Pentrefelin Bridge, Llangollen Canal Bridge No 48

Rubble single span elliptical arched bridge with ashlar dressings, characteristic of Telford's design. Voussoirs and keystone with stringcourse above parapets follow the roadway in sloping gently downwards to the S; and curving back at either end with ramps down to the towpath at the S, terminating in slight pilasters with pyramidal caps (broken to E). The abutments are slightly battered at the feet. On the S side the road running E has a mudstone retaining wall, sloping down to approximately 2m above the towpath; this has later been heightened and extended to the W to terminate in a coped rectangular pier. An oval cast iron plate on the E side bears the number 48.
