Designed in 1877 by engineer Wendel Bollman (1814-1884), the Lombard Street Bridge is believed to be the only bridge of its kind in existence. It is a unique, bifurcated water-main form which is an integral part in the support system for the bridge. Other water-main bridges are constructed through the use of the arch rather than the truss. It was built to carry city traffic over the Jones Falls stream and water through the design system. The bridge was disassembled c. 1975 because it could no longer handle the heavy volume of traffic on Lombard Street, one of the principal east-west streets in Baltimore. It is stored on the property of the Baltimore Streetcar Museum. The bridge is also significant for its association with Wendel Bollman, a self-taught engineer who invented the Bollman truss in 1852. The Bollman Truss bridge became one of the most outstanding advances in 19th century bridge design. Bollman designed many bridges for the B & O Railroad and for various other firms from Chile to Iowa, including Maryland. He built 12 bridges in Baltimore, including the Lombard Street Bridge, which carried city street traffic over the Jones Falls and water through the original design system for almost a century.
Museum officials have attempted to erect the bridge as a pedestrian bridge spanning the nearby Jones Falls, but have been barred from such reuse by the Army Corps of Engineers.
