The famous viaduct is often mentioned by historians and railway enthusiasts. It is a listed building grade II* and listing details are here:button_blue_play

The transport Heritage site has some good information: button_blue_play; and Wikipedia (see link above) has some limited information.

The viaduct was completed in 1863 by the Central Wales Railway, and the line was opened in 1864.  It is 190 yards long and consists of 13 arches and is 75 feet high. Its major features are the castellated towers at either end and the embellished parapets. Then the line southwards rises at 1 in 60 (the steepest part of the line) to the highest point of the line at 320m (980ft) as the line leaves the Llangunllo tunnel.

HOWLTA have produced a small pamphlet to celebrate the 150th anniversary of its opening: see here and here Viaduct history
