Olympia— The Washington State Department of Transportation is starting its 2009 construction season in February, a month or more earlier than normal, because of the volume and complexity of work to be completed in the Central Puget Sound region this year.
According to WSDOT, the work will affect every major road in the greater Seattle area.
The biggest projects will replace broken concrete panels on I-5 between the Boeing Access Road and the King/Snohomish county line; repair uneven pavement on I-5 between the Ship Canal Bridge and 145th Street; and replace expansion joints on the I-90 floating bridge.
Other projects that will hit commuters include:
- Repaving SR 520 in Redmond;
- Rehabilitating the Battery Street Tunnel;
- Building a new connection between I-90 and the south end of the Viaduct over Royal Brougham;
- Widening I-405 in Renton and Bellevue;
- Applying a test section of quieter pavement in South Bellevue on I-405;
- Closing the Hood Canal Bridge in May and June;
- Multiple paving projects on I-5 in Snohomish County.
WSDOT says it must repair the failing roads before beginning next year's mega-projects: the Seattle Viaduct and the replacement of the SR 520 floating bridge. Existing roads must be able to handle thousands of extra vehicles every day during these construction projects.
