Railway underbridge MDL1/10, Thornhill Lane

The Railway accommodation underbridge on Thornhill Lane was built between 1845 and 1847 by Thomas Grainger for the Leeds, Dewsbury & Manchester Railway. It is constructed from Pennine Lower Coal Measures Sandstone.

The bridge features a single carriageway arch, which is flanked by deeply curving, raked wing walls that support the embankments. The semi-circular arch is made with rusticated, V-jointed voussoirs that begin from impost bands. The remaining walling consists of coursed, squared, quarry-faced masonry. At the top, the bridge has an ashlar string course and a ramped blocking course without parapets. The wing walls are also ramped, ending with simple pilaster-strips and topped with plain, squared ashlar copings. The trackside fencing and the metal gate for the archway are modern additions.
