Solo drivers buy into a carpool lane at $0.10 a mile, capped at $3.10. The federal evaluation found the revenue arrived and the driving did not fall: vehicle-miles travelled rose 30.5% on the I-10.

Metro converted 25 miles of carpool lanes on the I-110 (November 2012) and I-10 (February 2013) into lanes solo drivers may buy into. Unlike a cordon charge it prices one lane, not an area, and the rate is recalculated from live detector data — $0.10 per mile off-peak to a $3.10 cap. A federal demonstration; SB 1298 made it permanent in September 2014.

Live 📅 since 2012

📊 Impact

The US DOT national evaluation found gross tolls of $18,704,961 on the I-110 and $8,918,985 on the I-10 in the first 16 months, but also that vehicle-miles travelled rose 30.5% on the I-10 and 6.6% on the I-110 while fuel economy fell, at an estimated $104,566,154 in extra fuel. Metro counts more than 340 million trips and over $100 million reinvested in the two corridors by 2022, including 42 net-toll-revenue grants worth $47.6 million.

🎓 Lesson

Pricing one lane is politically easier than pricing a cordon, and it can be locked in by statute — but it sells a faster trip rather than less driving: the federal evaluation found traffic and fuel use rose on both corridors.

↗ Metro ExpressLanes — Frequently Asked Questions (operator)How the price is set: 'we gather data in real-time from hundreds of detectors installed throughout the ExpressLanes and use that information to calculate what the toll rates should be at any given moment.' Also the occupancy rules (I-110 free for 2+ at all hours; I-10 free for 3+ at all hours, 2+ only off-peak), the FasTrak Flex switchable transponder still required to claim the carpool exemption, and Pay-As-You-Go for drivers without one (toll plus a $9 processing fee). Metro states elsewhere on the same site that rates are set to hold at least 45 mph as often as possible; that page would not render for us, so the target is noted here rather than claimed in the entry.
↗ Metro ExpressLanes — toll rate increase, 6 October 2025 (operator)Current rate band: maximum raised 'from $3.00 per mile to $3.10 per mile'; minimums of $0.35 per mile peak and $0.10 per mile off-peak unchanged. Peak is 5am-9am and 4pm-7pm on weekdays; the lanes run 'in the center lanes of I-10 and I-110, seven days per week, 24 hours per day.'

A companion finding from the same evaluation states net emissions rose 26 to 82 percent on the I-10 and 6 to 21 percent on the I-110; that page returned 403 to us and the figure is therefore kept out of the entry's impact.

What the price is actually attached to

Every scheme here charges for driving, and each attaches the charge to a different thing: a road segment, an area, a single lane, or a digit on the number plate. What the price is bolted to decides what it can and cannot do.
