Project Title & Location
SR 167 – Southbound 8th St. E Vic. to S 277th St. Vic. HOV/HOT Lane
Auburn to Pacific
|
Project Description
This project will construct a south-bound HOT lane from where it ends currently at 37th St. NW to the vicinity of 3rd Ave. SW. A drop lane will be constructed from the vicinity of 3rd Ave. SW to the 8th St. E interchange. Ramp meters will be installed at the following ramps: 15th St. SW (SB), Ellingson Rd. (SB), and 8th St. E (SB). New interim signals will be installed at the 8th St. E/SR 167 SB ramps and the Ellingson Rd./SR 167 SB ramps intersections.

Recent Progress
Scoped and negotiated final environmental work with GEC consultant. Completed wetland mapping fieldwork. Conducting stream surveys to assess impact and document habitat for resource agencies and the tribes. Field Investigation of all fish bearing culverts. Coordination with the City of Auburn, the Port of Seattle and the US Army Corps to further stormwater and wetland mitigation design. Completed Traffic Analysis. Completed preliminary investigation into seismic retrofit requriements for the wideing of the SB SR 167 structure over SR 18. Submitted channelization plan for review. For more project information see the project web page.

Design Construction Impacts
Meeting storm water detention, culvert replacement and floodplain storage requirements is extremely difficult in this location. This project will use innovative methods to meet requirements and these methods will require state and federal approval and additional right of way. The bridge that crosses over SR 18 is being widened and may require seismic retrofit.

|
Environmental Impacts / Compliance
An environmental document (DCE) is being prepared for submittal to the regulatory agencies in Fall 2008
|
Impacts to Traffic
The project will increase capacity and improve traffic operations by extending the HOV lanes through a major congestion point, the SR 167/SR 18 interchange. Construction will require lane closures during non-peak hours and may require peak hour lane closures.
