[Supplemental]_Walker_Bridge_Widening_As-builts.pdf

This supplemental document contains as-built drawings for the Walker Bridge Widening component of the SW Walker Road/SW Murray Boulevard Intersection Improvements project in Washington County, Oregon. The as-built documentation records the final constructed conditions of the bridge widening work, including the deconstructed and reinstalled Murray Bridge over Cedar Mill Creek on Walker Road. These technical drawings serve as the official record of completed construction and are essential for project closeout, future maintenance, and verification that work was performed in accordance with contract specifications and approved designs. The as-built plans document all structural elements, dimensions, material installations, and any field modifications made during the construction process.
