Gray Creek Deck Replacement Project – Geotechnical Activities

The California Department of Transportation, District 2 in Redding, is preparing to conduct geotechnical investigations along State Route 299 in Trinity County between postmiles 6.26 and 6.50 in support of the Gray Creek Deck Replacement Project. The work will involve hollow stem auger and mud rotary borings to collect soil and rock samples, along with borehole geophysics and seismic refraction lines to evaluate subsurface conditions and identify potential geotechnical challenges. These activities are critical for informing the design and engineering of the deck replacement, ensuring structural integrity and long-term safety of the roadway infrastructure. The procurement is listed as a forecast opportunity with a posted date of June 12, 2026, indicating it is not yet an active solicitation but serves as a planning notice for interested contractors and consultants. The point of contact for inquiries is Julie McFall, Office Branch Chief, who can be reached via phone or email for further details. Although specific set-aside provisions, NAICS codes, or funding details are not included, the work is confined to California and all activities are to be performed on-site along the designated stretch of SR 299.
