These maps were updated in 2012 with funding from Central Bedfordshire Council, however circumstances on the ground are always changing...
In Hertfordshire the Icknield Way trail passes through Letchworth, Britain’s first garden city. Ebenezer Howard, the originator, took the advantage of both town and country and sought to blend them into a new style settlement.
The riders route has been added to Bing Maps, and the Waymark Trails - Equestrian route, and the mountain biking route. The interactive Map enables zooming into the Explorer 25,000 OS map scale. If any errors are identified, let us know - contact.
A review of all Icknield Way roadside signage was completed in late 2012. Hertfordshire CC corrected and supplement the signage early in 2013.
Between Pirton and Ickleford the route follows the Hambridge Way a wide and well surfaced section of the route.
Between Ickleford and Letchworth the routes crosses the East Coast mainline railway at Cadwell. Equestrians are required to follow the road under a very narrow bridge on a bend. In 2015 Herts CC installed a novel arrangement that illuminates warning road signs either side of the bridge once a rider (or walker) presses a button. Herts BHS are lobbying for a safer off road route.
Cyclists can follow the same riders route, or follow the off road Icknield Way walkers route to cross the railway on a footbridge. The footbridge includes a channel to wheel the bike up/down the steps
This rather old leaflet give details of the Icknield Way riders route: Countryside Commission Leaflet 2 Telegraph Hill, Hertfordshire to Great Chesterford/Cow Lane, Essex (~7MB file). The route described has been changed to take advantage of the new permissive bridle/cycleways to the east of Letchworth.
