The Brecknock and Abergavenny Canal was promoted in 1792 to connect the upper Usk valley with the Monmouthshire Canal at Pontymoile and from there to the sea at Newport. The first section, between Gilwern and Talybont and including Llangynidr, was cut between 1797 and 1799, with the upper section between Talybont and Brecon opened in 1800, both sections engineered by Thomas Dadford. The lower section between Gilwern and Pontymoile was completed in 1812 and was engineered by William Crosley. The canal was sold to the Monmouthshire Canal Company in 1865, which was later incorporated into the Great Western Railway. The last toll was taken on the canal at Llangynidr in 1933. Restoration of the canal, renamed the Monmouthshire and Brecon Canal, began in 1964 and is ongoing.  

Aqueduct of rubble sandstone with single round arch and abutments which are splayed outwards at either end. On the towpath (N) side is plain stone parapet. On the S side an outflow from canal is inserted above the arch.  

 

An important surviving example of late C18 canal engineering.
