Terminus of the B4 (foreground) on the B3 close to Jurby East
The B3 starts at a fork junction on the A17 just south of Andreas and heads west between fields. For much of the way, the road sits down between banks topped with gorse hedges, quite a common feature on the island, meaning that there is little to see. After crossing The Lhen Trench, the road enters East Jurby, and while there are a couple of roadside houses, most of this scattered community is hidden down side roads and drives. A sharp left hand bends sees the B13 continue ahead to meet the A10, coast road, and soon after, as the B3 curves back to the west, the B4 turns off to the left. The route now enters Jurby Village, a community which was largely created with the construction of the airfield in World War Two. It remained an RAF base until the 1990s, but is now a race track with industrial estate. The B3 skirts the northern edge of the village and soon ends at a T junction on the A10.
History
As originally numbered in the 1920's, the route was given the B7 number. It had been renumbered as the B3 by 1963, even though the B7 number was re-used a few miles away.
