Santa Clarita has added new red light cameras at three intersections. The new cameras went into effect Aug. 1 at McBean Parkway and Valencia Boulevard; Bouquet Canyon and Newhall Ranch roads; and Sierra Highway and Soledad Canyon Road. The cameras are posted high above the intersections and relay images to the police department. For the month of August, violators caught by the camera will be issued a warning in the mail. Starting Aug. 31, citations will be mailed. Cameras have been in place at five Santa Clarita intersections since 2002 and have resulted in an 80 percent reduction in collisions during the first year in operation, according to the city traffic division
