Transportation Corridor Agencies (TCA) are two joint powers authorities formed by the California State Legislature in 1986 to plan, finance, construct, and operate Orange County's toll roads.
Some California lawmakers and toll road advocates favor using similar local agencies to build and maintain tollways, especially after the controversy of authorizing a private company to initially run the 91 Express Lanes.
[7] By March 2020, Transportation Corridor Agencies officially abandoned plans to extend State Route 241 through San Clemente.
[9] Toll facilities owned and operated by the Orange County Transportation Authority (OCTA) fall outside TCA's jurisdiction, including the 91 Express Lanes between SR 55 in Anaheim to the Riverside County line, and the 405 Express Lanes between SR 73 in Costa Mesa and the I-605/SR 22 interchange in Seal Beach.
[10] In 2020, the Orange County Grand Jury released a report that stated that the Transportation Corridor Agencies has completely fulfilled its original mandate, while criticizing them for trying to involve itself in future toll planning by claiming that, "much of the planning is being performed by consultants and TCA staff, who have a financial interest in seeing the TCA continue beyond its original mandate, and out of view of many of the TCA board members and the public thus creating a conflict of interest issue”.
