Three Lake Bridges-Replace Bridge and Upgrade Bridge Rail (Morrison, Robinson, and Kelsey Creek)

Three Lake Bridges-Replace Bridge and Upgrade Bridge Rail (Morrison, Robinson, and Kelsey Creek)

Caltrans proposes to upgrade the bridge rails and shoulder widths at Morrison Creek and Robinson Creek, and to replace the bridge at Kelsey Creek in order to support the widening and new rails, in Lake County on SR 20 PM 16.81 in Lucerne, SR 29 PM 50.82 in Upper Lake, and SR 175 PM 19.48 in Cobb. If existing structure(s) could not have supported the new railings and bridge widening, then the structure(s) would be replaced.The proposed project would bring all three bridges to current design standards and would construct standard transitions to and from improved structures. The upgraded bridge rails on all three structures would consist of concrete barriers modified with architectural treatment and equipped with tubular bicycle railings to accommodate the bicyclists and pedestrians that share the corridor with other modes of traffic. A standard Midwest Guardrail System (MGS) would be installed at both the approaches and departures of all three bridges, and vegetation control pads for the new MGS would be constructed to limit future vegetation control maintenance activities.
