Document Description
To replace the Echo Summit Sidehill Viaduct (Bridge #25-0044) at PM 67.3 on US 50 in El Dorado County. The viaduct was identified in the Structures Maintenance & Investigation (SM&I) list of outstanding work due to its poor condition and ongoing problems including high corrosive chloride contents in the concrete deck surface and bridge superstructure and substructure, concrete spalling, and severe transverse and longitudinal cracks in the concrete deck. Bridge replacement was recommended in the Caltrans SM&I structure replacement and improvement needs (STRAIN) report.
