August weekend construction to keep traffic slow in Seattle

| 8/8/2008

Multiple Seattle-area construction projects scheduled during weekends in August could lead to traffic back-ups as long as 13 miles, some media outlets are reporting.

The Washington Department of Transportation announced recently that it will close southbound lanes of Interstate 405 near Interstate 90 from 11 p.m. Fridays to 5 a.m. Mondays on the weekends of Aug. 8-11, Aug. 15-18 and Aug. 22-25.

Also, the onramp from Renton to the southbound I-405 lanes will be closed from 10 p.m. Aug. 8 through noon on Aug. 11 as part of the state’s $1.4 billion overhaul to I-405.

Drivers may use Interstate 5 and Washington Route 520 as detours during the construction, but state officials said normal traffic using detours could lead to backups as long as 13 miles, according to the Seattle Post-Intelligencer.

“Even with reduced travel, drivers should give themselves two extra hours to get around the region,” Stacy Trussler, Washington’s deputy I-405 project director, told the newspaper.

The state DOT has posted electronic messages on highway signs to warn drivers of the shutdowns.
