ATT B Plans~27.pdf

This is a technical engineering drawing package from the Oregon Department of Transportation for the OR138W at MP 16.47A & 15.65A Marvin Hill Culvert Repair Project located on the Elkton-Sutherlin Highway in Douglas County, scheduled for August 2025. The project involves drainage infrastructure repair work at two specific milepost locations, including culvert repair, roadway construction, traffic control measures, erosion and sediment control planning, geotechnical considerations, and hydraulic management with temporary water management plans.

The drawings include detailed construction specifications for culvert repair sections, typical cross-sections showing pavement layers, aggregate base materials, geotextile installation, stone embankment material placement, and slope stabilization measures. The project requires compliance with Oregon Standard Specifications for Construction and includes provisions for traffic control during construction with temporary concrete barriers, lane closures, and maintaining vehicle access. The plans show coordination between multiple engineering disciplines including roadway design, drainage systems, traffic management, erosion control, geotechnical engineering, and hydraulic design, with all work to be performed according to ODOT design standards and approved by registered professional engineers.
