Construction on the Parkway began in early January 2013. Construction Ahead (pdf), a newsletter about the West Lake Sammamish Parkway Project, was mailed to area residents in late January.

Starting Tues., March 19, West Lake Sammamish Parkway will be closed to southbound traffic from Southeast 34th Street to just north of the I-90 roundabout until October. The detour will redirect southbound traffic onto SE 34th Street. Northbound traffic will be permitted but significant delays are still likely. All businesses will remain open during construction. For current traffic conditions, follow the Transportation Department's Twitter feed (@BvueTrans) and check the traffic advisories page.
Prior to the detour starting, it is strongly recommended that motorists find alternate routes (pdf) to traveling on West Lake Sammamish Parkway between Interstate 90 and Southeast 34th Street. Delays of 15 minutes or more are possible through the construction zone.
The West Lake Sammamish Parkway Project will enhance safety for pedestrians, bicyclists and drivers by providing a multi-use trail along the west side of the arterial, and it will restore the existing pavement while maintaining the distinct character of the area. The proposed construction plan breaks the roadway into five approximately mile-long segments.
The first segment of the project is located between Interstate 90 and Southeast 34th Street. The city began construction of Phase 1 in early 2013. The scope of work includes the construction of a 10-foot wide multi-use path on the west side of the street, a four-foot shoulder on the east side, and two general-purpose travel lanes (one northbound and one southbound).
