The historic Great North Road was built using convict labour between 1826 and 1836 (this section south of Wollombi was completed in 1832). The road formed a link between Sydney and the Hunter Valley, including Newcastle. There are visible remnants of the original work in bridges, retaining walls and other structures along the way. The 'Convict Trail Project' has member groups involved in the conservation of historical remnants along the road. The Convict Trail Project and the NPWS have erected information signs at various points to illustrate the history. The Convict Trail Project has an excellent website for further reading.
