Electric trams were a common sight in early 20th century Salford, and had from 1901 replaced the earlier horse-drawn vehicles. A network of lines crossed the region, with coordinated services running through Salford, Manchester and the surrounding areas. Many served the new suburban housing and industrial developments built at the time, but in 1947 they were withdrawn in favour of more practical services – buses. The city is served by a complex road infrastructure, with connections from the M602 motorway to several major motorways, and A-roads including the A57 Regent Road and the A6042 Trinity Way. Salford City Council has also created both advisory and mandatory cycle lanes across the city.
