While they remain controversial politically, the HOT lanes on I-405 between Bellevue and Lynnwood are increasingly popular with transit users and the drivers who use the lanes. Higher than forecast driver demand has led to higher toll revenues, and those revenues are being put to work to benefit drivers in the corridor. The first improvement is a 1.8 mile shoulder lane for general purpose traffic between Canyon Park and I-5. The improvements may also benefit transit users.

As demand has grown, average peak time toll rates have crept up from $1.75 in late 2015, to $2.40 in the first quarter, to $2.72 in the second. In June, the HOT lanes served 1.2 million vehicle trips, over 800,000 of those tolled. With higher prices and HOT lane volumes, WSDOT now anticipates revenues will exceed earlier forecasts by about $20 million per biennium.
The lanes have worked well for transit too, with Metro seeing 8.2% more riders. Average travel savings are 2.1 minutes in the AM and 5.8 minutes in the PM. Community Transit’s peak ridership is up 3% with improved travel times for most routes.
Initially, express lanes were tolled at all hours. In a concession to tolling opponents in the Legislature, that was pared back earlier this year so tolls now apply only between 5am and 7pm weekdays. The lanes are open to all drivers at other times, although center HOV ramps in Bellevue and Totem Lake are HOV/transit only when tolled access is not available.
Travel times for drivers in the general purpose lanes are generally better than before, particularly southbound. In the northbound direction, traffic flows more freely through Bellevue and Kirkland. But this has exacerbated a bottleneck at SR 522 in Bothell, where five lanes (2 HOT + 3 GP) converge into three (1 HOT + 2 GP). The highway remains congested until near I-5. Nearly 1,000 vehicles an hour merge onto I-405 at Canyon Park in the PM peak, adding to delays.
