Some new details from the current online open house.
https://engage.wsdot.wa.gov/sr167completionproject/First, unless every diagram is wrong, the “509 Spur” moniker is being dropped, and the whole freeway will be called 167. So, exiting I-5 southbound, you can now stay left towards “NORTH, Puyallup”, or “SOUTH, Tacoma”. Brilliant.
Second, Valley Ave is going to be a roundabout. Dogbone design. The southerly ramps will be constructed in the future.
Third, the interchange at Meridian will now be a DDI. With what appears to be a very complicated southern intersection.
Fourth, the intersection at Alexander Ave is being redesigned into a single non-split intersection. Based on the roadway layout, it seems WSDOT is giving up on building any overpass here anytime soon.
Here is a video, which many of you will find very interesting:
