We have three goals for the I-405 express toll lanes which determine how and what we report on: to provide a choice for drivers, to provide a faster and more predictable trip, and to fund future improvements.

Goal #1: Provide a choice for drivers

In the summer of 2018, we conducted a survey to determine how  people felt about the express toll lanes. We found that support for express toll lanes has improved, and most I-405 drivers think express toll lanes help them save time.

Goal #2: Provide a faster and more predictable trip

The express toll lanes were designed to provide drivers with the option of a faster, more predictable trip. There are a variety of performance measures to determine whether the express toll lanes are providing this valuable choice to drivers, including speeds, travel times and reliability.

• Learn how reliably the express toll lanes flow at 45 mph or faster (pdf 1.6 mb).
• See how the express toll lanes are improving performance in the regular lanes (pdf 1.6 mb).
• Find out how much time drivers save (pdf 1.6 mb) on average when they use the express toll lanes.

Goal #3: Fund future improvements

The express toll lanes raised $90.2 million in 42 months of operation. Of the total, $60.3 million has or will be used to relieve congestion and improve travel for the people who use I-405 each day.

• See where your money goes when you pay a toll on I-405.
• During the last quarter, the average toll rate during peak periods was $4.23; learn how much time people typically save for each dollar spent.
