This is a CAD files archive related to the SW Walker Road/SW Murray Boulevard Intersection Improvements project (Project 100238) in Washington County, Oregon. The deliverable package contains contractor CAD files supporting a major infrastructure improvement project estimated between $20,000,000 and $40,000,000. The scope of work encompasses construction of a new bridge on Murray Boulevard over Cedar Mill Creek, deconstruction and reinstallation of the existing Murray Bridge to Walker Road, installation of two box culverts under Walker Road and Far Vista Street for North Johnson Creek, and traffic signal installation at two intersections. Additional work includes approximately 2,350 linear feet of widening on Murray Boulevard and 2,450 linear feet on Walker Road, both with new curb and sidewalk construction, gravity retaining walls, stormwater collection and conveyance systems with water quality treatment, approximately 875 linear feet of 42-inch TVWD waterline, and approximately 500 linear feet of CWS sanitary sewer. The project also encompasses grading, drainage, paving, signing, striping, illumination, signal modifications, landscaping, and utility work as specified in the contract documents.

The CAD files archive serves as technical documentation supporting the design and construction phases of this comprehensive intersection and infrastructure improvement project. These files provide contractors with the necessary technical drawings and specifications required for bidding and executing the work according to project plans. The project represents significant infrastructure investment in Washington County's transportation and utility systems, with deliverables addressing both surface transportation improvements and subsurface utility installations coordinated across multiple agencies and service providers including TVWD and CWS.
