|June 2007 ( 36.9862 Degrees, -122.0237 Degrees) Grant Street UC|
The Grant Street UC (36 0075) is a four span precast I girder bridge on two-column bents. During the earthquake the expansion joints banged together spalling some concrete (see photo above), the bearing keeper plates were knocked off at the abutments (see photo below), and the embankments around the abutments settled, which damaged the bridge approaches.
A repair contract was written after the earthquake (see figure below) and the bridge was also seismically strengthened with an infill wall retrofit in 1996. However, some of the earthquake damage can still be seen today (see figure at bottom).
