Description
The Saltford Tunnel East Portal is a Grade II listed structure made from ashlar Bath stone, featuring a depressed, four-centred arch that spans 30 feet (9 meters). The arch is constructed with ashlar voussoirs and has a recessed roll followed by a hollow moulding, although no stops are visible, which may be hidden beneath ballast as indicated in the contract drawings. The arch is framed by a large square hoodmould with stops, which highlights chamfered spandrel panels.
This portal is set within a retaining wall made of coursed Pennant stone that extends above and to the sides, topped with a plain coping course that rises gently to a peak at the center. On the south (Down) side, there is a low coursed rubble retaining wall that features a segmental-arched niche with a basin, possibly serving as an outlet for a natural spring, which is not depicted in the existing contract drawings.
The tunnel itself is not very deep, and the surrounding area is characterized by the buildings and gardens of the village of Saltford, which are situated on the low hill above the portal.
