|Route outline (key)|
It starts as the westward continuation of the A75 when that road is crossed by the A77 to the east of Stranraer town centre. The road heads west along London Road and soon runs into Hanover Street which becomes one-way westbound.
The one-way system ends at a mini-roundabout where the A718 is crossed. This actually marks the original eastern end of the B737 as the A-roads in Stranraer (which have hardly changed since 1922) did a perfectly good job of moving traffic around town. Even now there is no eastbound route of the B737 comparable with the westbound one-way roads. However, local traffic in the town centre does not usually worry about what road it is using.
After crossing the A718 the B737 climbs to the west along Sun Street. It levels out and continues along Leswalt High Road before ending soon afterwards at a T-junction back on the A718.
