Five of eight timber truss bridges added to the state government's conservation program can be found in the Hunter.
Transport for NSW announced on Tuesday it had removed seven bridges from its 2012 list and added eight others, including Beckers bridge at Gresford, Bulga bridge at Singleton, Cooreei bridge at Dungog, Gillies bridge near Rothbury and Junction bridge near Scone.
Of more than 400 timber truss bridges built between 1860 and 1936, 48 remain intact, with 39 managed by Transport for NSW.
"These bridges were ahead of their time when they were built, showcasing leading engineering practices, and connecting local communities to one another," Transport for NSW executive director regional and outer metropolitan Roy Wakelin-King said.
"Transport for NSW has worked closely with the Heritage Council of NSW to ensure those bridges with strong local ties remain protected and restored as necessary.
"We've reviewed the conservation list of bridges developed in 2012, with eight bridges being added to the list, while seven which did not meet the strategy objectives were removed.
"Conservation will ensure the retained bridges continue to provide safe access for all users, including pedestrians, cyclists, motorists, agricultural vehicles and freight."
