Project Title & Location
I-405/SR 520 to SR 522 in Kirkland
|
Project Description
This project combines Kirkland Nickel Stage 2 and Transportation Partnership Account (TPA) components to add a continuous northbound and southbound lane between SR 520 and SR 522. Stage 2 adds one northbound lane from NE 70th Street to NE 85th Street, and one southbound lane from SR 522 to NE 124th Street and from NE 85th Street to the SR 520 area. TPA projects add a northbound lane from NE 124th Street to SR 522 and from NE 195th Street to SR 527.

Recent Progress
The I-405 Kirkland Nickel project is now one year ahead of schedule. This congestion relief project addresses the "Kirkland Crawl". The request for proposals for design-build was issued in July and bids were received in August. After evaluation, this design-build contract was awarded on September 26, 2005. Project mobilization began almost immediately, with the state and contractor construction teams co-located in the project area. With co-location, agreements and other mobilization efforts complete, Stage 1 remains ahead of the Legislative approved schedule. Simultaneously, Stage 2 preliminary engineering remains on schedule. The close coordination efforts of the Multi-Agency Permitting Team and local jurisdictions allowed all Stage 1 permit approvals to be received in time to meet this schedule and results in the project opening to traffic in December 2007, one year early.

Design Construction Impacts
This is a widening project that will be constructed in two stages. Stage 1 provides one additional lane in both the northbound and southbound directions from NE 85th to NE 124th. Stage 2 provides one additional northbound lane from NE 70th to NE 85th and one additional southbound lane from SR 522 to NE 124th and from NE 85th to SR 520.

Environmental Impacts / Compliance
The Services concurred with the Biological Assessment at the end of October 2004. The Environmental Assessment was signed February 23, 2005 with the public comment period ending on March 23, 2005. Finding of No Significant Impacts was obtained April 14, ahead of schedule. The final permits were received in early July 2005.

Impacts to Traffic
Pavement is widened to the outside of the existing roadways so impacts to the traveling public is expected to be minimized during construction. Close coordination continues with the adjacent Sound Transit direct access project: I 405 Totem Lake Freeway Station/ NE 128th.
