On WSDOT’s I-405 Express, Average Lane Speed Drops Below Required Threshold.

The Herald reports that the managers of WSDOT’s I-405 Express face a new challenge: “Traffic within the lanes is now moving at 45 mph or faster just 85 percent of the time. That’s below the required 90 percent threshold, which the state had been meeting across the 17-mile tolling corridor until June.” WSDOT’s toll operations director, Patty Rubstello, told state transportation commissioners last week, “We’re looking at a whole host of things to try to address that. We want to look at any operational things that we can further refine out there to bring [the average operating speed during peak hours] back up.”
