Best of the Best: America’s Transportation Awards! (via FHWA Public Roads)

Best of the Best: America's Transportation AwardsAll across the country, State departments of transportation (DOTs) are hard at work repairing old bridges, widening and constructing new highways, improving sidewalks, and repaving roadways to keep America on the move. Tens of thousands of these projects, large and small, have a major impact on the lives of every American, whether they walk, drive, bicycle, or take public transportation to get around.

Accelerated Bridge Construction (via FHWA)

Time-Lapse Video of Keg Creek Bridge Replacement – Highways for LIFE – FHWA

This time-lapse video shows accelerated bridge construction (ABC) techniques being used by a local contractor with standard equipment to replace a three-span bridge on U.S. 6 over Keg Creek in Pottawattamie County, Iowa. The $2.7 million reconstruction project is a cooperative effort involving FHWA, the Iowa Department of Transportation and the Second Strategic Highway Research Program (SHRP2). This Highways for LIFE  demonstration project was also part of SHRP2 Renewal research which created standard bridge designs that can be adapted to a large number of bridge projects. The design scales ABC methods to typical projects so that the benefits of faster construction and advanced materials are replicated wherever possible. The goal is to make ABC techniques a standard part of bridge construction. In the Keg Creek demonstration, road closure was reduced from six months to two weeks. Continue reading
