Grafton Bridge

About

Grafton Bridge is a road bridge spanning Grafton Gully in Auckland, New Zealand. Built of reinforced concrete in 1910, it connects the Auckland CBD and Karangahape Road with Grafton. It spans about 97.6 metres (320 feet), rises 25.6 metres (84 feet) above the abutments to a height of around 43 metres (141 feet) over the gully. When the bridge was constructed, it contained the largest reinforced concrete arch in the world. The bridge is listed by Heritage New Zealand and on the IPENZ Engineering Heritage Register. In a 2006 poll of 600 alumni of the University of Auckland School of Engineering, the bridge was third in the list of New Zealand engineering achievements, after Manapouri Power Station and Black Magic. Since 2009 the bridge has formed a core part of the Central Connector public transport route between the CBD and Newmarket, and is closed to private vehicles except taxis during the day.
