This formed part of Thomas Telford's improvement of the Birmingham Canal and was built around 1828. The work incorporated the 3.6 mile long Smethwick Cutting, at the time one of the largest earthworks to have been carried out.

The Engine Arm intersected the line of the new cut, but was needed for two main reasons – firstly to maintain a supply of coal to the Smethwick Pumping Engine, and secondly to maintain the water supply from Rotton Park Reservoir into the old summit level.

The aqueduct consists of a cast iron trough, 8 feet wide, supported on a cast iron arch of 52 feet span consisting of 5 ribs, three of which support the trough with the outer ones supporting the towpaths and bracing to the sides of the trough. The towpath support consists of an arcade of Gothic arches with quatrefoil spandrels.

As with most of the bridges erected as part of the Telford rebuilding, the ironwork was cast at the Horseley Iron Works at Tipton.

The aqueduct is Listed Grade II* and is also designated as a Scheduled Monument. The Listing includes the brick arch towpath bridge at the junction.
