This structure is one of the largest canal aqueducts ever built in South Wales. Its four stone arches carry the Brecknock and Abergavenny Canal (later the Monmouthshire & Brecon Canal) across the Usk to enable boats to reach Brecon, on the north side of the river Brynich aqueduct was one of the last sections of the canal to be completed to take the canal into Brecon in 1801. The structure was designed by Thomas Dadford Junior and built by local contractors. The aqueduct is at right angles to the river, reducing its length to the minimum possible. This means that the canal, running parallel to the river, has to turn sharply on both approaches.

This lock was the first on the Monmouthshire & Brecon Canal to be restored after the canal fell into dereliction. The lock was created when the canal was built c.1800. The section of canal which crosses the river Usk on the nearby Brynich aqueduct is lower than the final stretch of water into Brecon. The bridge over the canal here is joined to the lock walls. The road continues across the river Usk on a five-arch stone bridge constructed in the late 18th century.

Moderate trail depending on the distance, plenty to explore

This is the canal tunnel that goes underneath the A40 dual carriageway. It is quite a length and the footway is narrow, so if you are on a bicycle I would suggest you take it carefully as pedestrians have right of way here.
