Accelerated Bridge Construction

Accelerated bridge construction is making a name for itself in bridge replacement and now is a realistic option in bridge rehabilitation, proven by successful projects such as Minnesota’s Franklin Avenue Bridge and Pennsylvania’s State Route 30 Bessemer Bridge.

Bridge replacements and closures can force commuters into frustratingly long detours, block residents from convenient access to their homes and jobs, or delay life-saving emergency services. In a new HNTB Viewpoint, Chris Price, PE, national bridge practice leader, explains that continued infrastructure investment and alternative construction methods can aid faster project delivery. As an example, by constructing as much of a new bridge as possible offsite, such accelerated techniques can lead to speedier replacement or rehabilitation of workhorse bridges to reduce mobility impacts and user costs.

Owners who develop robust ABC programs often enjoy greater support from their communities, their state legislatures and even Congress. According to the Federal Highway Administration, several states are beginning to create policies for using or potentially using ABC techniques in their project development policies.

HNTB has been at the forefront of the ABC trend since it began in 2006. The firm worked with the Transportation Research Board and the American Association of State Highway and Transportation Officials on a six-year project that resulted in the Strategic Highway Research Program Report S2-R04-RR-2: Innovative Bridge Designs for Rapid Renewal: ABC Toolkit. The report includes national ABC design standards, design examples and construction specifications to guide public agencies on implementation.

HNTB also has a growing track record of involvement in successful ABC projects, including:
