Towpath
(重定向自Tow path)
A towpath is a road or trail on the bank of a river, canal, or other inland waterway. The purpose of a towpath is to allow a land vehicle, beasts of burden, or a team of human pullers to tow a boat, often a barge. This mode of transport was common where sailing was impractical due to tunnels and bridges, unfavourable winds, or the narrowness of the channel.
