Weldon Canyon

The original road through the canyon was 20 feet wide and made of concrete. The canyon is named after Arthur Weldon, who helped build the Southern Pacific Railroad’s nearby San Fernando Tunnel.

Weldon Canyon refers to a canyon west of Vacaville. This area is more commonly known today as Mix Canyon, and Mix Canyon Road runs through it. The canyon is mentioned in the diaries of Willis Linn Jepson.
