One week in, the new shoulder lane on Interstate 405 — the first of several planned shoulder expansions on state highways in the coming years — has reduced travel times, although officials stress that it is too early to make any official conclusions, our online news partner the Seattle Times reported Thursday.
The shoulder, which will generally be open only during the evening commute, adds a fourth lane of traffic to I-405, to go with the two existing regular traffic lanes and one express toll lane.
About 1,000 cars per hour get on I-405 at the 527 on-ramp, which previously created a forced merge into traffic and slowed down the roadway. With the shoulder lane open, cars are able to drive from the ramp straight onto the shoulder, and continue as if it’s a regular lane.
