B4505 Chesham - Boxmoor


Looking across Chesham from Eskdale Avenue

The B4505 is a cross-country route across the Buckinghamshire and Hertfordshire border.

The road starts in central Chesham, leaving the A416 just north of the St Mary's Way roundabout, and heads north up Bellingdon Road for a fifth of a mile. It then turns right into Townsend Road and a tenth of a mile later it reaches the A416 again. This short section is not signed as B4505, as its classification is rather odd, although it does appear on maps with this number.

After a fifth of a mile merged with the A416, the B4505 turns right at the Jolly Sportsman pub and climbs Eskdale Avenue. At the top of the hill the road turns left at a roundabout onto Lye Green Road. White Hill, that also meets this roundabout, is a shorter though steeper way to get to and from Chesham town centre. Leaving Chesham, Lye Green Road passes through open countryside before reaching Lye Green village.

Lye Green and the adjacent Orchard Leigh are passed through without any speed reduction: any houses being well spread out and back from the road. Half a mile after leaving Orchard Leigh the B4505 runs along the Bucks/Herts border, then veers right at the turn for Whelpley Hill to enter the latter county. A mile later the road reaches Bovingdon, a large village, entering it on Chesham Road. Mini roundabouts mark the village centre but the B4505 goes straight on along Hempstead Road.

After passing Boxmoor Golf Course the B4505 heads along a valley going down into Hemel Hempstead. It ends at traffic lights on the A4251 (former A41) outside the Swan Inn.


The B4505 was originally unclassified but gained its number in the early 1930s, with the exception of the separate section in Chesham.

There have been plans to declassify the road to get traffic out of Bovingdon. However, as traffic is almost entirely local, removing its status as a B road would do nothing, so it has kept its number.
