After drivers endure gridlocked crossings on Seattle’s Mercer Street, they’ll see one more set of traffic lights to pass before finally getting the opportunity to merge into Interstate 5.

Ramp-metering signals will be installed at the northbound and southbound freeway entrances, to operate weekends only starting March 10 — and then every day beginning April 10.

The $250,000 project is meant to even the flow at which cars enter the crowded freeway, so merging becomes easier, and people driving on I-5 slam their brakes less often.
