Historic wrought iron and steel bridges are being replaced at an alarming rate. Those that remain are often rehabilitated using inappropriate techniques or are downgraded for limited highway traffic or pedestrian use. Lansing Community College in Lansing, Mich., is using a PTT Grant to develop and provide training based on modern and historic technologies to address the national need for preservation expertise in preserving historic metal truss structures.

NCPTT awarded 12 projects, totaling $262,500, for preservation technology and training awards to universities, non-profit organizations, and state agencies.

More than $350,000 will fund research to protect America’s historic legacy as part of the National Center for Preservation Technology and Training’s PTT Grants program.
