Scope Of Work
T.Y. Lin International (TYLI) was selected by the City of La Quinta, California, to provide Construction Management and Inspection Services for the Adams Street Roadway and Bridge Improvement Project over the Coachella Valley Storm Water Channel, known as the Whitewater River.
The new Adams Street Bridge is a four-span, cast-in-place box girderĀ onĀ 10-foot-diameter cast-in-drilled-hole (CIDH) pile shafts at the piers and 2-foot-diameter CIDH piles at the abutments. Using staged construction, the west side of the bridge was built first, using a temporary bypass road to maintain traffic flow. Upon completion, traffic was switched to the west side of the bridge and the east half was constructed. A closure pour connected both sides, with a raised median built over the closure pour.
Reconstruction of the Adams Street Roadway included construction of the embankment, subgrade, and the full roadway structural section. Wet and dry utility relocations involved water and sewer facilities, as well as conversion from overhead to underground. New installations included multiple drainage systems, sidewalks, curb and gutter, and ornamental bridge railings.
