Donner_Pass_Plans.pdf

This document contains plans and specifications for a federal-aid highway project located on Donner Pass Road from I-80 Exit 174 in Soda Springs, California to the Truckee city limits. The project will rehabilitate the existing pavement and widen shoulders for bike lanes along 6.54 miles of the road. Selected pullouts will also be paved and improvements include drainage, signing, striping, and guardrail. The typical section will feature a 22-foot traveled way with 4-foot paved shoulders serving as Class II bike lanes. Significant construction quantities include 7,500 cubic yards of roadway excavation, 195 cubic yards of rock excavation, 12,000 cubic yards of aggregate base, and 20,000 tons of asphalt pavement. Other elements consist of 6,000 linear feet of guardrail and lump sum items for erosion control and traffic control. The cost range is estimated between $10 million to $14 million and construction duration is scheduled from spring 2020 to fall 2021.
