Update as of 1/29:

Due to unforeseen circumstances, including construction delays caused by necessary third party utility relocations and inclement weather, the City of Sammamish Public Works Department has determined the road opening by end of January is not feasible.

The City of Sammamish has looked at options to hasten the construction or partial openings, but has determined in an abundance of caution that these options are not safe nor realistic due to weather events and fiscal constraints.

Upon reviewing the contractor's updated and current schedule, and the status of utility relocations, the bridge and roadway are now scheduled to be opened to traffic on May 1, 2021.

We understand and apologize for this inconvenience and thank you for your continued patience as we work to improve the City’s traffic flow.

Daytime Project work hours are 7:30 a.m. to 5 p.m., Saturday Work Hours 9:00 a.m. – 6 p.m.
