Dunedin City Council have been widening parts of Portobello Road since the early 2000’s. This is primarily to create space for pedestrians and cyclists with additional width and realignment for road user safety.

The project consists of 16 separable portions, (SP’s), making it the largest roading package ever contracted by the Council. As this is one of two key tourist routes the project was a priority for the Council.

In April 2018 Fulton Hogan established on site at SP8, the first section to progress. The project consisted of bulk fill, rock sea wall (hand stacked), raising the road level to future proof against sea level rise, road widening from 6.5m to 11m, drainage improvements, surfacing works, line marking, pump station upgrades, installation of kerb blocks to create a separate shared path, and landscaping. The total length of the site was 2.6 kilometres.
