This project will consist of roadway resurfacing, restoration, rehabilitation, and reconstruction of approximately 4.9 miles of roadway on the CA FTNP/NPS YOSE 500(2) & 16(7) project in Yosemite National Park, Mariposa County, California.  Work is included on El Portal Road and Valley Loop Road (Northside and Southside Drives), and Sentinel Drive within Yosemite Valley. 

Principle work items include 22,000 tons of superpave hot asphalt concrete pavement, 24,000 tons of aggregate base, 18,000 cubic yards of roadway excavation, 7,000 cubic yards of subexcavation, 8,000 tons of surface course aggregate, and 3.8 miles of pulverizing.  Work also includes realignment of 2,000 feet of Northside Drive, roundabout construction at the Village Drive intersection, reconstruction of the Camp 6 and Camp 4 parking lots, drainage improvements, asphalt and aggregate trail construction, and utility work including waterline, sewerline, and electrical system installation.  Additional work items include 1,200 square yards of reinforced concrete pavement, 30,000 linear feet of concrete curb, 5,000 feet of granite curb, 2,800 linear feet of pipe culverts (CMP), and 50 stone masonry headwalls.

All of the work is occurring in cultural and natural resource sensitive areas.  Construction phasing and temporary traffic will be very important to minimize disruptions to park visitors throughout construction.  Temporary traffic control will need to accommodate vehicles, bicycles, and pedestrians.

It is anticipated this project will be advertised in June, 2016 with construction beginning in October2016 and extending through November 2017.

The estimated price range is between $12,000,000 and $16,000,000.
