District 1 - PA Flex Beam
Purpose: The project will validate a low-cost system for rapid replacement of deficient short-span highway bridges.
Maintenance - Project No: EO3134 WO 014
The Flex Beam bridge system uses modular, lightweight, full-span components prefabricated from a steel section and concrete deck. These components can be rapidly installed by small teams using light construction equipment. This bridge concept was created through collaboration between Lehigh and PennDOT engineers. A prototype bridge will be constructed and tested to assess constructability, service load performance, and strength. Details will be developed for the field-installed connections between components.
Create new BD standard for Flex Beam and update DM-4, Chapter 2 sections 2.6 & 2.7.
