, with significant rust seen throughout the bridge. The author has ranked this bridge as being locally significant, due to the early Interstate Era-design. Due to the proposed widening of I-494, this bridge will likely be replaced in the coming years.
