Washington State Route 509

Washington State Route 509 is an approximately 35 mile state highway spanning from WA 99 in Seattle southwest to I-705 in Tacoma.  The routing of WA 509 varies from freeway segments, to major surface arterial roadways and even to coastal bluff roads.  While certainly not the fast way between Seattle and Tacoma it does serve as a semi-scenic alternate to the topical slog of I-5.






I began my drive on WA 509 heading southbound.  With that being the case I approached WA 509 on WA 99 southbound.  WA 509 is signed as "To" route via WA 99 as it crosses over the Duwamish Waterway.  WA 99 crosses the Duwamish Waterway on the First Avenue South Bridge.  The two spans of the First Avenue South Bridge were completed in 1956 and 1998, both are draw spans.   Oddly WA 99 traffic is directed to exit on the First Avenue South Bridge while WA 509 continues ahead as a freeway.










The next major junction on WA 509 southbound is at WA 518 near SeaTac International Airport.  WA 518 connects SeaTac International Airport and I-5 while WA 509 continues to Normandy Park in addition to Des Moines.







WA 509 becomes a surface route in southern Burien as the freeway segment ends.  WA 509 runs on Des Moines Memorial Drive westward where it turns south again on 1st Avenue.  This particular segment of WA 509 is incredibly poorly signed and I had to refer to street blades to ensure that I was actually on the highway.





WA 509 straddles Normandy Park and Des Moines on 1st Avenue before turning over Des Moines Creek on 216th Street.





In downtown Des Moines WA 509 runs on Marine View Drive, again there is almost no indication it is a state highway.




WA 509 meets WA 516 at Kent-Des Moines Road.  WA 509 technically multiplexes WA 516 east to WA 99 at Pacific Highway. 


WA 509 splits away from WA 99 at Dash Point Road in Federal Way.





WA 509 becomes a coastal bluff highway on Dash Point Road.  The roadway is curvy but nothing too extreme as it continues westerly to Dash Point State Park.













WA 509 crosses a stream in Dash Point State Park enters Pierce County and the community of Dash Point.






As WA 509 enters the City of Tacoma there is a overlook of Commencement Bay, the Port of Tacoma and downtown Tacoma.




WA 509 continues west along the waters of Commencement Bay where it becomes a freeway again at Port of Tacoma Road. 









WA 509 continues west over the Puyallup River and the Thea Foss Waterway on the 21st Street Bridge to a terminus with I-705 in downtown Tacoma. 






Before the 1964 Washington State Highway renumbering the route of WA 509 was assigned two different numbers; WA Primary State Highway 1V and 1K.  WA Primary State Highway 1V carried traffic from downtown Tacoma to US 99 in Federal Way.  WA PSH 1V actually continued along the coastline from Pacific Highway to WA PSH 1K in Des Moines.  WA PSH 1K ran from US 99 in Des Moines to US 99 in Seattle.  Both WA PSH 1V and 1K were both created in 1937, the map below from 1956 shows them as they were before the 1964 renumbering.


Update 6/1/18:  According to thefraze_1020 on AAroads the alignment of WA 509 was shifted onto a multiplex of WA 516 and WA 99 in 1992.

Sierra Vista Scenic Byway Part 1; Sierra National Forest Route 10

This past month I partook in camping out in Sierra National Forest.  My route into Sierra National Forest was on Forest Route 10 which is a segment of the Sierra Vista Scenic Byway.


Sierra Vista Scenic Byway is an 82.7 mile loop of much of Sierra National Forest along the western flank of the San Joaquin River basin.  The Sierra Vista Scenic Byway was created in 1989 from the following Forest Routes:

-  From CA 41; northeast on Road 632/Sky Ranch Road to the boundary of Sierra National Forest where the road becomes Forest Route 10/Forest Road 6S10.
-  Forest Route 10 north of Fresno Dome to where the designation moves to Forest Road 6S10X/Beasore Loop.
-  Forest Route 10 to Forest Route 7/Beasore Road on Forest Road 5S07.
-  Forest Route 7 northeast Forest Route 81/Minarets Road on Forest Road 4S81 at Clover Meadow.
-  Forest Route 81 to the boundary of Sierra National Forest where it becomes Road 225 near North Fork.

The Sierra Vista Scenic Byway has several lengthy dirt segments in …

Chisholm Ferry/Bridge Location and early Legislative Route Number 10

This past month while viewing the site of Chisholm Ferry along the Kings River of Kings County I noticed that route being illustrated resembled an early Californian State Highway.  My suspicions proved correct as the location of Chisholm Ferry was part of the original alignment of Legislative Route Number 10; a precursor to California State Route 198.


The Facebook in question above was posted on the Antique Images from the Collection of Michael J. Semas and can be viewed below:

Michael J. Semas on Chisholm Ferry and Bridge

The location of Chisholm Ferry is located just south of Jackson Avenue/Old CA 198 on the Kings River about 4 miles west of Lemoore near Avenal Cut-Off Road.  This particular section of the Kings River was once the northern most extent of Tulare Lake.

Tulare Lake was once the largest fresh water lake west of the Great Lakes by surface area.  Tulare Lake was first surveyed at an approximately 570 square miles in 1849 and was later surveyed to be 690 square miles in …

California State Route 118

This past month I drove the entirety of California State Route 118 from Ventura County east into Los Angeles County.


CA 118 is a major 47 mile State Highway which begins in the City in Ventura County and traverses east into Los Angeles County by way of Simi Valley and Santa Susana Pass.  From Santa Susana Pass CA 118 continues eastward through San Fernando Valley within the City of Los Angeles and terminates at Interstate 210.  CA 118 contains within it's right-of-way some of the most historic highway corridors in California history.

The precursor route of CA 118 was Legislative Route Number 9 which was first added to the State Highway System during the First State Highway Bond Act of 1909.  The original definition of LRN 9 was from San Bernardino westward to LRN 4 in San Fernando. LRN 9 was extended westward to LRN 2 near Montalvo (modern day Ventura) in 1933.

In a August 1934 Department of Public Works Guide the Signed State Highways were announced.  CA 118 was announced to be a…
