The sea-side option will create a 5m wide corridor between the harbour and the railway line. This enables the creation of a higher standard facility than the possible road-side options. As it is separated from vehicle traffic it will also be safer and more attractive for new users compared to other options.
Another benefit of the sea-side option is a new rock seawall that will protect the rail line from the risk of erosion and damage from storm surges, and also provide a vital access route for emergency vehicles in an emergency where SH2 is blocked – such as a landslide caused by a major earthquake. The road-side options would not have created this additional benefit.
The creation of a coastal path is also a key link in The Great Harbour Way/Te Aranui o Pōneke, a walking and cycling route around Wellington Harbour, from Fitzroy Bay in the east to Sinclair Head in the west. The completion of this publicly accessible coastal path will create recreational, cultural and tourism opportunities.
