Scotchwell roundabout is situated at the southern end of the Haverfordwest bypass, at a point some 100 m west of Narberth Road railway bridge on the eastern side of the town. All three arms are sections of the A40. The bypass itself heads northward from here; the road running eastward is the "classic" route of the A40 towards Narberth, while that joining from the west is part of the A40 loop through Milford Haven town. The latter section, constructed at the same time as the bypass and roundabout, follows an alignment a little to the north of the A40's original eastward route out of Haverfordwest past the railway station on Cartlett Road.
The junction is named after the nearby Scotchwell House, a grade II listed building which was itself named for a local spring known as the Scotch Well.
