Dunedin Southern Motorway

There is a half diamond interchange at Old Brighton Road (northbound on, southbound off) before the motorway climbs towards its highest point, crossing a ridge of Saddle Hill.A motorway extending south from the Andersons Bay intersection was first proposed from the late 1950s, when Dunedin, like other major centres in New Zealand, was experiencing rapid vehicle growth and a decline in public transport usage.A number of roads around the city were widened to four lanes, and the report recommended that investigation, design, and construction begin of the proposed southern motorway.This section began at the southern end of Kaikorai Valley Road at Burnside, and travelled south for 2.5 kilometres, dividing Green Island from Abbotsford.Earthworks were undertaken to allow for the construction of a four-lane motorway with northbound and southbound slip lanes extending from a future interchange with SH 87 at Mosgiel.It extended southwards from the Andersons Bay intersection, across King Edward Street on twin bridges to connect with South Road near the Glen.In 1989-1990 the Green Island motorway was extended northwards up Calton Hill past the Burnside Freezing Works to re-connect with SH 1 at Lookout Point.There were several delays in construction of this stretch due to the presence of mine workings that created major difficulties in the stabilisation of the land along the route.Stage 1 of the project upgraded the Caversham Bypass from the Glen to Barnes Drive to a four lane median divided highway, this involved a duplication of the South Road overbridge.
