TranSystems has extensive experience working with projects involving historic bridges and shepherding them through the Section 106 and 4(f) processes. Our historians meet the Secretary of the Interior’s qualifications for history and architectural history and are very well qualified to conduct this effort and prepare Historic American Engineering Record (HAER) documentation for bridge replacements.
TranSystems was selected by the National Cooperative Highway Research Program (NCHRP) to prepare national guidelines for how to decide to replace or rehabilitate historic bridges. These guidelines have recently been unanimously endorsed by AASHTO’s subcommittee on bridges and have been published by AASHTO. We understand historic bridge programs and are up-to-date on the approaches used to mitigate historic bridge replacements, including HAER documentation.
Our historians and engineers have worked with state departments of Transportation on statewide historic bridge inventories and are currently working on historic bridge management plans that will be used to streamline the Section 106 and 4(f) processes for projects involving selected historic bridges.
