The document outlines the preliminary plans for the Sun River Bridge Replacement project under the federal Montana FLAP BOR 2980(1) initiative. The project's purpose is to enhance infrastructure in Teton and Lewis and Clark Counties, focusing on bridge construction, drainage, and road grading. Key components include a 0.33-mile project length and the incorporation of erosion and drainage controls, ensuring compliance with Federal Highway Administration specifications. The construction includes Mechanically Stabilized Earth (MSE) walls, guardrails, and other essential structures aimed at improving safety and access.
The plans detail various operational aspects such as surveying controls, engineering designs, and environmental safeguards, including wildlife-friendly features. The document emphasizes coordination with local authorities and proper construction standards to mitigate ecological impacts. Overall, the project signifies federal investment in regional infrastructure, enhancing mobility and safety while adhering to environmental guidelines.
The Western Federal Lands Highway Division is soliciting bids for the Sun River Bridge Replacement project, identified as MT FLAP BOR 2980(1) under Solicitation No. 69056724B000016. The project involves constructing a new three-span bridge and approach roadways in the Helena-Lewis and Clark National Forest. Additionally, an optional task involves the removal of the existing bridge and decommissioning of access roads. Due to potential snow cover, bidders are encouraged to inspect the site in the fall. All technical inquiries must be emailed to the specified address, while general inquiries can be directed to the office contact. The project is subject to a special weed inspection requirement for sourced materials. Relevant solicitation documents will be available in late fall 2024, with notifications through the SAM website recommended. This project aligns with federal RFP processes, emphasizing completion of public infrastructure improvements while adhering to environmental guidelines.
The MT FLAP BOR 2980(1) project involves replacing the Sun River Bridge located in Montana's Helena-Lewis and Clark National Forest. The project consists of constructing a new 462-foot precast-post-tensioned girder bridge with a concrete deck, situated 200 feet downstream of the existing steel truss bridge. It requires the building of new embankments and MSE wall approaches, with gravel surfacing for the approaches and concrete for the bridge. The project, estimated to cost between $10 million to $20 million, will take place over a length of 0.36 miles with a tentative completion date set for Fall 2026.
Key activities include site preparation, construction surveys, soil erosion control, earthwork components such as excavation and embankment, and installation of various bridge features and safety structures. The proposed work may also involve demolishing the existing bridge upon the new structure's completion. This RFP outlines the project's considerable engineering and construction tasks, emphasizing environmental controls and quality assurance throughout the project duration. The document serves as a structured outline for potential contractors regarding the project specifications and requirements necessary for the successful completion of the bridge replacement.
The document pertains to the Sun River Bridge Replacement project under the MT FLAP BOR 2980(1) program.
