Project Description

This 1-year, 8-month highway reconstruction project, which was awarded in November 2024 and will run through June 26, 2026,  includes a large and diverse scope of work within the contract period. An estimated 70-80 skilled operators and laborers will be necessary to accomplish this herculean project, including a night crew of 25-30 employees which work from April through October 2025. 

This reconstruction project involves moving and placing over 400,000 CY of blasted rock and 1,000,000 CY of excavation and unclassified excavation.  In all, an estimated 108,000 tons of gravel surfacing material will be hauled, primarily by Oftedal side dump trucks, and placed by Oftedal blade operators. 

The project also requires the installation of 15,000 LF of concrete reinforced pipe (RCP) and corrugated metal pipe (CMP). Subcontractors will assist with the installation of the concrete pipe, which includes approximately 300 LF of massive, 15′ x 16′ precast box culverts and 150 LF of cast-in-place 13′ x 13′ double run RCP, while Oftedal crews will install the CMP pipe, the largest of which is 72 inches.

During the project, three sections of US 385 from Paktola Reservoir south to Sheridan Lake will be closed intermittently during the following timeframes: April 28 through June 13, 2025; August 12 through Oct 17, 2025; and October 20, 2025 through March 6, 2026.
