Outstanding Engineering - 2016 ACEC National Recognition Winners

ACEC 2016 National Recognition Award Winner:

Firm Name: Hanson Professional Services Inc.
Project Name: Alaska’s Glenn Highway Capacity Improvements
Project Location: Eagle River, Alaska
Client Name: Alaska Department of Transportation

With increased traffic expected to exceed the highway’s design capacity in the coming years, the project team was tasked with designing new lanes that will be used for both regular and high-occupancy vehicle traffic, reducing the grade on a steep approach to the northbound Eagle River Bridge, designing new bridges over the Eagle River, and creating new frontage roads.

Challenges included accommodating an existing gas pipeline and incorporating the new infrastructure within the existing right of way, especially with the highway’s challenging geometry and tight turns. The project was completed one year ahead of schedule, due to an accelerated concurrent design-build process that also decreased lane closures and delays.

This project is one of 151 being recognized by ACEC from throughout the nation and the world as preeminent 2016 engineering achievements. All 2016 winners—including 16 Honor Awards, eight Grand Awards and the prestigious “Grand Conceptor Award” for the year’s most outstanding overall engineering achievement—will be celebrated at the upcoming Engineering Excellence Awards Dinner and Gala, a black-tie event to be held Tuesday, April 19, at the Marriott Wardman Park Hotel in Washington, D.C., as part of the 2016 ACEC Annual Convention.
