Summary

Caltrans District 3 told Colfax council that the Blue Canyon pavement rehabilitation will be awarded to the low responsive bidder around March with construction likely in June–July. The multi‑segment project includes truck climbing lanes, two bridge replacements and median/guardrail upgrades.

Sean Shaw, Caltrans District 3 project manager, told the Colfax City Council on Feb. 11 that the agency has received multiple bids for the Blue Canyon pavement rehabilitation project on Interstate 80 and expects to award a contract to the lowest responsive bidder in March 2026 and finalize the contract in April. Shaw estimated contractors would mobilize in June or July and said the overall program could require about three construction seasons.

Shaw said the work covers three noncontiguous locations: near Crother Road to the Weimar Crossroad Undercrossing, Maggra Overhead Bridge to Gold Run Overcrossing, and the Blue Canyon Undercrossing to Putts Lake Undercrossing. He described project elements including replacement of two bridges (Weimar Overcrossing and the Blue Canyon Undercrossing), construction of 12‑foot truck climbing lanes to improve freight mobility, replacement and upgrading of metal beam guardrail to more durable concrete barriers, and selective sound walls to reduce impacts for nearby residents. Shaw said Caltrans anticipates an environmental finding consistent with a mitigated negative declaration and noted plan addenda may be issued during construction.

Council members pressed Caltrans for more precise limits and staging; Shaw said exact linear extents and staging details will be provided once plans are released with the bid package and offered to forward plan links for public posting. Shaw also described how crash data and truck volumes inform priority rankings for upgrades and said the agency will consider truck traffic in designing median improvements.

There was no council action required on the presentation; Caltrans will return with more detailed plans and links to the final bid documents when available.
