The California Department of Transportation (Caltrans) is one of a growing number of agencies implementing innovative solutions to meet the modern challenges of traffic and construction management. In Redding, Calif., two small pieces of guardrail were giving the agency and the community a big headache. The guardrail was installed on each side of a tight cloverleaf ramp system that connects I-5, a major statewide artery, with S.R. 44. The guardrail in this area was hit numerous times each year.
