The general purpose lane portion of the project is a Measure M (Orange County’s half-cent transportation sales tax) project and will be funded by a combination of local, state and federal funds, with the express lanes portion of the project financed and primarily paid for by those who choose to pay a toll and use the 405 Express Lanes.
Because of the high demand for the I-405 and the need to stay within the existing right of way, the project cannot provide enough additional lanes to eliminate congestion. The 405 Express Lanes, however, will provide a fast, stress-free travel option. Because the amount of traffic in the 405 Express lanes will be optimized by raising and lowering tolls in response to traffic demand, the 405 Express Lanes will be more predictable and move more vehicles per lane during peak periods than the regular, general purpose lanes. Solo drivers in the 405 Express Lanes will pay the full toll and carpools are anticipated to be offered discounts or free travel. The toll policy has not been finalized yet but it will be designed to provide customers with a safe, reliable, congestion-free commute. The 405 Express lanes will offer people a choice to travel faster when they absolutely need to.
In 2040, it’s expected to take 29 minutes to travel during rush hour from SR-73 to I-605 in the general purpose lanes after improvements to the I-405 are complete. That commute can be reduced to 13 minutes if a driver chooses to take the 405 Express Lanes.
