Document Description
The project is limited to the replacement of the existing, but functionally obsolete Westside Road bridge over Canyon Hollow Creek, with a wider two-lane, three-span, cast-in-place reinforced concrete slab bridge. The new bridge will be approximately 4-feet wider than the existing bridge, with a total deck width of 40 feet and 11 inches and a length of 84 feet. The soffit elevation will match the existing bridge and will be set to pass the 100-year flood event with no freeboard. The new bridge will be supported on concrete piles and columns at the piers, with reinforced concrete diaphragm abutments supported on concrete spread footings.
The foundation system of the new bridge will consist of 30-inch cast-in-drilled-hole piles. However, driven piles may be needed to support falsework. The bridge abutments will sit partially below the ordinary high-water mark (OHWM), with two armored piers in the channel. Approximately 180 cubic yards of rock slope protection will be placed around the abutments, of which approximately 97 cubic yards would be placed below the OHWM. The in-channel work area extends approximately 25-feet upstream and downstream of the new bridge to allow access into the channel during construction and underground utility relocations.
Additional work will include extending the sidewalk along approaches, storm drain modification, paving, striping, and sign installation. Construction will be staged to allow a single lane of alternating traffic, controlled by temporary signals.
