Sector

TRANSPORT

The two bridges are located on the Gladstone-Mt Larcom Road (Hanson Road) near Gladstone in Central Queensland. This road is a critical freight link connecting the Port of Gladstone to the network across the state and is a 25m B-double route. The Gladstone-Mt Larcom Road has an annual average daily traffic of 6,395 v/d with a 15% heavy vehicle component and is a principal cycleway network.

The bridges were designed and built by a non-Department Transport & Main Roads (DTMR) agency and DTMR has taken over custodianship of the structures. It was assumed that DTMR design codes and standards were not considered during design or construction and the design life of the structure is unknown.
