A proposal to add high-occupancy toll lanes to the San Diego Freeway in Orange County, including a stretch of the 405 through Costa Mesa, took a step forward this week when the O.C. Transportation Authority’s board approved further environmental and engineering study of the project.
A report presented to the board found that the idea is financially viable and would help pay for the cost of the freeway expansion, which could cost as much as $2.2 billion. The board on Monday decided to explore the option more fully.
The proposal to add a general-purpose lane and a high-occupancy toll lane in each direction on the 405 between the 73 and the 605 freeways is one of several options being explored. There is already one carpool lane in each direction that would be converted into a high-occupancy toll lane, so it would create a total of two express high-occupancy toll lanes in each direction.
