Description

The East Entrance project began 53 miles west of Cody, Wyoming and over a four year period improved a 7.0 mile section of road.  Major improvements included increased lane width, sight distances, and pullouts for improved safety, upgraded stormwater systems, and reconstruction of failing pavements.  Some materials were reused, much of the required rock was acquired nearby, warm mix asphalt was used and new retaining walls and slopes were constructed to look like natural surroundings.
