Seattle’s Sound Transit had a challenging problem: how to get a new light-rail line on and off a nearly 1-mile-long Interstate 90 floating bridge while protecting the rails from the constant movement of the water.
Sound Transit's plans for expanding light rail in the south Puget Sound in Tacoma became more public recently at an open house at Evergreen State College.
Six tunnel segments on a single light rail extension project offered plenty of opportunity for Sound Transit to run amiss of target dates, costs and plans.
Confronting a spaghetti bowl of roads in and out of SeaTac International Airport, south of Seattle, owner Sound Transit opted for its first-ever turnkey design-build contract to better integrate civil, structural, station and system components of a new light-rail system extension that will serve the airport.
When he was Federal Transit Administration chief, Peter M. Rogoff in 2009 OK’d $813 million in federal grants to Seattle-area rail agency Sound Transit to boost construction of a regional light-rail line.
