Coast Highway Bridge Replacement Project

Coast Highway Bridge Replacement Project

The proposed project would replace the existing bridge on Coast Highway over the San Luis Rey River. The new bridge would replace the existing bridge immediately west of the existing alignment to maintain service on the existing roadway and bridge during construction. The proposed project would be a cast-in-place post-tensioned concrete box grinder bridge on column piers along a new alignment immediately west of the existing bridge. No additional traffic lanes are proposed for the project; the existing two-lane bridge would be replaced with another two-lane bridge. A roundabout would be constructed at the Monterey Drive/Coast Hwy intersections. Construction of a temporary trestle adjacent to the existing bridge would facilitate access across the river. Cofferdams and bubble curtains may be required to construct some of the new bridge concrete piers and supports. Cofferdams would be installed along the banks of the San Luis Rey River in order to construct the piers and supports on land while bubble curtains would be used to construct the piers and supports within the river. The trestle and cofferdams will be removed upon construction completion.
