The Transportation Corridor Agencies (TCA) are two joint powers authorities formed by the California legislature in 1986 to plan, finance, construct and operate Orange County's 67-mile public toll road system. Fifty-one miles of the system are complete, including the 73, 133, 241 and 261 Toll Roads. The Toll Roads - which are owned and maintained by the state of California -- were built with virtually no taxpayer dollars.
