FOR IMMEDIATE RELEASE: Thursday, October 11, 2007

Two lanes on northbound I-405 to close this weekend

Crews working for the state Department of Transportation (WSDOT) will close two northbound lanes of Interstate 405 near Coal Creek Parkway in south Bellevue this weekend for pile driving work. Motorists who don't choose alternate routes or carpool can expect long backups on the highway between Renton and I-90.

From 5 a.m. to 10:30 a.m., on Saturday and Sunday, the two lanes will be closed between 112th Avenue Southeast and Coal Creek Parkway. At 10:30, one of the lanes will open. The second will open at 12:30 p.m. each day.

To help prevent congestion, WSDOT officials urge travelers to take one or more of the following actions:

  • Plan before you go by checking the WSDOT Seattle Area Traffic web page or calling 5-1-1.
  • Take alternate routes, including I-5.
  • Allow extra time for travel or reschedule trips.
  • Carpool or ride the bus.

The work is part of the I-405 South Bellevue Widening Project, which includes four miles of roadway from 112th Avenue Southeast to Southeast 8th Street. The work is designed help relieve congestion on one of the worst I-405 bottlenecks by adding lanes and improving merging conditions on the drive into and out of downtown Bellevue. Construction began July 9 and will be complete by the end of 2009.

“To prevent severe congestion on northbound I-405, we need drivers to delay trips, or take alternate routes if possible,” said Seema Javeri, WSDOT project engineer. “Those who must drive through the area need to pay extra attention to safety and slow down in the work zone.”

“While the two lanes are closed, crews will drive steel piles in the ground next to the highway on the east side of I-405 at Coal Creek Parkway to begin widening the bridge,” said Javeri. “We need to close the lanes to keep drivers safe. Although most construction work is done at night when traffic volumes are low, crews need to work in the daylight to clearly see the pile driving operation and ensure that the piles are straight.”

WSDOT will provide information to drivers on variable message signs, highway advisory radio and via the toll-free, traveler information phone line accessed by dialing 5-1-1.
