Devonshire House

Devonshire House (also known as Devonshire Inn) is the name used by the National Highways for the Upottery end of the A303. It is a simple T-junction, although modified to take into account the high levels of traffic at this junction. At one time the A30 remained primary after the junction, but this status was revoked in the 1980s.

The A303 here was originally numbered B3170.

The junction is named after Devonshire House Farm, now largely known as Devonshire Inn Farm.

Upgrades

Proposals to dual the A30/A303 between Honiton and Marsh were first made in the late 1980s. Early plans showed the junction at Devonshire House as a dumbbell but this was soon changed to a large at-grade roundabout. The scheme remained on the cards until 1997 when a change of government put it on hold and later cancelled it in favour of upgrading the A358 instead.

In 2016 Devon County Council promoted a scheme for a single carriageway of mainly S2+1 standard between Honiton and Devonshire House. The junction would remain a T-junction and would be enlarged to include a central refuge. Following feedback from a public consultation the current proposal in early 2017 is now for the junction to become a modified trumpet.
