Yellowstone National Park 2023 road improvement projects
• $216 million invested to improve safety, access and experience on park roads
Addressing the maintenance backlog is part of the National Park Service’s core mission to preserve national parks and provide a world-class visitor experience. Yellowstone has an asset inventory totaling $4.1 billion, with an estimated $1 billion in deferred maintenance and repairs associated with this inventory. The park also has an estimated $54 million in annual routine maintenance requirements. To further Yellowstone’s investing in inf
1. Lewis River Bridge
Location: Nearly 10 miles north of the South Entrance on the South Entrance Road
Access: Beginning summer 2023
Improvements: The project
2. Old Faithful to West Thumb
Location: Grand Loop Road between Old Faithful and West Thumb
Access: Beginning summer 2023 until fall 2023, expect up to 30-minute delays along this segment of road while roads are open to wheeled vehicles (May-Oct.31).
Improvements: This project includes the rehabilitation of 22 miles of the Grand Loop Road between Old Faithful and West Thumb, one of the most heavily traveled road corridors in the park. Construction will include repaving the full 30-foot-wide roadway segment, which was last repaved in 1987 and has deteriorated due to heavy usage and winter weather conditions. Additionally, guardrails, culverts and other drainage structures will be replaced to enhance visitor safety. This project costs $43 million and is funded through the Great American Outdoors Act Legacy Restoration Fund.
3. Yellowstone River Bridge
Location: Near Tower Junction along the Northeast Entrance Road
Access: Beginning summer 2023
Improvements: This project includes the replacement of the structurally deficient Yellowstone River Bridge built in 1963. A new 1,285-foot-long, 175-foot-high steel girder bridge upstream will replace the existing 604-foot-long bridge to preserve year-round access to/from the Northeast Entrance and communities of Silver Gate and Cooke City, Montana. New pullouts, paved parking areas, and dedicated route across the new bridge will increase access to trails, fishing and viewpoints. The Yellowstone River Picnic Area will be enlarged to accommodate increased visitor use. This project costs $118 million and is funded through the Great American Outdoors Act Legacy Restoration Fund.
4. Northeast Entrance Road (Flood Recovery)
Location: East of Tower Junction between Lamar Canyon and the Northeast Entrance
Access: Beginning early summer 2023 until fall 2023, expect up to 30-minute delays. The Northeast Entrance Road is open year-round to wheeled vehicles. Night work will occur (without overnight closures).
Improvements: This project includes the completion of work to address flood-damaged areas of the road between Lamar Canyon and the Northeast Entrance. Construction will include completion of a two-lane realignment in Lamar Canyon, paving a second lift north of the Trout Lake Trailhead, stabilization of streambanks adjacent to the road, work in the Pebble Creek Campground and Warm Creek Picnic Area. Additionally, some guardrails, culverts and other drainage structures will be replaced to enhance visitor safety. This project costs $25 million and is funded through the Emergency Relief for Federally Owned Roads Fund.
