As if the Alaskan Way Viaduct closure Saturday morning weren’t enough, the viaduct will be closed again this weekend — Saturday and Sunday — for semiannual inspections. Both decks will be closed both days to all vehicle traffic from 6 a.m. to 6 p.m. between South Spokane Street and the Battery Street Tunnel at the north end of downtown Seattle.

The closure is expected to cause more congestion not just on Highway 99 but also on all major north-south routes through town, including Interstate 5.

Drivers are advised to allow extra time for trips. Traffic conditions can be checked online at Drivers can also get traffic updates by calling the state driver-information line — 511.

Getting around

At Seattle-Tacoma International Airport, the two “return-to-terminal” ramps are being permanently closed today, and those ramps will be torn down in the next few weeks. The ramps are being removed as part of extending light rail to the airport and other major airport roadway improvements, including a new return-to-terminal loop able to handle more traffic.

The return-to-terminal ramps have been used mostly by drivers who circle the airport while waiting to pick up arriving passengers. The ramps also were used to reach the airport’s terminal curbside from the south entrance off International Boulevard.

Here’s the new traffic pattern: From the south airport entrance at South 182nd Street, drivers will be able to reach the airport garage, but they will have to use a detour to reach the departure and arrival areas, the ground-transportation center and rental-car-return areas. Traffic entering from South 182nd Street will have to detour to a return-to-terminal route, reachable by South 170th Street and Air Cargo Road.

Airport officials say that the best way to pick up arriving travelers is to park in the airport garage and walk to meet them in the baggage-claim area.

The detours may mean some delays for passengers.

Light-rail service to the airport is scheduled to start in December 2009.

Crime-prevention workshop

The National Crime Prevention Council will hold a crime-prevention training program, focusing on gang prevention in local refugee communities, Wednesday at the Doubletree Hotel near Seattle-Tacoma International Airport, 18740 International Blvd.

Issues will include preventing young people from joining gangs. Free training sessions are scheduled, but attendance is limited.
