Both tunnel entrances are Grade II listed by Historic England and are grandly built of stone, although the tunnel itself is constructed from brick. The stonework of the entrances displays a surface pattern of dense by irregular lines giving a rusticated appearance. In plan the entrances are concave with a depressed arch over the canal with an indecipherable inscription tablet above.
