Ramp meter set to smooth traffic flow on southbound I-5 in Lacey

Proven technology helps reduce potential for collisions

LACEY – A congestion-relieving tool is set to help southbound Interstate 5 travelers in Lacey. The Washington State Department of Transportation will soon activate a new ramp meter at the Marvin Road on-ramp to southbound I-5. The ramp meter is scheduled to turn on Monday, Aug. 1. 

Traveler benefits

Ramp meters regulate the flow of traffic entering the highway and provide consistent gaps between vehicles. The even pace makes it more predicable for travelers using I-5 and makes merging smoother for all travelers by reducing the number of vehicles merging at the same time.

The on-ramp traffic signals operate using real-time traffic conditions. WSDOT will fine tune ramp meter operations and closely monitor traffic flow. WSDOT’s goal is to balance the needs of drivers merging onto the highway with the needs of drivers already there.

The ramp meter joins a suite of other southbound I-5 meters that were previously installed between Martin Way East in Lacey and Henderson Boulevard Southeast in Olympia.

Slow down – lives are on the line. 

In 2023, speeding continued to be a top reason for work zone crashes.

Even one life lost is too many.

Fatal work zone crashes doubled in 2023 - Washington had 10 fatal work zone crashes on state roads.

It's in EVERYONE’S best interest.

95% of people hurt in work zones are drivers, their passengers or passing pedestrians, not just our road crews.
