    405 Freeway Expansion Project Overview

    http://www.octa.net/405improvement
     
    OCTA in cooperation with The California Department of Transportation (Caltrans) is widening the San Diego Freeway (I-405) between State Route 73 (SR-73) and Interstate 605 (I-605).The project will improve 16 miles of I-405 between the SR-73 freeway in Costa Mesa and I-605 near the L.A. County line. The project includes adding one regular lane in each direction from Euclid Street to I-605 and making improvements to freeway entrances, exits and bridges. It also will construct the 405 Express Lanes, two lanes in each direction from SR-73 to I-605. The new express lanes – incorporating the existing carpool lanes and connectors that opened in 2014 – will give solo drivers the choice to speed up their commute for a toll, and carpoolers may ride in the lanes for free.

    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.
