Residents in North Redmond have been inquiring about the status of 172 Ave NE, and when it might be open to through traffic [to 124th Street.]
Currently 172 Ave NE remains closed, with a gate at NE 124 Street (Redmond City limits), but is accessible to emergency response vehicles as well as pedestrians and bicyclists.
172 Ave NE will open to general vehicular traffic when the following conditions are met:
The intersection of 162 Place NE and NE 124 Street meets warrants for a traffic signal, which will happen when enough residential units are built and occupied in North Redmond to generate sufficient traffic volumes.
Funding is identified for a traffic signal and left turn lanes at 162 Place NE and NE 124 Street and the project is constructed. (This intersection is currently owned by King County.)
Traffic calming is completed on the corridor between NE 111 Street and NE 128 Street. Propoased traffic calming will be coordinated with area residents and King County.
As a side note, the existing gate was recently damaged by an unknown vehicle. The City is working with a local contractor to have the gate repaired.
Based on the construction status of the two subdivisions on 116th I'm guessing 172nd won't be punched through until around 2020. This punch-through will add to already heavy Avondale and 166th Av. volumes. by
