The Western Federal Lands Highway Division issued a Notice to Prospective Bidders for the WA FLAP JEFFER 134309(2), Two Trout Creek Culvert Replacement project. This project, near Milepost 0.5 on Oil City Road, aims to improve aquatic organism passage (AOP) by replacing an undersized corrugated metal culvert with a new AOP structure. The scope includes culvert removal and installation, roadway reconstruction, new guardrail installation, and placement of in-stream logs for fish habitat. Prospective bidders are encouraged to view the project site as winter conditions may impede access, and no Federal Highway Administration personnel will provide tours. Technical questions should be submitted via email to wfl.plans-spec@dot.gov, and general questions to wfl.contracts@dot.gov. Solicitation documents will be available in Winter 2025 on SAM.gov, where interested parties can follow the solicitation for automatic notifications.

The WA FLAP JEFFER 134309(2) project involves replacing a failing culvert at Oil City Road MP 0.5 in Jefferson County, Washington State, to improve aquatic organism passage in a Hoh River tributary. Located 16 miles south of Forks, this 0.1-mile project has an estimated cost between $2,000,000 and $5,000,000. The solicitation is tentatively scheduled for Fall/Winter 2025, with completion by Winter 2026. The work includes extensive earthwork, erosion control, construction of a reinforced concrete box culvert (18' span, 12' rise), guardrail systems, turf establishment, and environmental design elements such as root wads and streambed material. Key tasks involve construction surveying, quality control, contractor sampling, and adherence to construction schedules, all performed using FP-24 specifications and US customary units.

The WA FLAP JEFFER 134309(2) project involves replacing a culvert at Two Trout Creek in Jefferson County, Washington. This preliminary plan outlines the construction of a box culvert, traffic control measures, and environmental protection. Key elements include installing a precast reinforced concrete box culvert, managing temporary stream diversions with sandbags and waterproof membranes, and implementing erosion control using silt fences, fiber rolls, and check dams. The project also details guardrail installation, streambed material mitigation for fish passage, and structural specifications for the culvert and associated components. The plan emphasizes adherence to federal highway administration standards and addresses grading, roadway design, and survey control.
