|This project was initiated and its purpose and need were defined in the mid/late 2000s. Early in the project, many primary engineering options were considered; some of the options were dismissed and some of them later became a part of the proposed alternative. Following project scoping (2011), a series of special environmental studies were completed and preliminary engineering was conducted (2012 –2016).|
The project is proposed to be constructed in two phases. The first phase of project construction will rehabilitate MP 75 to 77.7 (Placer River Overflow), and MP 81 to 90, and is anticipated to begin in 2018. Phase 2 will construct MP 77.7 to 81 and is anticipated to begin in 2020. Each phase is anticipated to take approximately two years to construct. Dates are projected and subject to change, based on availability of funding and other factors.
As Phase One includes two sections of roadway on either side of the Phase Two area, the entire 15-mile project corridor will be impacted by seasonal construction once Phase One has begun.
