Weber Creek Bridge Replacement – County of El Dorado, CA
The Weber Creek Bridge Replacement Project included the construction of a new single span, 42-foot x 10-inch width, 165-foot, two-lane, cast-in-place prestressed concrete box girder bridge with abutments founded on spread concrete footings and pressure grouted dowel anchors.
The bridge was constructed on a new alignment west of the existing bridge, which provided for improved horizontal alignment with a larger radius curve, improved vertical alignment, wider lanes and shoulders facilitated by the construction of retaining walls. In order to accommodate the alignment shift, three major retaining walls were constructed.
Other construction components include:
- Temporary shoring systems to facilitate roadway construction, structures and drainage systems
- Reinforced concrete structure approach slabs
- Textured/architectural and anti-graffiti treatments of concrete surfaces
- Placement of rock slope protection at the bridge abutments and stream bank
- Structural section for the new roadway
- Metal beam guard railing
- Installation of roadside signs
