The B569 is a largely rural B-road in the south Midlands.
It starts at traffic lights on the A5028 (former A6) to the north of Rushden town centre. It heads southwest past Spencer Park and soon crosses the A5001 at traffic lights.
The road now leaves Rushden behind and crosses the Midland Main Line to enter Irchester. It zigzags along a short section of High Street (which also exists to the north as an unclassified road) before reaching a mini-roundabout on the western edge of the village. Here the B570 continues ahead and the B569 turns left.
About a mile later the B569 enters Wollaston. It zigzags through the village streets before reaching London Road and an unusual junction where westbound traffic has to TOTSO left but eastbound traffic has the through route. This marks the original western end of the B569, where it ended on the A509. However, the A-road now bypasses the village so the B569 continues south along the pre-bypass route to end at a T-junction on the A509 on the edge of Strixton.
