The William Flinn (not Flynn) Highway - Pittsburgh's Misspelled Street

For decades if you traveled along PA Route 8 in Pittsburgh's North Hills suburbs, you would have noticed signs that read "William Flynn Highway" at every intersection.  Even today, many businesses and residences have their addresses listed as XXXX William Flynn Highway.  However, it's not William Flynn Highway, it is William FLINN Highway - and the gentleman who it is named for has a long and storied past in Pittsburgh's infrastructure history.

William Flinn was born in England in 1851; however later that year, his family emigrated to the United States and would settle in Pittsburgh.  A 10 year-old school drop out, Flinn grew interested in politics and would join the Allegheny County Republican Party in 1877 as a ward commissioner and a seat on the Board of Fire Commissioners.  Flinn would serve in the Pennsylvania State House of Representatives and Senate from 1877 to 1902.

Flinn along with James J. Booth would found the Booth and Flinn construction firm in 1876.  In a time where political power brokering was commonplace, Flinn would partner with Christopher Magee to further their ambition of wealth and power.  As a result of his political connections with Magee, Flinn would see his company be awarded major infrastructure projects within the Pittsburgh region in the late 19th and early 20th centuries.  Booth and Flinn constructed three of Pittsburgh's major tunnels - the Mount Washington Transit Tunnel (1904), Liberty Tunnel (1924), and Armstrong Tunnel (1927) - among many other projects. (2)  The firm also built the Holland Tunnel that links New York City and New Jersey.

Flinn died in 1924 in Florida at the age of 72.  Flinn would be buried in Homewood Cemetery.  Hartwood Acres, the Allegheny County park known for its Christmas festivities, was formerly the estate of his daughter, Mary. The highway that bears his name was dedicated one decade after his death in 1934.  However, in 2001, the state legislature dedicated the Allegheny County segment of the highway after former PA State Representative, Rick Cessar.  In 2013, PENNDOT finally corrected the spelling of Flinn's last name on street signs in Allegheny and Butler Counties.

The William Flinn Highway is better known in Pittsburgh's North Hills.  However, it was named such throughout Allegheny County.  South of Pittsburgh, it is better known as Old Washington Pike which at one time was US 19 and prior to that part of PA Route 8.  Along the Old Washington Pike at the Allegheny/Washington County Line there is a now nearly 85 year old stone monument honoring William Flinn and the highway that bears his name.

Old US 101; the San Juan Grade

While researching maps for California State Route 183 I noticed something interesting on the 1935 County Highway maps for San Benito and Monterey County.  From what it appeared it seems that there used to be a state highway running from US 101 south on San Juan Highway, through San Juan Bautista, south over the San Juan Grade to Salinas.  It turns out what I discovered was an a very old alignment of US 101 which was replaced by 1932.

The information relevant to the history of US 101 over the San Juan Grade is as follows:

-  The San Juan Grade was built in 1915 which presumably replaced Old Stage Road from Salinas to San Juan Bautista.  Presumably this was part of alignment adopted as Legislative Route 2 from San Francisco south to San Diego in 1909.  This history can be seen on 1931 edition of the California Highways and Public Works Journal and on

-  By 1926 the San Juan Grade became part of US 101.  The San Jua…

The Tioga Pass Road

Last Summer the Tioga Pass Road over the Sierras in Yosemite National Park opened late due to the heavy snow pack during the previous winter.  Approaching the start of July the Park Service finally had cleared Tioga Pass, I headed up shortly after the 4th of July holiday during a lull in the tourist season.

The Tioga Pass Road runs from the Big Oak Flat Road east to US Route 395.  The Tioga Pass road is largely within the boundary of Yosemite National Park but is also partially on California State Route 120 east of the Tioga Pass entry station to US 395.  The Park Service maintained portion of the Tioga Pass Road serve as a implied connection between the two segments of CA 120.  The Tioga Pass Road is the highest road mountain pass in California with Tioga Pass which lies at 9,945 feet above sea level.

The Tioga Pass Road is very old with the eastern section up Lee Vining Canyon to the Tioga Mine being built in 1883.  The connecting section of the Tioga Pass Road from Big Oak Flat R…

California State Route 49, The Golden Chain Highway (CA 16 north over Yuba Pass to CA 89)

After completing California State Route 124 I took CA 16 to the eastern terminus to start my first Trans-Sierra route; California State Route 49/Golden Chain Highway over Yuba Pass.

As stated I joined CA 49 from the eastern terminus of CA 16 in Amador County.  CA 49 actually begins in Madera County to the south in Oakhurst at CA 41.  CA 49 is about 295 miles long and travels most of the traditional 1849 Gold Rush Country north from Oakhurst to CA 70.  If you want history and old towns then CA 49 is one of the best routes on the West Coast to see both.

To the north of CA 16 the next major junction is Signed County Route E16 in Plymouth which is on Shenandoah Road.  E16 is a 33.2 mile route which travels northeast to US 50. 

Plymouth dates back to the 1850s and is mostly known for a winery that dates back to 1856.  These photos are from Main Street looking west.

CA 49 generally is very rural and doesn't deviate much from when it was first signed back in 1934.  While CA 49 isn'…
