I-405 - SR 520 to I-5 Widening Project

Quarterly Project Report Update for Quarter Ending December 2007

Project Title & Location
I-405/SR 520 to I-5 Widening (Nickel and TPA)
WINs: U40561B, U40501K, U40502K
PINs: 840561A, 840561D, 840566E, 840567B, 840576A

Project Description
Combines the Kirkland Nickel Stage 2 with TPA projects: Stage 2 adds 1 northbound lane from NE 70th to 85th, and 1 additional southbound lane from SR 522 to NE 124th and from 85th to the SR 520 area. TPA projects add a northbound lane from NE 124th to SR 522 and from NE 195th St. to SR 527. Also constructs new NE 132nd St. NB and SB I-405 bridges.

Contractor/Consultant
HNTB Corporation is the lead consultant of the General Engineering Consultant Team.

Recent Progress
As requested by the Legislature in 2005, this project continues to evaluate Express Toll lanes, which are not funded currently. Environmental documentation is being prepared based on two alternatives. The first alternative is a two-lane Express Toll lane system between SR 520 and SR 522, and a one-lane system between SR 522 and I-5. This alternative also includes conversion of the High Occupancy Vehicle lanes to Express Toll lanes from SR 522 to I-5. The second alternative would operate the additional lane as a general-purpose lane. Note that reported project costs and milestones shown below are based on the Legislature’s Final 2007 Transportation Supplemental Budget (07LegFin).

Design Construction Impacts
This project includes replacing the northbound and southbound bridges on I-405 at NE 132nd Street.

Environmental Impacts / Compliance
A corridor-wide Record of Decision for the programmatic Final Environmental Impact Statement was received in October 2002. The environmental process for this project is ongoing.

Impacts to Traffic
Moderate construction impacts are expected.

Project Milestones Scheduled Attained Milestone Outlook
Preliminary Engineering Start (Nickel funding)(TPA funding) July 2003 Jan. 2006 July 2003 Jan. 2006 The Nickel portion of the project engineering began in advance of the TPA projects, and is now being coordinated with the TPA dates. TPA Preliminary Engineering work began in January 2006.
