INVITATION FOR BID (IFB) FULL AND OPEN COMPETITION WITH HUBZONE PREFERENCE PROJECT NUMBER: ND NP THRO 204(1) PROJECT NAME: Buck Hill Road PROJECT DESCRIPTION: Buck Hill Road, also known as Route 204, is located in Billings County within Theodore Roosevelt (THRO) National Park (NP) in the southeast portion of the park near the South Unit, Medora, ND. The route is located in mountainous terrain at approximate elevation of 2,500 to 2,800 feet. It begins at the intersection of Buck Hill Road and South Unit Scenic Loop Road.

The main roadway rehabilitation includes pulverization of the existing roadway, placement of new roadway aggregate, and new hot asphalt concrete pavement and replacing existing guardrail with new guardrail. Additionally, this work includes constructing new paved ditches and installing concrete curb and gutter along most of the length of the roadway. This includes installation of several drainage inlets and culverts as well as new striping and signage. The deep subexcavation work includes removal of approximately existing unsuitable material to a 10 feet depth for a continuous 1,000 linear foot length of roadway and replacing with suitable material with geosynthetic reinforcement and installing subsurface drainage. A geotechnical report will be provided with the PS&E package.
