|Route outline (key)|
The A2012 was the number of the east-west road through the centre of Leatherhead.
The road started on the eastern side of town, where the A24 turned off its original route onto the eastern bypass. The A2012 headed into the town centre along Epsom Road before running along the High Street. It was crossed by the A245 at a staggered crossroads.
After crossing the River Mole the road left town along Guildford Road. It went under the railway line from Leatherhead to Dorking before climbing to its terminus on the A246 to the south of Fetcham.
The old A2012 followed the pre-bypass route through Leatherhead, made up of the old route of two separate roads.
When the road was inaugurated in the mid-1930s the bypass only covered the eastern side of town, taking A24 traffic away from the town centre. The A2012 number was given to the old A24 from there into the town centre, where it ended on the A245; this road then followed the pre-bypass A24 south to reach the other end of the bypass.
Shortly afterwards the bypass was extended west across the River Mole to take A246 traffic out of the town centre. The A2012 was therefore extended west along this road's old route, giving it its full length.
In more recent years Class I roads have been removed from the centre of Leatherhead. The majority of the ex-A2012 is now numbered B2122, although the old bridge has been bypassed and the High Street pedestrianised.
