 The Harbour Highway, bypassing Larne, is dual carriageway, and includes a grade-separated junction with the A2 and provides a direct link to the Port of Larne.Beginning in 2012, a major upgrade project costing £133m was undertaken to upgrade the remaining single carriageway section between Coleman's Corner and Larne to High-quality dual carriageway and replace all major junctions with grade separated overbridges or LILO junctions to improve safety on a previously very dangerous road.In addition, the village of Ballynure, for many years a major bottleneck on the route, was bypassed as part of the part the scheme.
