This supplemental document consists of as-built drawings for the Murray Bridge component of Washington County, Oregon's comprehensive SW Walker Road/SW Murray Boulevard Intersection Improvements project (Project #100238). The as-built drawings document the specifications and final construction details for the deconstructed existing Murray Bridge over Cedar Mill Creek, which was rehabilitated and reinstalled on Walker Road over Cedar Mill Creek as part of the broader $20 million to $40 million infrastructure enhancement initiative. The project encompasses multiple critical components including a new bridge on Murray Boulevard over Cedar Mill Creek, installation of box culverts under Walker Road and Far Vista Street for North Johnson Creek, traffic signal installation at two intersections, roadway widening of approximately 2,350 linear feet on Murray Boulevard and 2,450 linear feet on Walker Road with new curb and sidewalk, gravity retaining walls, stormwater collection and conveyance systems with water quality treatment facilities, approximately 875 feet of 42-inch TVWD waterline, and approximately 500 feet of CWS sanitary sewer. The mandatory pre-bid meeting was scheduled for January 28, 2026, at 2:00 p.m., with questions due by January 30, 2026, and electronic bids required by February 4, 2026, at 1:00 p.m. The project includes two distinct completion deadlines: February 14, 2027, for TVWD waterline installation and activation, and August 31, 2028, for all remaining work, with liquidated damages of $1,100 per calendar day for the first deadline and $2,700 per calendar day for the second deadline.
