The kanji 渡 is a phono-semantic compound (形声文字). The left side is the radical 氵 (さんずい), which represents water. The right side is 度 (ド、ト) which provides the sound and the original meaning of measurement or degree, because when people pass river, they need to measure the distance. Thus, the original meaning of 渡 is crossing a river. The water radical suggests the association with rivers and crossing. Over time, it expanded to encompass crossing any barrier.
