Bridge Documentation

View Historic American Engineering Record (HAER) Documentation For This Bridge

This bridge was once part of a larger viaduct system which has been removed. The main span remains today, continuing to give the structure historic significance. A distinctive structure, the bridge is skewed, which is uncommon for pin-connected through truss bridges. More rare however is the use of vertical end posts for a simple Pratt truss like this. The truss itself appears to retain excellent historic integrity. The bridge's severed western end was reconnected to a zigzagging ramp system and the historic bridge was re-decked to open it for non-motorized use. Today, the bridge is a popular crossing and walkway, with the bridge offering excellent views of the Pittsburgh skyline.

The total length of this bridge is an estimate of the length of the original remaining bridge from western pier to eastern abutment. The main span length is per Historic American Engineering Record.
