The cash-strapped charity is determined to ensure the future of the region's signposts and milestones.
Some of these markers date back 250 years, with at least one - a 1755 stone direction marker, or guide stoup, high on Scammonden Moor in Kirklees - listed at Grade II*.
But English Heritage is concerned that many of these signs are in danger of falling into a state of irrecoverable disrepair.
Together with the Department of Transport, the Countryside Agency and the Campaign for the Protection of Rural England, the organisation launched the campaign yesterday.
Giles Proctor, historic buildings architect with English Heritage's Yorkshire region, said a register should be produced of all the signs.
'Traditional signs are not only attractive in their own right but have become important symbols of our identity,' he said. 'Many still survive but some are in urgent need of repair.
'We'd like to see all highways departments compile registers of historic signage and we would also encourage community groups to carry out their own audits.
'That will identify the need for repair, where possible using local craftsmanship,' Proctor added.
