Document Description
The east roadway approach is cut into the hillside with a steep ravine to the right. At the bridge the road crosses to the right side of the hill and continues up the ravine, paralleling the creek to its south. The creek flows eastwardly, and falls steeply immediately after the bridge. The road will be widened to 18 ft plus 2-ft graded shoulders to meet the min width required by the American Association of State Highways and Transportation Officials design specifications. To accommodate the wider roadway, the road centerline would be shifted south. This will require additional cut into the hillside for the east approach, and a side-hill viaduct along the creek for the west approach. The new bridge profile will closely match the existing. The new approaches will conform to the existing roadway as quickly as possible while providing adequate alignment curvatures in conformance with design speed standards. The existing Redwood Rd Bridge would be removed and replaced with a 27'-6" long by 22'-8" wide single span cast-in-place concrete slab bridge with cast in place concrete bridge abutments. The abutments are expected to be founded on spread footings due to the shallow depth to bedrock. However, cast in drilled hole concrete piles will also be considered for foundations. The southwest bridge corner will cantilever approx five ft beyond the end of the abutment wall so that creek flows are not cut off. Caltrans type 116 or 216 metal tube bridge railings will be used on the bridge.
