First Aberdeen bus routes 1 and 2

Route 1 was created to replace the "Bridges" Aberdeen Corporation Tramways route in the late 1950s.^[1][2]

Route 2 was formerly numbered 21, it was renumbered in the 1960s.^[3]

Service 1A, which offered an express service from Robert Gordon University to the city centre, was withdrawn in March 2020. It was reintroduced on 20 February 2023.^[4][5]

The Bridges branding was lost after the introduction of new buses on the route.^[6][7]

Service N1 was introduced in 2025, linking the City centre to Danestone.^[8]

Routes 1 and 2 are shared between the Bridge of Don and Great Southern Road. Route 1 takes a clockwise route through Garthdee, while route 2 takes an anti-clockwise route.

The route has suffered from overcrowding between Union Street and Robert Gordon University with people at intermediate stops not being able to board at busy times.^[9][10]
