I-405 - NE 8th Street to SR 520 Improvement Project
*Quarterly Project Report Update for Quarter Ending December 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. This complex series of collector-distributor ramps will eliminate the I-405 to SR 520 weaving, while minimizing congestion by shifting I-405 access to SR 520 from NE 8th St. to NE 4th St. and NE 10th St. The combined effect of separating traffic movements and increasing distance between access points will improve safety and traffic operations. A design refinement meeting held in August 2006 verified the design concepts and made recommendations for design improvements. Appraisals for right-of-way acquisitions along I-405 commenced in November 2006. In addition, the project notified affected utilities of project plans in November. Also, note that reported project costs are based on the Legislature's Final 2006 Transportation Supplemental Budget.
Design Construction Impacts The Bellevue Braids project is a complex interaction of structures. Full analysis of construction impacts will be determined as coordination continues with Overlake Hospital Medical Center, SR 520 Bridge replacement and the possible Sound Transit Phase 2 projects.
Environmental Impacts / Compliance A corridor wide Record of Decision for the programmatic Final Environmental Impact Statement (FEIS) was received in October 2002. Project-level environmental documentation began in July 2006. The overall footprint refinement freeze was completed in December 2006 to support the Environmental Assessment process. Public and agency scoping meetings were held in September 2006, while Environmental Discipline Reports commenced in October 2006.	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.
