The Hexham Bridge is located at the junction of the Pacific Highway and the New England Highway and joins the two roads across the Hunter River. As a result of ongoing reliability issues and operating difficulties, CDMS Electrical Engineers was engaged by Roads and Maritime Services to provide electrical design and drawings for the automation upgrade of the bridge. This included electrical drawings and implementation of a PLC control system as per an approved functional specification. A touch screen type operator interface was configured to work in conjunction with the PLC program.
