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 (142 feet) over the gully. When the bridge was constructed, it contained the largest reinforced concrete arch in the world. 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 during the day.
