Bellevue, WA - The Washington State Department of Transportation and Atkinson Construction, with its subcontractors, completed the demolition of the Wilburton Tunnel over Interstate 405 in Bellevue with just two August weekend closures of the busy freeway.

Southbound I-405 between SE 8th Street and the I-405/I-90 interchange opened to traffic at 3:20 a.m. Aug. 18 after highway crews worked around the clock over the weekend to finish demolishing the tunnel.

They used a wrecking ball, mining trucks and six hydraulic excavators with specialty attachments such as breakers and crunchers to complete the demolition of the once 360-foot-long Wilburton Tunnel one week early. Because of the team's quick work, a third scheduled weekend total closure of southbound I-405 was no longer needed.

Atkinson Construction LLC is the lead contractor on the South Bellevue Widening Project. The subcontractors include R.W. Rhine Demolition, Inc.; Novito Construction; KLB Construction; Salinas Construction; Acme Concrete; INCA; Apply-A-Line; Totem Electric; Lakeside Industries; Peterson Brothers Construction; and Jacobs Engineering.

In addition to the tunnel demolition work, crews used the total closure of southbound lanes to repair several sections of I-405 and complete preparation work to connect a new I-405 southbound bridge over I-90. This weekend's work was part of the $124-million design-build I-405 South Bellevue Widening Project, which is scheduled for completion by late 2009.
