The aqueduct consists of ten arches, each with a span of 40 feet (12 m). The water level is 65 feet (20 m) above the ground and 70 feet (21 m) above the River Ceiriog.The stone work is yellow sandstone.William Hazledine provided the ironwork for the aqueduct.Originally built with iron plates only at the base of the trough, iron side plates were added to the aqueduct in 1870 to alleviate leakage
The Chirk Tunnel starts at the north end of the Chirk Aqueduct, allowing the canal to continue on towards Llangollen. Chirk Railway Viaduct was built later alongside the aqueduct. It is slightly higher than the aqueduct.
The aqueduct was designed by civil engineer Thomas Telford for the Ellesmere Canal. The resident engineer was M. Davidson who also acted as resident engineer on a number of Telford's other works. The foundation stone was laid on 17 June 1796 and it was completed in 1801.It has a cast iron trough within which the water is contained. The masonry walls hide the cast iron interior. The aqueduct followed Telford's innovative Longdon-on-Tern Aqueduct on the Shrewsbury Canal, and was a forerunner of the Pontcysyllte Aqueduct, also on the Llangollen Canal. The aqueduct was briefly the tallest navigable one ever built, and it now is Grade II* listed in both England and Wales. It forms part of the Pontcysyllte Aqueduct World Heritage Site.
