Light rail tunnels under I-5 in Seattle

SEATTLE (AP) -- Sound Transit officials are breathing easier since a boring machine successfully tunneled under Interstate 5 in downtown Seattle.

The Seattle Daily Journal of Commerce reports (http://bit.ly/vPEY5B ) the machine chewed its way Tuesday night just 15 feet below the lanes of traffic.

Officials said boring under the freeway was one of the riskiest parts of the $1.9 billion University Link project. Earlier this fall machines completed a tunnel under the Montlake Cut without flooding.

The three-mile light rail line between downtown Seattle and the University of Washington is expected to open in about five years.
