I-405 Express Toll Lanes – Reporting and Measuring Performance

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 2017, we conducted three surveys to determine how different kinds of people felt about the express toll lanes. We found that support for express toll lanes has improved, the express toll lanes have helped businesses, and most I-405 drivers think express toll lanes help the regular lanes too.


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.


Goal #3: Fund future improvements

The express toll lanes raised $74.9 million dollars in 36 months of operation. Of the total, $49.9 million has or will be used to relieve congestion and improve travel for the people who use I-405 each day.
