ONE of the most significant bridges in the Upper Hunter is closed due to damage.
Allan Bridge, located between Glenbawn and Segenhoe, is believed to have been damaged early on Saturday.
Staff from Upper Hunter Shire Council investigated and closed the bridge and Allan Bridge Road.
Police also attended the scene.
A specialist bridge assessor inspected the bridge on Tuesday, however, further structural investigation needs to be undertaken to determine the severity of the damage.
Council has a load limit on the bridge to preserve the structure.
Those travelling in the area are advised to use Broad Crossing or the Pages River Crossing, both on Glenbawn Road, while Allan Bridge is closed.
Of the five timber heritage bridges in the Upper Hunter Shire, Allan Bridge is considered the most significant.
It is a unique structure as it is one of two known Trussed Cable Suspension bridges in NSW capable of carrying road traffic.
Constructed in 1937, the Allan Bridge was washed away in 1955 and reconstructed at a site further downstream.
A major upgrade to the bridge supports and abutments was undertaken in February 2015, and the latest repairs and maintenance occurred in June 2016.
