Description

The driveway bridge at Voelas is a Grade II listed structure made of rubble stonework. It features a tall stilted arch that spans the stream between high banks, constructed with radial voussoirs that rise to a central keystone, all outlined by a regulating course. To the west, there is a sharply raking buttress and another flood arch of similar size that rises from the top of the bank. The bridge includes a horizontal string course and a flush parapet that is coped with stone. The driveway itself is level.
