Site work and paving for a mixed-use development in Dinosaur, Colorado. Completed plans call for site work for a road / highway; for paving for a road / highway; bridge / tunnel; water / sewer project; sidewalk / parking lot; and sidewalk / parking lot.

PROJECT DESCRIPTION: The Central Federal Lands Highway Division (CFLHD) of the Federal Highway Administration (FHWA), in cooperation with the National Park Service (NPS) is proposing to rehabilitate (3R) the pavement and curb conditions for Harpers Corner Road within the Dinosaur National Monument. The project is located in Moffat County near Dinosaur, CO and will consist of rehabilitating approximately 14 miles of the road and one (1) parking area. Harpers Corner Road needs rehabilitation due to deterioration that is typical of aging pavements and due to several subgrade failures. SCOPE OF THE WORK: The project scope is rehabilitation of existing roads, pullouts and parking areas so that visitors can continue to safely access park destinations. The existing pavement along Harpers Corner Road is generally in moderate condition with several moderate to high severity subgrade failures. The existing posted speed along the route is 45 mph. This roadway is classified as an NPS Class 1 roadway; a principal park road/rural parkway with one lane in each direction. The existing roadway is paved and varies from 22 to 30 feet in width along the entire 14 miles with an approximate 2% normal crown and superelevation and corner widening, as needed on curves. Existing drainage is adequate with the exception of one subgrade failure where a new culvert is proposed. The asphalt curb and gutter is completely buried in several locations and overrun with vegetation and debris on others. Guardrail is generally in good condition but will be replaced to be meet current MASH requirements. The project will be split into a base schedule encompassing 4.33 miles, and 2 options, encompassing 2.73 miles and 7.06 miles. It will require minor widening where the existing width is less than 24 feet, as well as the addition of minor drainage improvements and concrete curbs. Improvements also include embankment, full-depth reclamation, asphalt concrete pavement, guardrail, concrete curb, culverts, gates, ADA improvements, pavement markings and subexcavation. The project will be constructed under temporary single lane closures requiring temporary traffic control. All work occurs within environmentally sensitive settings which will require best management practices and restrictions to protect identified resources. ESTIMATED COST RANGE: The project is between $10,000,000 and $20,000,000. TECHNICAL QUESTIONS REGARDING THIS SOLICITATION WILL NOT BE ACCEPTED AFTER 4 P.M. ON DECEMBER 08, 2022 Questions can be submitted to CFLContracts@dot.gov. *The value for this project is based on a financial range. The value is listed as the highest possible cost from the range provided by a stakeholder or official project document.
