Cudgen Road Tunnel

The Cudgen Road Tunnel is a twin-tube road tunnel that forms part of the Pacific Motorway (M1) located near Stotts Creek in the Tweed Valley of New South Wales, Australia. The twin 134 m tunnels are illuminated inside with northbound traffic using one tunnel and southbound traffic in the other. The tunnels pass under the Cudgen Road and the Condong Range.

Features
It was built by Abigroup as part of the Yelgun to Chinderah upgrade of the Pacific Highway, opening on 4 August 2002. It was jointly funded by the New South Wales and Federal governments. It is the first tunnel to be built as part of a rural road project in NSW.

This alignment of the Yelgun to Chinderah motorway was aimed at avoiding the loss of prime cane land, avoiding flood-prone areas and preserving important local animal habitat. The best route was through the Condong Range. A tunnel was chosen instead of a road cutting because it was sympathetic with the surrounding environment by removing the visual impact of a road cutting.
