PROJECT DESCRIPTION: The CA PRA LABE 10(1), Main Road project is located approximately 13 km south of Tulelake, California within the Lava Beds National Monument. The purpose of this project is to rehabilitate, restore, and resurface (3R), up to approximately 28.8 kilometers (km) (17.9 miles) of Main Road, from the northeastern boundary with the Tule Lake National Wildlife Refuge to the southern boundary with the Modoc National Forest. All existing paved pull-outs, parking areas, and overlooks will also be included, and the current unstable cinder road shoulders will be rehabilitated to improve safety and reduce extensive maintenance. The project plans utilize metric units. The project is broken up into a base Schedule A with three options (Option V, Option Y, Option Z). Schedule A includes 24.60 km of Main Road as well as the spur roads and five parking areas. Option V includes an additional 3.65 km of Main Road and one parking area. Option Y includes 0.53 km of Residence Spur Road, and Option Z includes 0.04 km of the Facility Maintenance Road and parking area. This project includes 28.8 kilometers (km) (17.9 miles) of typical 3R roadway with parking lots. The project also includes minor widening where the existing width is less than 24 feet (the existing roadway varies in width from 20 to 26 feet) and superelevation improvements. Minor drainage improvements and concrete curb and sidewalk work are also included in this project.

SIGNIFICANT QUANTITIES: 20402-0000 Subexcavation:1,400 m3 30306-2000 Pulverizing, 100mm depth: 162,300 m2 30306-2500 Pulverizing, 125mm depth: 69,500 t 40201-4700 Hot asphalt concrete pavement, Hveem test, class B, grading C or E: 55,500 t 63506-0500 Temporary traffic control, flagger: 5,600 Hour ANTICIPATED SCHEDULE: It is anticipated this project will be advertised in October 2021. Construction is anticipated between March 2022 and November 2023. ENGINEER’S ESTIMATE: The proposed project is estimated at a cost between $15 million and $25 million. MISCELLANEOUS: Roadway is open from March to November each year. No pulverization or paving can occur at the Cave Loop caves during the maternal bat season (July – September). All Option W work must be kept within the roadway prism due to potential archeological sites. Construction phasing will be implemented for this project: Do not close more than one minor road at one time. Complete all construction through the prime coat on one road before closing another road. Do not close more than 2 pullouts or parking areas at one time, including pullouts and parking areas with stockpiled material. Provide alternate one-way traffic on major roadways during construction operations. Open to two-way two lane traffic at the end of the day. Limit the exposure of pulverized material (primed or unprimed) to not more than 2 kilometers. The distance between the pulverizing operation and the first lift of asphalt paving will not exceed 2 kilometers.
