LOS ANGELES -- Los Angeles County transportation officials will study whether drivers who are alone in their cars and are willing to pay a toll should have access to the 405 Freeway's carpool lane through the Sepulveda Pass.
The Metropolitan Transportation Authority on Thursday hired the engineering firm WSP USA Inc. to study how to convert the 405's carpool lane into a toll lane that would grant access to single-occupancy drivers, for a fee.
The toll lanes would run between the 101 Freeway in the San Fernando Valley and the 10 Freeway in West L.A.
The three-year, $27.5 million study will examine whether the toll route should have one or two lanes in each direction, and what Metro should charge solo-occupancy drivers who want to use them.
If Metro's directors approve the toll lanes, they would open to drivers in the fall of 2027, just before Los Angeles hosts the 2028 Summer Olympics, officials said.
The toll lanes are being developed in concert with a rail line that will connect the Valley to the Westside. The project, either a subway or a monorail, has an estimated price tag of $9.4 billion to $13.8 billion and calls for a tunnel as long as 13 miles through the Santa Monica Mountains.
The line is slated to open between 2033 and 2035. Los Angeles Mayor Eric Garcetti and other elected officials on Metro's board have pushed to complete the mega-project in time for the Olympics.
The operation of the 405 toll lanes would be modeled after the ExpressLanes on the 110 Freeway between Exposition Park and the South Bay and the 10 Freeway between downtown and El Monte.
Drivers who are alone in the car and enter the toll lanes are charged a per-mile rate that starts at 25 cents and rises as high as $2.10 as congestion in the paid lanes grows worse. The maximum total toll is $23.10 on the 110 and $29.40 on the 10.
Metro is also soliciting a study of how much drivers would be willing to pay, which will help set the tolls for the 405 corridor, said Philbert Wong, a senior manager of transportation planning at Metro.
