Historic Bridges: Management, Regulations, and Rehabilitation


Historic bridges represent a significant inventory of America's engineering heritage. Learn bridge typology and history. Discuss impacts on resources, avoidance of adverse effects, and alternatives and solutions. Explore how a collaborative team approach to rehabilitation projects benefits the regulatory and design process through interactive exercises. Discuss rehabilitation techniques that will meet engineering and historic standards. Review how to successfully navigate the requirements of the NEPA, Section 106, and Section 4(f) processes.

Evaluation Comments

“The seminar gave me valuable insight into the issues and process when working on historic bridges.”

“Clearly, succinctly covered an incredible amount of information on many aspects of historic bridges I need to know. I think this seminar went into as much detail as was reasonable, given the time, on material conservation, how materials erode/weather, and technical aspects of engineering.”

“The blending of engineers, historians, consultants provided for excellent variety of conversations, especially during the group exercises.”

“Very good examples of past projects [case studies] along with lessons learned, techniques, and things to watch for.”

“It met my expectations in the discussion of environmental requirements and the explanation and application of NEPA/Section 106/Section 4(f).”

“I found the collaboration exercises to be very beneficial because it gave the opportunity to put things into practice.”

“Going through the entire process was helpful. Group discussions were enlightening as well as a good way to have the group feel comfortable talking to each other.”

“The instructors’ experience with management plans and collaboration between engineers/historians/state/federal agencies provided great information on this topic.”

“Provided a methodology to move forward on historic bridge projects.”
