Puget Sound Gateway Program (WA-167 and WA-509 Extensions)

<< < (9/10) > >>

Plutonic Panda:
Progress is being made on the SR-167 project:

--- Quote --- The new bridge and nearby roundabout to SR 99 being constructed by Guy F. Atkinson crews are essential steps for the SR 167 Completion Project, which will build 6 mi. of highway and complete the unfinished SR 167 corridor near Tacoma.

The SR 167 Completion Project is part of the estimated $2 billion Puget Sound Gateway Program that includes the SR 509 Completion Project near Seattle. Both projects complete two crucial unfinished links in Washington State's highway and freight network.

When I posted the old SR 509 plans on the Never Built thread, CompDude mentioned that you could see the undeveloped path of the freeway on Google Satellite View.  I noticed that on the overlay of current streets I could see SR 99 was swinging out of the way where 509 is going to cross under it, so that meant they were working on the undercrossing.  They are building Link Light Rail along here too, which is crossing above 99 while the new freeway is crossing  under.  These posts you see here are the only new supports put up around here.  The path a few blocks behind the photo to the end of the line is still unpopulated.  They're also digging a trench along I-5 to the south, but I don't know if that's for this freeway yet or just for the light rail.

A new video of the conceptual design of "SR 509 Spur" between I-5 and the Port of Tacoma:

One of the interchanges looks to be a single-point urban roundabout, which looks fun.

The only good it serves is to lead to the state park. But this doesn't seem to be a necessity anymore (i.e. Saltwater State Park in Des Moines). This whole section is a circuitous route and sporadically signed. I don't think it even is maintained by WSDOT; it looks more like county signage and maintenance. Likewise, the portion of 509 that doglegs up to 1st Ave S at the end of the freeway in Burien and winds down to Des Moines is pointless as well. That could go bye-bye, especially when the freeway is extended to I-5. If that were the case, SR-516 would end all alone. So either leave that, or extend it up Des Moines Memorial Drive to the 509 freeway.

I've thought for a while now that the two sections of SR 509 should be severed and the northern part renumbered as either 511 or 517.

They're pretty common in the UK. Maybe they'll gradually get more popular here, like traditional roundabouts (excluding dogbone interchanges, since those are a bit different in geometry)?
