Loyn Bridge crosses the River Lune, carrying a minor road between the villages of Hornby and Gressingham in Lancashire, England. The present bridge replaces an older bridge, which is thought to have been constructed with timber decking between stone piers. There is evidence that the river was forded here before a bridge was built. The date of the building of the present bridge is unknown; it is considered to have been after 1591, when the previous bridge was described as being "in a dangerous condition". A date of 1684 has been suggested, but petitions regarding the bridge put before the Quarter Sessions between 1650 and 1750 make no mention of a new bridge between these dates. The bridge was paid for by the County of Lancashire, and later the responsibility for maintenance and repairs was transferred to the Lonsdale Hundred.
