 Canterbury is by @-@ passed by the A2 London to Dover Road . It is about 45 miles ( 72 km ) from the M25 London orbital motorway , and 61 miles ( 98 km ) from central London by road . The other main road through Canterbury is the A28 from Ashford to Ramsgate and Margate . The City Council has invested heavily in Park and Ride systems around the City 's outskirts and there are three sites : at Wincheap , New Dover Road and Sturry Road . There are plans to build direct access sliproads to and from the London directions of the A2 where it meets the congested Wincheap ( at present there are only slips from the A28 to and from the direction of Dover ) to allow more direct access to Canterbury from the A2 , but these are currently subject to local discussion . In 2011 a third junction was constructed , linking the A28 to the northbound A2 ; this leaves just the A2 southbound exit missing , but since this would cut across the Park & Ride car park and meet the A28 at an already complicated junction , it is not expected to be added in the near term .
