WSDOT to install ramp meters for drivers getting on I-5 from Mercer Street
SEATTLE -- New ramp meters will be installed and tested at the Mercer Street on-ramps to north and southbound Interstate 5. Traffic engineers at WSDOT say the goal is to ease congestion for drivers on I-5 passing through the downtown Seattle area. The new signals will start pacing vehicles entering the freeway on weekends only starting March 10. After a month, crews will evaluate the metered traffic and could turn on the ramp meters for weekday traffic as early as April 10.
