In 1997, Sustrans built the first section of the Witham
cycle path, which will eventually extend to Boston in eastern Lincolnshire.
It was built largely with volunteer labour, and Sustrans asked whether
any of the volunteers had any special skills to contribute. Piers Nicholson
suggested a horizontal sundial might be constructed, and Sustrans found
the funds to commission it. The site is beside the River Witham a few
hundred metres east of the road bridge over the Witham below the cathedral.
