Once the bridge heading southwest out of Union Station (Union Depot) in Oklahoma City for the Saint Louis-San Fransisco (Frisco) railroad. Crosses the Oklahoma River (then the North Canadian River) out of Lake Overholser. Now it is used as a pedestrian bridge to get across the Oklahoma River from Wheeler park at Western Ave to S McKinley Ave at SW 11th.
To get to the bridge, there is a gravel "road" just north of the river on Western going west. Follow this to the bridge. There is nowhere to park at the west side of the bridge off McKinley. If you are using the Oklahoma River Trails along here, you go right under this bridge. It is just west of the Wheeler ferris wheel. When I was there to take pictures, the University of Oklahoma women's 8 rowing team were practicing.
