Foreword

The purpose of the Highways for LIFE (HfL) pilot program is to accelerate the use of innovations that improve highway safety and quality while reducing congestion caused by construction. LIFE is an acronym for Longer–lasting highway infrastructure using Innovations to accomplish the Fast construction of Efficient and safe highways and bridges.

Specifically, HfL focuses on speeding up the widespread adoption of proven innovations in the highway community. "Innovations" is an inclusive term used by HfL to encompass technologies, materials, tools, equipment, procedures, specifications, methodologies, processes, and practices used to finance, design, or construct highways. HfL is based on the recognition that innovations are available that, if widely and rapidly implemented, would result in significant benefits to road users and highway agencies.

Although innovations themselves are important, HfL is as much about changing the highway community's culture from one that considers innovation something that only adds to the workload, delays projects, raises costs, or increases risk to one that sees it as an opportunity to provide better highway transportation service. HfL is also an effort to change the way highway community decisionmakers and participants perceive their jobs and the service they provide.

The HfL pilot program, described in Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA–LU) Section 1502, includes funding for demonstration construction projects. By providing incentives for projects, HfL promotes improvements in safety, construction–related congestion, and quality that can be achieved through the use of performance goals and innovations. This report documents one such HfL demonstration project.

16. Abstract

As part of a national initiative sponsored by the Federal Highway Administration under the Highways for LIFE program, the Virginia Department of Transportation (VDOT) was awarded a $600,000 grant to demonstrate the use of proven, innovative technologies for accelerated bridge removal and replacement. This report documents accelerated bridge construction (ABC) techniques used to remove, widen, and replace the superstructure of the U.S. 15/29 bridge over Broad Run over three weekends.

This report describes the existing bridge and the materials and methods used to widen the three-span bridge and replace the superstructure. Prefabricated superstructure segments, four per span, were used to simplify and expedite construction. Under conventional construction, the impact of this project on the traveling public was estimated at 100 days, but with the use of accelerated construction techniques, the impact was reduced to three weekend closures.

Using ABC techniques added approximately $260,000 to the initial construction cost of the project. However, a more comprehensive economic analysis including user cost savings shows that the project saved road users an estimated $2.16 million or about 65 percent over conventional construction practices. Because of the success of this project, VDOT plans to use ABC techniques on future projects.

Notes:
  1. The primary metric (SI) units used in civil engineering are meter (m), kilogram (kg), second(s), newton (N) and pascal (Pa=N/m2).
  2. In a "soft" conversion, an English measurement is mathematically converted to its exact metric equivalent.
  3. In a "hard" conversion, a new rounded metric number is created that is convenient to work with and remember.

Acknowledgments

The project team would like to acknowledge the invaluable insights and guidance of Federal Highway Administration (FHWA) Highways for LIFE Team Leader Byron Lord and Program Coordinators Mary Huie and Kathleen Bergeron, who served as the technical panel on this demonstration project.
