The California Department of Transportation will accept bids March 16 for cleaning and painting inside the Randolph Collier Tunnel under Oregon Mountain.
The painting contract is estimated at $720,000. The project involves cleaning and painting concrete surfaces inside the two-lane, 1,886-foot tunnel in Del Norte County, about three miles south of the Oregon border.
The project includes cleaning and coating 122,100 square feet of concrete with an acrylic emulsion system. Cracks in concrete must be repaired before painting, and paint must be removed from concrete surfaces before repairs begin. The work must be completed within 130 working days.
The existing coatings contain lead; all debris produced when the existing paint system is disturbed must be contained.
The project also requires controlling potential sources of water pollution before they come in contact with storm water systems or watercourses.
Rugged Route
The tunnel, named for the powerful California state senator who shepherded the project, carries US Highway 199 (the Redwood Highway) under Oregon Mountain. The tunnel opened in 1963 after three years of construction.
The tunnel provided the first direct route from northwest Nevada to the Pacific Ocean. It also eliminated the route over the summit's 128 curves and hairpin switchbacks, and made the highway passable in snowy weather.
Reported by Paint BidTracker, a construction reporting service devoted to identifying contracting opportunities for the coatings community.
