Caltrans proposes to enhance and preserve the useful life of the existing pavement and to improve the ride quality on eastbound (EB) I-80 in Placer County between PM R26.5 and 55.1 by grinding and overlaying the mainline. Operational improvement of the general-purpose lanes will be accomplished by constructing EB truck climbing lanes at three locations. To accommodate the truck climbing lanes, the roadway would be widened and two structures, the Blue Canyon undercrossing (UC) (Br.#19-0115R) and Weimar overcrossing (OC) (Br.#19-0082), would be removed and replaced with wider structures. Several entrance and exit ramps would also be reconstructed with the latest signing/striping standards for vehicles to properly merge into the new truck lane. Existing Traffic Management Systems (TMS) and Safety and Intelligent Transportation Systems (ITS) elements would be relocated and upgraded to current standards to actively manage recurrent and non-recurrent traffic congestion. All Metal Beam Guardrails (MGBR) would be replaced with Midwest Guardrail Systems (MGS); median concrete barriers, drainage, lighting, sign panels, and fiber optic would be upgraded as needed; and wildlife crossing conflicts would be addressed with the construction of a wildlife crossing.
