Geotechnical engineers are headed to a slide on Washington’s State Route 4. The major artery to the coast is completely blocked until further notice. Abbi Russell with Washington DOT has an alternative for drivers: you can drive through Longview cross the Lewis & Clark Bridge to Oregon, drive down to Westport and get across the Washington side there at Cathlamet. Wash-DOT is picking up the tab for drivers who want to use the Wahkiakum ferry, or drivers can continue on Highway 30 to the Astoria Megler Bridge to cross into Washington. There's no estimate on when the Highway will reopen.
