Ramp Stubs/Unused Highways in Washington

<< < (2/5) > >>

Most of it comes down to that prior to the 1960s, there was no single roadway that spanned the length of the Island.  As a result, when they did build "the highway", as 525 and 20 are called, a lot of old routes were bypassed, and the old routes were either stubbed or turned into local roadways.  Later on, most of those, which were at angles other than 70-120 were modified to provided better sight lines, traffic use be dammed.  Few of these are actually visible on Google Maps, but Historic Aerials helps with a lot of the information.

The little village/community of Clinton.  The highway bisects the grid in this community, and has since at least the 1940s.  The current Commercial Ave, which is currently curved, used to meet at Wilson Rd/Humphrey Rd.; Frost Ave. and Central Ave used to be a single street, in fact, until the mid-90s, it was just called Central Ave.  The section of Deer Lake Rd. used to Harding Ave, which now only exists as a short stub road (the post office's address was on Harding Rd. until around 2000), and Deer Lake Rd, was routed down Central Ave. until the late 90s.  Brighton Beach Rd., and the Highway used to merge were the current Bob Galbreath intersection is, as prior to the construction of the current ferry terminal area at Columbia Beach, the mosquito fleet dock was at the base of Brighton Beach Rd., not that there is much evidence of that any more.  There is also a vestigial road, legally one-way and lined, but no longer signed as such in the former ROW of the old Commercial Ave.

Up North, it is fascinating, to me, to look at the tree lines, and where roads exist on either side of Ault Field (NAS Whidbey), to show the former routings of Goldie Rd and Oak Harbor Road over to the other side of the valley (both carried 1-D back in the day).  Also, if you look at Oak Harbor, you will see that SR 20 heads North, then veers NE after about 8-10 blocks.  Oak Harbor Rd. continues in the Northern direction, as I said, it used to carry I-D, and was still connected to SR 20 until about 1993, when it was turned into a pedestrian only connection.

I have plenty more, mostly the roads that were used for the old routing that are still in use, the few that are no longer used for any traffic, and the others that are now trail heads and other parks.

yeah... sorry about that. That was my fault.

Just stumbled across a ramp as I was browsing google maps but since it's just closed as opposed to being a stub I'll post here since it fits better.

It's at the 509 interchange with S Cloverdale St:,-122.3334963,375m/data=!3m1!1e3

Interestingly, old streetview shows a sign in the gore identifying it as a "Restricted Ramp" but there is no indication of what the restriction was that I can see. What's more, the ramp simply merges back to 509, so it doesn't seem particularly useful. The only thing it accomplishes is a small queue jump if traffic is backed up on the mainline. Does anyone have any idea what this ramp may have been for?

Only thing I could think of would be for the bus lines that run on WA 509 -- OSM shows three, but all are mapped on the mainline. The ramp would make sense if any of them exited at Marginal/WA 99 south at the next exit, but the mainline is a four lane facility, making that ramp rather redundant for the upcoming aux lane, and none of the bus lines exit at Marginal anyway.

Another now-rare stub around here is the Sea-Tac Airport freeway northbound lanes, abandoned after wrapping those lanes around Link light rail.  It also turned a former onramp into an offramp.  Gee, that's not confusing.  :confused:
