Project Costs: Estimated Construction Cost $27,000,000
The Hazel Avenue Widening Project consists of three phases. The first phase is from Curragh Downs Drive to US Highway 50 and includes the widening of the existing bridge on the downstream side of the existing bridge over the American River.
Ultimately, the completed structure will provide a safe and comfortable river crossing for vehicles, bicyclists, pedestrians, and equestrians, including improved access to the American River Parkway.
The Phase 1 project will include the construction of a new bridge structure (pre-stressed, pre-cast, concrete I-girder), supported on three independent new piers (matching the bents on the existing piers), and foundations, with deck at the same level as, and connected to the existing deck. The geometry includes a 12-foot multi-purpose path on the west side of the bridge, 5-foot wide on-street bike lanes on both sides of the bridge, and a 9.5-foot wide sidewalk on the east side. In addition, the project includes work in the American River, including sheet piling for the pier foundations and temporary trestles on driven piles for access and work area for work in the river. Other work includes roadway widening, construction of Class I bike paths, retaining and sound walls, street lighting and the installation of a pre-fabricated pedestrian bridge.
The Hanna Group’s scope of work includes pre-construction services, resident engineering, roadway/structures inspection, construction staking and materials testing.
