SEATTLE (AP) — Another blast of snow halted travel on a large portion of the main east-west highway across Washington state Thursday and also snarled traffic in the Seattle and Portland, Oregon, metro areas.

Authorities closed about 80 miles (129 kilometers) of Interstate 90 over the Cascade Mountains “due to near zero visibility and adverse road conditions.” There was no immediate estimate as to when the interstate would reopen.
