Blackhorse Interchange was a planned junction as part of the original proposals to dual the A30 between Honiton and Exeter in the early 1970s. The initial proposal was for a trumpet allowing freeflowing movements between the new road and the former A30, now B3174. By 1972 consideration was given to constructing the road as a motorway rather than as an all-purpose road. The design standards at the time meant the current proposal was unsuitable for a motorway as traffic leaving the motorway had to use the outside loop of a trumpet and the slip road had to be a dual carriageway. Therefore the junction was now planned in reverse to face the correct way and the slip road now ended at a roundabout.

Despite these changes and the recommendation to build the road as a motorway the project was cancelled. It was another two decades before the scheme was resurrected and by this time the road was now planned on a more southerly alignment which opened in 1999. The Pound Corner junction now serves the purpose of Blackhorse Interchange.
