A4074 road

The A4074 is a British A road and primary route from Caversham, Reading to Heyford Hill on the Oxford Ring Road. It takes a direct line across the Chiltern Hills to Benson, bypassing Crowmarsh Gifford. It then passes through Shillingford, bypasses Dorchester and passes through Nuneham Courtenay.

The road was designated in the 1980s, when the B479 between Caversham and Crowmarsh Gifford was renumbered. In 1990 the A423 from Crowmarsh to Heyford Hill was renumbered the A4074, and the road became the primary route between Reading and Oxford in place of the A329 along the River Thames. The short stretch of the Oxford Ring Road between Heyford Hill and the Hinksey Hill interchange was not renumbered A4074, and remains an isolated fragment of the A423.
