Document Description
The proposed project includes replacing then existing bridge witha new bridge. in order to accommodate new bridge construction, the roadway alignment would shift to the north, and be built on half at time using staged construction to minimize the shift. The bridge will have 12-foot stnadard lanes, 8-foot shoulders, 6-foot sidewalks, and see-through bridge rails. The new structure would have continuous sidewalks on both sides of the bridge with longer segments west of the new bridge, and a shorter sidewalk segment tot he east of the new bridge. Due tot he centerline shift of the new bridge, the roadway widening will extend from the bridge and on to the existing roadway both west and east on SR 49. To the west, the project will connect near the Marshall Road intersection and to the east the project will connect near the Marshall Gold Discovery STate Historic Park. To the west of the bridge, the variable width two-way left turn lane and median islands with imrpoved contrast features to provide traffic calming and a 12 feet wide two-way left turn lane. Designated turn lanes would be palced where needed. Roadway profile and super correction work will be incorporated into the project. The Lotus Road intersection, as well as driveways, including Little Road, would be reconstructed to meet current design standards. Roadway profile and super correction work, would be incorporated into the project. R/W acquisition would be required because the new bridge's alignment shifts and the continued segments of the roadway require sight distance and standard roadway design. old piers 5 and 6 located in active channel will be removed per Caltrans Standard Specifications and Special Provisions. new structure will span active channel. SR 49 will be realigned to meet the new structure configuration. New bridge construction and old pier demolition will require temporary dewatering and or clear water diversion. Temporary trestle for construction stages will require placement fo approx. 25 drilled or driven piles. Trestle will remain in place for duration of project. Volume of material necessary for temporary dewatering/ water diversion activities include 400 cy clean river rock, 200 cubic yards concrete k-rail, 210 cubic yards structural materials for cofferdams, trestles and scaffolding. Existing maintenance access and staging area below bridge will be used during construction. Rock slope protection will be only placed at the new bridge abutments.
