Where does the San Diego River walking trail in Mission Valley begin and end? (in San Diego, CA)?

If anyone has a link to a trail map, that would be great.

The original trail goes from the mountains to Old Town but it’s been cut up due to the roads. There are maps that the library may have on how to do the trail, but it’s like trying to follow Route 66, almost impossible to do from beginning to end. There has been a push to eventually have a continuous trail. The ones in Mission Valley usually have homeless out and about.
