Paddock Viaduct. Low-water crossing and ferries originally provided the only access across the Trinity River at this location, connecting the downtown area of Fort Worth with northern sections of the city. A two-lane suspension bridge, constructed near this site in the 1890s, proved inadequate for the growing population. This span, designed by the St. Louis firm of Brenneke and Fay, was built in 1914. It was the first reinforced concrete arch in the nation to use self-supporting, reinforcing steel. The bridge is named in honor of B.B. Paddock, former State Legislator and Mayor of the City. #3905
