Maryland Demonstration Project: Bridge Replacements on MD 28 and MD 450, Frederick County and Anne Arundel County

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 Maryland State Highway Administration (MDSHA) was awarded a grant totaling 20 percent of the total project construction cost (or $717,157), making this a 100 percent federally funded project.  The grant was awarded because the project was intended to demonstrate the use of proven, innovative technologies to deliver two rural bridge replacement projects in an accelerated schedule so as not to impact school bus routes. This report documents the MD 28 over Washington Run and MD 450 over Bacon Ridge Branch bridge projects, both single span bridges carrying two-lane, two-way roadways.

This report summarizes the practices employed for these projects, including the use of prefabricated bridge elements and structures (PBES), incentive contracting, and construction within full roadway closures and detours. The use of these technologies decreased estimated construction time from 15 months for similar typical bridge replacement projects to 3 months (only 2 months of roadway closure).

While the full roadway closures and subsequent detours significantly increased user delays and fuel consumption on a daily basis, the drastically reduced construction time and great savings in MOT and construction phasing resulted in a project savings of approximately $1.49 million (or approximately 32 percent of the total project costs) of the MD 28 project alone. Because of the success of this project, MDSHA is applying lessons learned and have already taken steps on other projects to further utilize PBES construction practices to save time and money.
