The northern end of the B486, seen from the B488
The B486 is a short link in Tring, Hertfordshire. The route begins at the eastern end of the High Street, at a mini roundabout junction with the B4635, next to the Robin Hood Inn. From here it heads north along Brook Street, passing – all on the left – the fire station, the old silk mill, and a small area of parkland along the banks of the brook after which the road is named.
After passing the left-hand turn for Silk Mill Way our route becomes Wingrave Road and we enter the 19th-century settlements of New Mill and Tring Wharf, with older houses on our right and more recent residential development to the left. The B486 ends close to the end of the built-up area, at a roundabout junction with the B488 Icknield Way/Bulbourne Road and the unclassified Tringford Road.
The B486 used to be a part of the B488
The route that is today the B486 – the original B486 having been a much longer road, about five miles east of Tring – was once a part of the B488. At some time between 1978 and 1984 the start of the latter route was shifted to Tring Hill, west of the town, with the B488 reaching Tring Wharf via Icknield Way; in consequence, the Brook Road / Wingrave Road route was renumbered to become the B486.
