By 5 a.m. Saturday morning, April 24, WSDOT  will open a new westbound off-ramp from I-90 and I-5 that connects to the existing S. Atlantic Street/Edgar Martinez Drive S. overpass. The new off-ramp is a key component of the SR 519 Project as it will provide a faster, more reliable route for trucks to and from the Port and improve access to the waterfront and events at Seattle’s stadiums.
