Mark Yeo
River in north Somerset, England
The Mark Yeo is a short river or rhyne in north Somerset, England. It starts near Mark on the Somerset Levels and flows north for about 6 kilometres (4 mi) under the M5 motorway to join the River Axe near Loxton. It provided a link between the Axe and the River Brue, as part of a waterway called the "Pilrow Cut" probably canalised in the early 13th century. It no longer connects to the Brue, but is used for drainage purposes, which is unlikely to have been the case in the Middle Ages. Within the village of Mark, it is crossed by an iron bridge erected in 1824, which claims to be the oldest of its kind in the county.
