23 Dec Changes to SR99 Tunnel placement in Pioneer Square

According to WSDOT’s website, the Alaskan Way Viaduct replacement team is discussing “new north and south portal locations and a potential new route for the proposed bored tunnel.”

At the south end (in Pioneer Square),  the entrance to the tunnel could be moved a block west to Alaskan Way, reducing the impact on our historic neighborhood. The original plan called for a portal entrance on 1st Avenue; moving the location will also change the route for the tunnel.

According to the DJC, “the revised alignment would begin on Alaskan Way South and move toward First Avenue near Yesler Way. The tunnel would turn north near Stewart Street and end at Sixth Avenue North near Harrison Street.”

This is a really great thing, but according to PSCA, our neighborhood still needs to be aware of any progress and stand up for itself to avoid 1st Ave becoming a big freeway. I’ll post any updates as I hear about them.
