WY NP YELL 15(2), Madison River Bridge

The project, titled WY NP YELL 15(2), Madison River Bridge, is located approximately seven miles east of West Yellowstone, Montana, within Yellowstone National Park in Wyoming, and encompasses a 0.36-mile corridor involving comprehensive transportation infrastructure reconstruction. The scope includes constructing a two-lane temporary traffic bridge and detour, removal of the existing bridge, installation of riprap scour protection, new bridge construction, stone masonry work, geotechnical ground improvements, parking area enhancements, and approach road reconstruction. All work must adhere to the Federal Highway Administration’s FP-24 Specifications for Construction of Roads and Bridges on Federal Highway Projects, with strict compliance mandated for structural concrete, reinforcing steel, structural steel fabrication and erection, expansion joints, and specialized bridge components such as elastomeric bearings and Yellowstone-style steel railings. Key material quantities include 1,000 linear feet of 36-inch steel pipe, 600 linear feet of 42-inch steel pipe, 195,000 pounds of reinforcing steel, 490,000 pounds of structural steel, 526 cubic yards of structural concrete for the deck, and 32 cubic yards of rock-face finished masonry. Temporary construction measures require a work bridge, shoring and bracing, and dynamic pile load testing for six piles, while environmental compliance dictates that all equipment and vehicles undergo a mandatory weed and mud inspection by Park personnel prior to entry into the National Park boundary. The project is scheduled for a tentative solicitation release in Winter 2027, with a fixed completion date set for Fall 2030, and an estimated value exceeding $20,000,000. It is procured under NAICS Code 237310 by the Department of Transportation’s Western Federal Lands Division, based in Vancouver, Washington, with no set-aside provisions applied. Contract administration and performance requirements include mandatory contractor quality control and assurance, sampling and testing protocols, construction surveying and staking, and detailed scheduling compliance. Special requirements extend to site management, including prohibitions against storing equipment or materials in buffer zones, the use of pilot cars marked with “PILOT CAR FOLLOW ME (G20-4)” signage and the contractor’s name, and adherence to Section 156 of the special contract requirements for minimum width specifications. The solicitation is currently in presolicitation status, with official documents expected to be posted on SAM.gov in Winter
