A wooden drawbridge carried the road over the canal and was replaced by a fixed bridge after navigation on the canal ceased in the 1930s. Before the canal reopened to boats in 1970, a steel drawbridge with an electric operating mechanism was installed. There are four other drawbridges along the canal to the west. They are for farmers to access fields and are less elaborate than the one at Talybont. Drawbridges saved the canal company the expense of building stone bridges over the canal at these locations.

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.
