Alaska's last link: Upgrading the final segment of Seward Highway in Alaska presented some geotechnical dilemmas. The site originally proposed for a new bridge had to be changed, but the project was completed on time
Article Abstract:
The last section of the Seward Highway in Alaska was challenging to design and built. The highway is a major transportation corridor for business and recreation and is the only land link for certain communities. There were many constraints and the project involved improving a section of a shoulderless road and bridging a stream with difficult foundation conditions. The new Canyon Creek Bridge features seven prestressed concrete spans and is on a curve around 95 ft above the canyon floor.

Wyoming DOT nails down roadway project in Snake River Canyon
Article Abstract:
A section of US Highway 26/89 through the Snake River Canyon is being reconstructed in multiple phases. A two-tiered soil-nail system supporting a mechanically stabilized earth (MSE) wall is being utilized to keep traffic flowing to Jackson Hole, WY. The system is characterized by a high lower soil-nail wall supporting a foundation for the MSE wall. Moreover, the upper soil-nail wall ranges between 4 and 6.7 m.
