The viaduct is a substantial structure which carried the double-track C&WJR's Cleator Moor West to Siddick Junction via Workington Central main line over the River Keekle.

[5] It is situated between the former stations of Cleator Moor West and Keekle Colliers' Platform.

Opened in 1879, it consists of seven equal stone arches across the river.

Goods and mineral trains, with very occasional passenger excursions and diversions continued to use the line until it closed completely on 16 September 1963.

The structure was offered for sale for £1 in 1992, but there was no initial response, as any purchaser would have to maintain and repair it, rather than demolish it and recover the stone.
