Merced Seismic Retrofit
The California Department of Transportation (Caltrans) proposes to seismically retrofit seven bridges in Merced County to increase their structural integrity in case of a seismic event and upgrade deficient bridge railings to current standards.
The purpose of the project is to upgrade the following bridges to current seismic standards:
Bear Creek Bridges, both northbound (Bridge Number, 39-0009 L) and southbound (Bridge Number 39-0009 R) on State Route 59 in the City of Merced.
San Joaquin River (Santa Rita) Bridge eastbound (Bridge Number, 39-0028 L) on State Route 152 in Merced County.
Eastside Bypass Channel Bridges, both eastbound (Bridge Number 39-0034R) and westbound (Bridge Number 39-0034R) on State Route 152 in Merced County.
Los Banos Creek/West Branch Mud Slough (Bridge Number 39-0090) on State Route 140 in Merced County.
San Joaquin River Bridge (Bridge Number. 39-0092) on State Route 140 in Merced County.
The bridges were identified as seismically vulnerable by the Office of Earthquake Engineering, and the Office of Structure Maintenance and Investigations identified a need to upgrade the non-standard bridge railings at each project location. The bridges are vulnerable to collapse during an earthquake if not retrofitted to withstand a maximum credible earthquake event.
Five of the structures were found to have obsolete bridge railing. Under the provisions of Moving Ahead for Progress in the 21st Century (MAP-21), each state uses the nationally defined performance measures for bridges, which identify a bridge’s condition as good, fair or poor. The project bridges have non-standard railings in “poor” condition.
Estimated Total Project Cost: $133,500,00
