Bikeway Improvements on Foothill Blvd at San Dimas Wash

The City proposes to widen the Foothill Boulevard Bridge by constructing separate bridge structures at both the north and south ends of the existing San Dimas Wash box culvert to match the appropriate width. The new bridge structures would be 35 feet long and would consist of a single-span reinforced concrete slab supported by cast-in-drilled-hole (CIDH) pile foundation. Construction of the superstructure would require temporary beams to support the concrete slab. The Foothill Boulevard bridge would have an 84-foot curb-to-curb roadway width that matches both existing approach widths. There would be a bike lane in both directions of travel. A concrete barrier with picket railing would be placed on both sides of the bridge. The project also includes approximately 750 feet of sidewalk with curb and gutter reconstruction extending from both the east and west bridge approach ends, as well as ADA-compliant driveway reconstruction at the Equestrian Center and flood control channel access roads. An underground gas line on the bridge would be relocated during construction. A fire hydrant, 12-inch waterline, and service connection to the Equestrian Center would be relocated during the project. The project would also include widening of the driveway to Flood Control properties on the north and south sides, as well as possible driveway access to Starberry Farms.
