Metro has been studying various options to add a rail line connecting riders from Van Nuys to the Expo Line just north of the 10 Freeway - making for a quick 10-minute trip. A second phase could extend to Los Angeles International Airport.
But the price tag would cost as much as $13.8 billion - significantly higher than what was first estimated by Metro.
More than $5 billion of the project is funded through Measure M, which was approved by voters. However, the remaining funding is in question.
L.A. Metro spokesman Brian Haas said the agency is looking at four options: three involve trains and subways, and the fourth could look like the Disneyland monorail.
Regardless of how the transit line is built, Metro says it's studies show it will be used to the tune of 120,000 boardings a day by its estimates.
Metro estimates more than 400,000 drivers travel through the Sepulveda Pass each day.
The Sepulveda Line is expected to open in 2033, but it could open as soon as 2028 - just in time for the Olympics.
