The B468 is described in the 1922 Road Lists as Northwood - Watford.
The road started on the A404 on the edge of Northwood. It headed north along the High Street and zigzagged along Green Lane before continuing north along Watford Road. After crossing the county boundary it skirted Oxhey Woods before bending sharply right. It ended under the railway viaducts on the A40 (later A411) in Oxhey, to the south of Watford.
The road has now been upgraded to Class I status and is numbered A4125.
