Project Description:

This project will consist of roadway resurfacing, restoration, rehabilitation, and reconstruction of approximately 2.8 miles of roadway on the CA FTNP YOSE 14(5) & 219(2) project in Yosemite National Park, Mariposa County, California.  Work is included on 0.9 miles Wawona Road at the South Entrance, and 1.9 miles of Mariposa Grove Road from the South Entrance to the Lower Grove.  The estimated price range is between $5,000,000 and $8,000,000. The anticipated advertisement date is July 2016.  Construction is anticipated from October 2016 to May 2017.  Mariposa Grove Road will remain closed to the public during construction.

Principle work items include 10,000 tons of hot asphalt concrete pavement, 8,000 tons of aggregate base, 5,000 cubic yards of roadway excavation, 2,700 cubic yards of subexcavation, 2.7 miles of full depth reclamation (pulverizing), 4,000 square feet of rockery, 3,100 square feet of mechanically stabilized earth wall (with stone masonry facing) and 14,000 feet of concrete curb.  Work also includes roundabout construction at the intersection of Wawona Road and Mariposa Grove Road and drainage and site improvements.

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

Construction Duration: Construction is anticipated from October 2016 to May 2017. Mariposa Grove Road will remain closed to the public during construction.

The contracting range for this project is $5,000,000.00 to $8,000,000.00
