MAMMOTH HOT SPRINGS, WY – There will be four major road improvement projects in Yellowstone National Park in 2023. All four projects will cause delays. The four projects are, Lewis River Bridge, Old Faithful to West Thumb, Yellowstone River Bridge and Northeast Entrance Road
The National Park Service (NPS) began the Old Faithful to West Thumb and Lewis River Bridge project simultaneously in 2022 to complete both projects in a three-year window. Otherwise, impacts to visitors would have occurred over four to five years.
