To enhance earthquake safety, crews retrofitted the bridge seat. This is the ramp that sits between the shoreline and the transfer span, which is a moveable bridge.

How You Benefit
Cross GlyphImproves Safety
This project strengthened the bridge seat by installing additional plates under the bridge seat to hold the transfer span in place. This reduces the likelihood of the transfer span being shaken off the bridge seat during an earthquake.
