The Roads and Traffic Authority (RTA) is proposing to upgrade the Pacific Highway between Brunswick River to Yelgun, in northern NSW. The proposal includes the duplication of the Brunswick Heads Bypass and the construction of a new dual carriageway between Brunswick River and Yelgun. This environmental impact statement (EIS) examines and assesses the potential environmental impacts of the proposal. The proposal is approximately kilometres long. The new highway would consist of dual carriageways with two travel lanes on each direction. The carriage ways would be separated by barriers or a median of variable width. The proposal would commence just north of Saddle Road and would include constructing a second carriageway parallel to the new Brunswick Heads Bypass. There would be an interchange approximately 700 metres south of the Brunswick River to cater for vehicle movements to and from Brunswick Heads.
