Vertical endpost Whipple truss (two span.) using Keystone Columns built to the Jacob Linville's patent 50,723. Linville was President of Andrew Carnegie's Keystone Bridge Co. It is likely that the bridge superstructure was entirely manufactured by Keystone (not just the namesake columns) and erected by Penn Bridge Co.
In 1907 the bridge began carrying trolley traffic but was deemed insufficiently strong to carry the load. Due to a political disagreement as to what type of bridge should be used in its replacement, a 'temporary' reinforcement in the form of a Baltimore through truss was built around the existing Whipple in 1912. The 'temporary' reinforcement stood for over 102 years.
