A new book launched by the Highways Agency last week looks set to become the standard work on historic bridge conservation in the UK and overseas. 'Conservation of bridges', written by Graham Tilly of Gifford & Partners, was produced with input from bridge owners including British Waterways, local authorities, and English Heritage. It relates principally to highway structures built before 1915, of which the Agency is responsible for more than 300. Ten date from before 1700, with the oldest being the 1272 Llangau bridge on the A465 in Hereford & Worcester.
More typical of the challenge facing the modern highways engineer is this 1897 Cross Keys swing bridge on the A17 in Lincolnshire.
