I-405 - NE 8th Street to SR 520 Improvement Project

Quarterly Project Report Update for Quarter Ending March 2006

Project Title & Location
 I-405/NE 8th St. to SR 520 Braided Crossing (TPA)

Project Description
This project constructs multi-level northbound braided ramps from NE 8th St. to I-405 and I-405 to SR 520. Construction also includes grade separating I-405 ramp traffic entering eastbound SR 520 from I-405 with SR 520 traffic exiting to 124th St. NE.

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

Recent Progress
Funding became available for this project in January 2006.  Preliminary engineering work over the past quarter includes project organization, scheduling, and initial investigations of environmentally sensitive areas.  Coordination with the City of Bellevue and with the SR 520 Project has continued.  In addition, detailed alignment coordination with the NE 10th St. Overcrossing project has continued and overall footprint refinement in support of a July start to the Environmental Assessment has begun.

Design Construction Impacts
The Bellevue Braids project is a complex interaction of structures.  Fully analysis of construction impacts will be determined as coordination with the SR 520 and the possible phase 2 Sound Transit projects continue.

Environmental Impacts / Compliance
A corridor wide Record of Decision for the programmatic FEIS was received in October 2002.  Project level environmental documentation will begin July 2006 with an agency and public scoping meeting.

Impacts to Traffic
Expect at least moderate impacts to traffic during construction due to the complex nature of the structures in a highly urbanized area.
