Road closure on 187th Avenue Northeast near Sammamish city limit
This is a City of Redmond development project.
A City of Redmond development project requires the temporary closure of 187th Avenue Northeast adjacent to Sammamish neighborhoods to accommodate work for The Cove short plat located in Redmond. Their contractor will close 187th Avenue Northeast between East Lake Sammamish Parkway Northeast and Northeast 53rd Street. A detour will be in place along East Lake Sammamish Parkway Northeast and Redmond-Fall City Road NE (SR 202) to manage traffic during this period. This closure may impact Sammamish local traffic, including NE 54th Place Northeast and NE 55th Street. The closure is tentatively scheduled to begin on Wednesday, Jan. 29, 2025, and is expected to last for approximately eight working days. Work hours will be from 7 a.m. to 4 p.m., Monday through Friday. For more information about this project, please visit the City of Redmond’s project webpage.
