Auckland's first tram line, from the CBD to Ponsonby via Karangahape Road, opened on 24 November 1902. As the system grew, it facilitated the expansion of Auckland's built-up area in two ways: in an intermittent linear pattern to the west and south along the railway line, and in a more continuous manner along the main routes. The demand for more living space from people who had been confined to the crowded downtown area coupled with an affordable and reliable transport network led to the creation of many of Auckland's original suburbs, along Great North Road, New North Road, Sandringham Road, Dominion Road, Mt Eden Road, Manukau Road and Remuera Road, forming a new arc of suburban development by 1915.
