ITD Wins Trio of National Transportation Awards

The Idaho Transportation Department has won three national awards in the AASHTO President’s Transportation Awards, announced at the group’s annual meeting in San Diego on Friday, October 29. The American Association of State Highway and Transportation Officials (AASHTO) is the national organization overseeing all the departments of transportation from each state in the country. ITD replaced two concrete bridges carrying Interstate 90 traffic over Pennsylvania Avenue in Coeur d’Alene with one bridge. To limit the duration of impacts to the traveling public, the project used Accelerated Bridge Construction (ABC) methods, which simplified construction and reduced the amount of on-site concrete formwork required. The bridge abutments, piers, and girders were cast off-site in nearby Spokane while work proceeded at the site.
