Once in Cambridgeshire, the topography changes from undulating hills to flat agricultural and fenlands, round the villages of Melbourn and Foxton (the road going over a level crossing adjacent to Foxton railway station), through Harston and up to the M11 motorway at junction 11, near Cambridge. A10 traffic is signposted to travel north on the M11, skirting round the top of Cambridge on the A14; however, the former course of the A10 turns into the A1309 and heads for the city centre. The original A10 went through the heart of the city, past the major colleges along King's Parade, before turning north-east at Midsummer Common.
