Located on the north edge of the University of Minnesota campus, little is known about this girder bridge that carries the BNSF and Union Pacific yard tracks over 15th Avenue Southeast. Originally built in 1891, the southern portion of the bridge was rebuilt in 1921. The bridge features two distinct sections, a through plate girder section (the Omaha Road section), and the deck plate girder section (the Great Northern section). The Omaha Road section consists of a single through plate girder span built in 1918, approached by concrete slab spans. The Great Northern section consists of a single deck plate girder span, approached by a concrete slab span on each end. The Great Northern section was built in 1921. The bridge sits on steel piers and concrete abutments. Overall, the bridge appears to be in poor condition, with deterioration seen throughout the structure. The author has rated the bridge as locally significant, due to the common design. Research of this bridge is ongoing.
