Saltford Tunnel West Portal (MLN111164)

The Saltford Tunnel West Portal is a Grade II listed structure made of ashlar Bath stone for the portal and copings, with squared and coursed Pennant stone used for the retaining walls and tunnel lining, along with small patches of engineering brick.

The portal features a depressed, four-centred arch that spans 30 feet (9 meters). This arch is constructed from ashlar voussoirs and includes a recessed roll followed by a hollow moulding that extends to the ground without visible stops. The arch is framed by a large square hoodmould with stops, which highlights the chamfered spandrel panels. The ashlar portal is integrated into a coursed Pennant stone retaining wall that rises above and to the sides, topped with a plain coping course that gently peaks at the center.

The tunnel itself is not very deep, and the village of Saltford, with its buildings and gardens, is situated on the low hill above the portal.
