Early Planning and Construction
The need for a bridge connecting the city’s industrial heart with the growing communities on the opposite bank of the Patapsco River became increasingly apparent in the early 1900s. In 1913, the Baltimore City Council authorized the construction of a bridge, and the project was entrusted to the renowned engineering firm, the Baltimore Bridge Company.
The bridge was designed by renowned engineer Joseph M. K. Egan, whose firm had previously built several notable bridges in the area.
Construction commenced in 1914 and involved a complex process of laying foundations, erecting steel structures, and connecting the bridge’s various sections. The bridge was built using steel and concrete, materials chosen for their strength and durability. The construction process was fraught with challenges, including the need to navigate the busy river traffic and the difficult terrain.
