here in daylight
This is a multipurpose bridge - Eads Bridge at LaClede's Landing
the top level is for vehicular traffic the lower for passenger tains:
Both the construction and design of Eads Bridge set precedents in bridge building. It was the world´s first alloy steel bridge; the first to use tubular cord members; and the first to depend entirely upon the use of the cantilever in the building of the superstructure . Pneumatic caissons were used for the first time in the United States in the construction of the piers, which were sunk to unprecedented depths (96 ft. below mean water level and 122.5 ft. below the City Directrix). Eads also invented the sand pump to remove gravel, sand and silt from the caissons so that the sinking operation could work without interruption. Finally, it was the first large bridge to span the Mississippi River, and it was the first to carry railroad tracks.
