History

Collinsville was part of the Montezuma Township when purchased by C. J. Collins around 1859. S. C. Bradshaw later purchased the land and renamed it Newport in 1867. He tried to sell pieces of the land to people on the East Coast telling them that it was going to be a big railroad town. The land was later sold to E. I. Upham who returned the name Collinsville back to the town in 1872. At one point, one of the passenger railroad lines between Sacramento and San Francisco passed through Collinsville (before the bridges were built). The train would unbuckle at Collinsville, and be pulled across the Delta by barge (requiring several trips), and then be rebuckled together on the other side at the foot of Railroad Avenue in Pittsburg, and resume its trip to San Francisco. On July 4, 2014, nearly half the town was lost due to a fire.
