TRUCK CLIMBING LANE
The Interstate 80 Colfax Truck Lanes Project includes widening the shoulders to create a 12 foot wide truck climbing lane on eastbound I-80 in Placer County. This project is more than 66 acres and has lasted for over two years. Widening the road and constructing the climbing lane has required extending 13 culverts, installing 13 precast concrete headwalls, and sealing the interior of thirteen culverts with cast-in-place epoxy.
Tully Consulting Group wrote the Stormwater Pollution Prevention Plan for this project in May of 2016, and has been providing weekly site inspections, oversite inspection, Water Pollution Control Manager Services as well as Rain Event Inspections and monitoring since the project broke ground (read more).
