Cadw's description

Situated some 500m S of centre of Bethesda, S of R.C. church.

Early C19 road bridge carrying Thomas Telford's Holyhead road over the River Caseg. Marked on 1889 O.S. as 'Pont y Gaseg or Pont Aberogwen'.

Rubble stone single arched road bridge. Broad elliptical arch with squared stone voussoirs, string course above, and two raking buttresses each side. String course broken forward over outer buttresses. Rubble stone W parapet with slate edge-on coping. Bridge has been widened on E side with flat concrete span, but not altering bridge structure except for loss of E parapet.

Handsome single span road bridge, possibly designed by Thomas Telford as part of the Holyhead road.
