The B148 is a short B-road in the Essex town of Basildon. The road came into existence in the 1970s with the growth of the New Town.
The road starts at a GSJ on the A127 at Dunton Wayletts on the corner of town. It heads south along a dual-carriageway, passing the Dunton Technical Centre of the Ford Motor Company before the central reservation disappears. The road continues south through open country before bending left to a roundabout on the edge of the urban area, where the B1036 is met.
We now head east along West Mayne, a leafy New Town distributor running between housing estates, which are accessed via frequent roundabouts. Housing to either side is hardly visible at all. As we pass under a footbridge in Laindon it is obvious that the road was planned to be D2 but only the eastbound carriageway was built. After the next roundabout housing is visible and the road is D2 - but only for a short distance. We follow St Nicholas Lane, which does have side-streets, and it isn't long before we reach another roundabout where the road ends. Ahead is the A1235 and we also meet the A176 here.
