Description

The Madison to Norris project is located on the western part of the Grand Loop in Yellowstone National Park.  This 10 mile project addressed multiple deficiencies in pavement, drainage, alignment and safety. With larger recreational vehicles and busses traveling through this area, the existing narrow lanes posed a safety hazard. Additional seasonal traffic was also straining the capacity of the roadway with minimal pullouts and parking areas for visitor attractions. The project used native and non-invasive plants and restored natural habitats along the Gibbon River.  Materials from the existing roadway were reused when possible and were often used to create natural looking rock walls and cut slopes.
