The B1523 is a short B-road in the Northumberland town of Blyth. Except for the southern end the road was originally part of the B1327. This became the A1061 in the 1970s and then gained the B1523 number when that road was moved onto the present bypass.
The road starts at a roundabout on the A1061 and heads north across fields to reach a mini-roundabout just inside the urban area; this is where we join the pre-bypass A1061. We continue through the centre of New Delaval and bend sharply right to go over a level crossing on a freight-only railway line to reach a roundabout. We take the (unsigned) exit at two o'clock to cross another level crossing on a disused branch line. We continue east along Plessey Road before bending to the left and ending at a roundabout on the A193. Ahead is the B1327 into Blyth town centre.
