SR 526 Corridor Improvements Online Open House



Continued economic and population growth in and around Everett causes regular congestion on State Route 526. Our pre-COVID-19 traffic counts estimated 74,000 vehicles each day. We’ve spent the last few years studying different options to help relieve SR 526 congestion and reduce cut-through traffic in nearby communities. Through this open house we are excited to share the preferred alternative package of improvements with you:

  • A new eastbound lane between Seaway Boulevard and I-5
  • Widened Seaway Boulevard eastbound on-ramp
  • Better signal operations at the SR 526/SR 527 intersection
  • Improvements at the eastbound SR 526 ramp to northbound I-5
