Yellowstone National Park, Wyoming

Curvilinear alignment and retaining walls reduce the impact to the surrounding slopes and help the East Entrance Road remain true to its historic alignment. Weatherized steel guardrail blends into the natural colors present along the route.Stone guardwall accentuates the curvilinear alignment as the East Entrance Road enters Sylvan Pass. Widened and deepened ditches along the erosive cut slopes minimize rockfall hazards.

Honorable Mention: U.S. Route 212, Beartooth Highway, Cooke City, Wyoming Beartooth Highway curves at the base of a rock slope with evergreen forests and rugged mountains in the background. In the early 1930’s, Beartooth Highway was constructed as a long approach road to Yellowstone.

Award of Excellence: Lee Roy Selmon Crosstown Expressway Expansion, Tampa, Florida
Completed Photo

In areas with limited access, concrete segments were delivered over the completed portions of the elevated roadway. Maintaining traffic during construction is a benefit important to the future of expanding our national transportation corridors.Bridge technology was applied in a non-traditional manner to this congested urban corridor, resulting in bridges that utilize only 6’ of the existing median in order to add six lanes of capacity. Minimal right-of-way was required.Ridership on the elevated lanes have exceeded projections and significantly reduced congestion and commute times between eastern suburbs and Tampa, on both the tolled expressway and parallel US 60. Commuters’ drive time has been reduced by more than 50%.
