Washington State Route 599



Washington State Route 599 is a 1.75-mile freeway entirely contained within the City of Tukwila located in King County.  WA 599 is a north/south route connecting I-5 to WA 99 and is former alignment of US Route 99.

This blog is part of the larger Gribblenation US Route 99 Page.  For more information pertaining to the other various segments of US Route 99 and it's three-digit child routes check out the link the below.



Washington State Route 599

There isn't much to WA 599 as a route but there are some neat signs like this WA 599 "Begin."


The Light Rail from SeaTac International Airport crosses above WA 599 near Marginal Way.


There are only two exits on WA 599; the first is at Interurban Avenue while the second is at Tukwila International Boulevard.  Tukwila International Boulevard is another former alignment of US 99 which predated the freeway WA 599 runs on now.


North of Tukwila International Boulevard the route becomes WA 99 and WA 599 ends.  There is a much better sign assembly explaining the change south of this one, but I wasn't expecting it and missed the photo.


Interestingly there is a gap in WA 99 from WA 518 north to the terminus of WA 599 which is spanned but Tukwila International Boulevard.   The routing of what is now WA 599 was constructed in the late 1950s and was part of Primary State Highway 1 WM (West Marginal).  When the route had been completed US 99 switched alignments apparently onto a multiplex of I-5 and may have been once been signed as US 99T.  The route has been designated at WA 599 since 1971.  This older map of the state highway system from 1956 shows how US 99 used to flow through from Tacoma through Seattle before the construction of I-5.

Edit 5/13/18:  I was shown a 1970 map scan of downtown Seattle by Flickr user Arthur Allen showing the routing of WA 599 shown as WA 99T.  The map scan can be viewed here at the following link:

Rep. Sue Myrick's letter to Gov. Easley and Sect. Tippett published in Charlotte Observer

US. Representative Sue Myrick's (R-Charlotte) letter to North Carolina's Governor Mike Easley and NC Transportation Secretary Lyndo Tippett was published in the Friday, November 30th edition of the Charlotte Observer . Why are we delaying the completion of 1-485 in Charlotte again? I read in The Charlotte Observer how rising prices of materials are leading to the delay. Why didn't these same rising costs delay the loops in Fayetteville and Wilmington? Why are we building loops in Fayetteville and Wilmington before we complete the one in Charlotte? We were working on the one in Charlotte back when I was mayor. That was 20 years ago! ... Last I looked Charlotte was the largest city in the state. There seems to be no recognition of that fact in Raleigh. No recognition that we are at a standstill with traffic. No recognition that we have a traffic problem. Nor is there any recognition of the fact that the state DOT utterly botched up the southern leg of our yet to be completed ...

New River Gorge National Park & Preserve - Sandstone Falls

The New River, which runs through New River Gorge National Park & Preserve, is best known for its dramatic rapids and whitewater adventures.  Those features begin at one of the river's widest points: Sandstone Falls. From the Sandstone Falls Boardwalk a look at just a small part of the falls. Though the vertical drop of roughly 20 feet is less than many other well-known waterfalls in the state, the falls' expanse, where the river approaches 1500 feet wide, makes Sandstone Falls impressive.   The Boardwalk Trail leads to a better vantage point of the overall falls. It is a great spot for photography, fishing, or laying out in the sun. Access to the falls is relatively easy: from Hinton, cross the New River on Highway 20, then turn right onto CR 26 and follow New River Road to the Sandstone Falls Parking Area. The Island Loop Trail is a short detour off the Boardwalk Trail and shows a quieter side of the area. At Sandstone Falls, you will find a variety of activities fr...

I-90 in Albany, New York and the Berkshire Spur

Today's Albany Times Union has a segment in their weekly Getting There? column that explains some of the history behind how I-90 is designated in the Albany, NY area as well as the Berkshire Spur. The long and short of the article was that I-90 was originally designated on the unsigned portion of the Berkshire Spur, but as free I-90 was built, the designation was moved onto the free portion of road. Additionally, there were talks in 1999 between state and federal officials about the possibility of moving I-90 back onto the unsigned portion of the Berkshire Spur, while extending I-88 onto what we know as free I-90. There would have also had been an I-88/I-90 multiplex between Rotterdam and Albany as a result. http://www.timesunion.com/AspStories/story.asp?storyID=916307
