At a Calaveras County Board of Supervisors meeting on Dec. 8, the board held a public hearing and unanimously approved a resolution of necessity to acquire property interests through eminent domain in order to carry out the State Route 4 Wagon Trail Project. The Wagon Trail project, which has formally been in the works since 2001, aims to realign and improve a roughly six-mile stretch of Highway 4 between Copperopolis and Angels Camp. The road has changed little from its original course in the 19th century, when it carried wagons to and from Calaveras County long before the advent of the automobile. âThe narrow width and non-engineered geometry of the roadway, combined with large traffic volumes (5,000 vehicles per day), reduce roadway operating speeds to approximately 25 to 35 mph and precipitate a higher than average accident rate throughout this segment (66 collisions in the most recent three-year period),â the meeting packet reads. âAs development continues within the county, the projected traffic growth is expected to result in a Level of Service E (unstable flow, operating at capacity) traffic operations by 2025.â
