Spokane Street Bridge and West Seattle Bridge

Below in this photo the Spokane Street Bridge and West Seattle Bridge can be seen rising above Harbor Island and the Duwamish River.






The Spokane Street Bridge is a 1991 concrete swing bridge which replaced the earlier Old Spokane Street Bridge (AKA North Bridge) which was completed in 1924.  The Spokane Street Bridge serves as the lower level of the dual structure West Seattle Bridge, the longest span is 480 feet.  More information on the Old Spokane Street Bridge can be found on Bridgehunter.com

The completed Old Spokane Street Bridge can be seen on the 1924 City map of Seattle.

Interestingly the 1924 Old Spokane Street Bridge was proceeded by two other bridges.  The previous bridge to the 1924 span was the Third Spokane Street Drawbridge which was a truss span completed in 1917.  Previous to the 1917 the span there was an earlier truss which crossed to what was presumably Harbor Island when it was under construction in 1907 called the Second Spokane Street Bridge.

Historylink.org actually has an article on both the Third Spokane Street Bridge the Second Spokane Street Bridge.

The West Seattle Bridge was under construction from 1981 to 1984 and was meant to relieve traffic congestion on the 1924 Spokane Street Bridge.  The West Seattle Bridge is Sectional Cantilever Bridge that is 2,607 feet long and has a maximum clearance of 140 feet.  The West Seattle Bridge essentially part of a freeway grade west from I-5 which crosses a junction with WA 99 before leveling off to a street grade near SW Genesee Street.

When I was driving through the area I met Spokane Street at Harbor Avenue and continued east to WA 99 on the Spokane Street Bridge.  The Spokane Street Bridge provided views of the substructure of the West Seattle Bridge.

California State Route 190; a Trans-Sierra Highway that could have been

This past week I decided to take a small scale road trip on California State Route 190 from CA 99 east to the unbuilt section over the Sierra Nevada Range.  While I was in for what turned out to be a fun drive following the course of the Tule River watershed what I found researching the back story of CA 190 was one of the most complex and unusual stories of any California State Highway.  Given that I had a ton of older photos of the eastern segment of CA 190 in the Mojave Desert of Inyo County I thought it was time to put something together for the entire route. The simplified story of CA 190 is that it is a 231 mile state highway that has a 43 mile unbuilt gap in the Sierra Nevada Range.  CA 190 is an east/west State Highway running from CA 99 in Tulare County at Tipton east to CA 127 located in Death Valley Junction near the Nevada State Line in rural Inyo County.  The routing CA 190 was adopted into the State Highway system as Legislative Route 127 which was adopted in 1933 acc

I-73/I-74 and NC Future Interstates, Year in Review 2022

Another year over, already? 2022 turned out to be quite the year if you are a fan of new interstate routes, and it wasn't bad for some long standing favorites. As per the tradition, I will review what happened with I-73 and I-74, and then the other new and future interstate routes in North Carolina... Work continued on the one segment of I-73 under construction, the I-73/I-74 Rockingham Bypass. As of the beginning of December, work was getting close to being 2/3 complete at 60.1%. Progress could be seen from US 74 on constructing of the future interchange at the Bypass's southern end. Here's a look from US 74 East in September from Google Maps Street View: Here's a photo from US 74 West taken last week by David Gallo: Work is now scheduled to be completed in October 2025, though the road itself could open earlier that year.  Progress on I-74 earned more publicity in 2022 with the opening of 7.5 more miles of the Winston-Salem Northern Beltway from US 311 (Exit 49) to NC

Interstate 605

Interstate 605 is a 27.4-mile freeway located in the Los Angeles Metropolitain Area.  Interstate 605 begins at Interstate 210 near Duarte and terminates at the Interstate 405/California State Route 22 junction to the south near the boundary to the city of Long Beach.  Interstate 605 is known as the San Gabriel River Freeway and has three unconstructed miles which would extend it south to California State Route 1 near Seal Beach.  Much of the corridor of Interstate 605 was built up from what was the original California State Route 35.  The blog cover photo is taken from the July/August 1964 California Highways & Public Works which featured the initial segment of Interstate 605 to open between Whittier Boulevard and Peck Road  Part 1; the history of the San Gabriel River Freeway and Interstate 605 The origin of what is now Interstate 605 begins during 1933 with the addition of Legislative Route Number 170 (LRN 170) to the State Highway System.  The original definition of LRN 170 was
