East Bridge lies on the eastern edge of the small village of Mid Calder, now essentially a suburb of Livingston New Town. It carries the B7015 across the Murieston Water and dates back to 1794. It is also sometimes known as the Linhouse Bridge - the Linhouse Water flows into the Murieston Water just above the bridge, and the short channel between the confluence and the River Almond seems to go by either name. The structure consists of two tall stone arches spanning the river, with a substantial triangular cutwater protecting the central pier. A stone occulus passes through the spandrel above the pier, ringed with cut stones similar to the arch rings, while the body of the bridge is rubble stone. a toothed cornice line crosses the bridge at road level, a little above the crown of the arches, above which the parapets are built of coursed rubble stone with a slender pilaster over the central pier and occulus. Various metal bars and ties have been inserted through the structure in the past in order to strengthen it.
The bridge carries a narrow S2 roadway, with a narrow pavement on the western side only. The parapets bulge out in quarter-octagonal turret like shapes at each corner over the abutments, producing an impressive view from the river. The parapets have been topped with short metal railings where the pavements are, as they were presumably deemed too low otherwise in the past.
