Recent Progress
Record of survey, wetland/sensitive area identification and discipline reports have been completed. A second project scoping meeting with the local, state, and federal regulatory agencies to present the alternatives analysis for siting the new Snohomish River bridge was held July 20, 2006. The final Archy./Historical/Cultural resource report has been completed and the report has been forwarded to the Tribes for review. The core team narrowed down the alignment and bridge options and has met with Management to determine final option for the river crossing. The selected bridge option may have impact on the project budget. A cost risk assessment workshop was completed in June 2006 with the results scheduled to be ready by the end of July 2006.

Environmental Impacts / Compliance
Mitigation efforts will include avoidance measures and adherence to state and federal permit requirements.
This project will construct storm water treatment facilities for both water quality and quantity. Use of temporary erosion control measures during construction will minimize impacts.

Impacts to Traffic
Construction will start in 2009, traffic will experience narrower lanes & shoulders, slower speeds, and some advanced publicized nighttime and weekend closures may occur (detours will be provided.) All 4 lanes should be open to traffic by summer 2012.
