SEATTLE, Wash. — The Washington Department of Transportation (WDOT) is reporting numerous highway closures and traffic disruptions after a powerful earthquake struck near Seattle yesterday.

The quake, which measured 6.8 in magnitude, struck shortly before 11 a.m. local time (2 p.m. Eastern Standard Time) and was felt as far away as Vancouver and the B.C. interior.

WDOT says the Fourth Avenue South on-ramp to eastbound I-90 in downtown Seattle will remain closed through the morning and Route 99, the Alaskan Way Viaduct, is closed from the Battery Street Tunnel to South Spokane St.

It also says Route 169 is closed at 416th Street just north of Enumclaw. On Route 202, the bridge to Fall City at milepost 2.5 is closed this morning and the road at milepost 24.5-25.5 is closed indefinitely, due to slide danger. In addition, there is a large slide blocking parts of the roadway eastbound at Fall Hill Road.

Route 302 for some distance suffered a drop and a landslide, and is closed. A detour is in place.

The Skookumchuck River Bridge on Route 507 is also closed.

Additionally, the 4th Avenue Bridge in Olympia, Wash. is closed.

No closures were reported in British Columbia.
