New Web site details preparations for Transit Tunnel closure

Publish Date

A new Web site provides information on how Downtown Seattle will keep moving while the Downtown Seattle Transit Tunnel (DSTT) is retrofitted for joint use by light rail and buses. The Web site was developed through a partnership of local transit agencies, the City of Seattle and Downtown Seattle business community representatives.

$16 million in downtown street improvements are on the way to help maintain transit frequency and reliability during the temporary DSTT closure, which will begin in September 2005 and will last for up to two years. During the closure, buses that currently use the DSTT will travel on downtown surface streets, with Third Avenue serving as a transit-only thoroughfare during peak commute hours.

The improvements will be carried out by Sound Transit, the City of Seattle, King County Metro Transit and Community Transit. Preparations are already underway and will continue in the coming months. Upcoming changes will include transit route and schedule modifications, plus new bus shelters, awnings and informational kiosks.

The agencies are working closely with transit passengers, the downtown business community and property owners to make sure the downtown transportation system works as efficiently as possible.

"By bringing Sound Transit's Link light rail into Downtown Seattle, we are adding another great option for commuters and visitors to downtown," said Kate Joncas, President of the Downtown Seattle Association (DSA).   "This Web site provides useful information on the tunnel project including expanded commute options for employers, visitors, businesses & building managers.  We all share a strong commitment to the continued vibrancy of Downtown Seattle."

The DSA recently launched the Urban Mobility Group (UMG) in a partnership with King County Metro and the City of Seattle to create the first one-stop shop resource for downtown employers, building managers and commuters.  UMG offers bus passes, programs and services to help employers make the most of downtown commute options. For more information click the UMG link on the new Web site. provides a single stop with information on what's happening with the tunnel closure, and links to transit schedules and service information. The site also includes links to information on the Central Link light rail project, which will dramatically increase the carrying capacity of the tunnel. The DSTT will re-open to buses by September 2007. Joint use by both buses and trains will begin when Central Link light rail opens in 2009.
