Development of MASH TL-4 and TL-5 Bridge Guardrail for Replacement of Historic Bridge Rail

The replacement of bridge structures that have historic concrete railings often results in an adverse effect determination under Section 106 of the National Historic Preservation Act of 1966. When this occurs, KYTC is obligated to mitigate the adverse effect. Mitigation is a complex process that requires the Cabinet to develop a Memorandum of Agreement (MOA) that discusses why a feature has historic value, project impacts, parties the responsible federal agency has consulted with, and a mitigation plan. KYTC wants to design a concrete bridge rail design that complies with MASH TL-4 and TL-5 standards which can reduce the likelihood of Section 106 adverse effect determination. Developing a Section 106—compliant concrete railing design will reduce the number of adverse effect determinations, lower mitigation costs, and accelerate project delivery timelines.
