Old Gaynes Park Footbridge stands on what was once the western perimeter of Sir James Esdaile's Gaynes Park estate in Upminster. Built circa 1765, probably by James Paine, it served as an eyecatcher — an intentional focal point facing north toward the house. Constructed of red brick with wide lime-mortar joints and traces of an original rendered finish, the single-span bridge has a round-headed arch about two metres high and three metres wide, with banded rustication, splayed voussoirs, and tapering side sections. The interior is groin-vaulted. Although most of the estate's buildings have disappeared and the grounds subdivided, the small structure survives on a public footpath between 52 and 54 The Grove. - AsNotedIn
