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 dropout, 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. (1)

Flinn along with James J. Booth would found the Booth and Flinn construction firm in 1876.  In a time when 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.

Good article. My great grandfather was William Flinn. I published a book about Hartwood and I cover Booth and Flinn in good detail. My book can be seen here: http://www.reflectionsofhartwoodbook.com

I have traveled Route 8 (North and South) for years and always thought the FLINN spelling was incorrect. I am a lifelong Pittsburgher and never knew much of what this article covered about William Flinn. I vowed I am going to try to learn more about the history of our great city. And I plan to look at the book on Hartwood, too.

Did Caltrans just kill the G26 cutout US Route shields?

The US Route System was formally created by the American Association of State Highway Officials during November 1926.  Through the history of the system the only state to which has elected to maintain cutout US Route shields has been California.  The G26 series cutout US Route shields have become a favorite in the road enthusiast hobby and are generally considered to be much more visually pleasing than the standard Federal Highway Administration variant.  However, the G26 shield series appears to have been killed off on January 18, 2026, when Caltrans updated their Manual of Uniform Traffic Control Devices.  This blog will examine the history of the US Route shield specifications in California and what is happening with the 2026 changes.  The blog cover photo is facing towards the terminus of California State Route 136 and at a G26-2 specification US Route 395 shield.  In the background Mount Whitney can be seen in the Sierra Nevada range.   ...

May 2023 Ontario Trip (Part 3 of 3)

  Over the years, I have made plenty of trips to Ontario, crisscrossing the southern, central and eastern parts of the province. Living in Upstate New York, it's pretty easy to visit our neighbor to the north, or is that our neighbor to the west? Ottawa is one of my favorite cities to visit anywhere in the world, plus I've discovered the charm of Kingston, the waterfalls of Hamilton (which is on the same Niagara Escarpment that brings us Niagara Falls), the sheer beauty of the Bruce Peninsula, and more. But I hadn't explored much of Cottage Country. So I decided to change that, and what better time to go than over Memorial Day weekend, when the daylight is long and I have an extra day to explore. On the third and final day of my trip, I started in Huntsville and made my way through Muskoka District and Haliburton County, passing by many lakes along the way. I stopped in towns such as Dorset, Haliburton and Bancroft before making a beeline down to Belleville and then over th...

Ghost Town Tuesday; Nichols, FL

A couple years ago I spent a lot of spare time exploring phosphate mining ghost towns in the Bone Valley of Polk County, Florida.  One ghost town in particular called Nichols on Polk County Route 676 west of Mulberry caught my eye due to a relative lack of documentation on ghosttowns.com. Nichols was created in 1905 during the early phosphate mining boom in the Bone Valley region.  For the time Nichols was unusual since it had company housing in the Nichols Mine site and private residences outside the gate.  Nichols is only about two miles west of Mulberry which probably made it a somewhat reasonable commute even by the wonky standards of the early 20th Century.  Most of the Bone Valley region was relatively remote which made commuting or homesteading impractical which is why there are so many ghost towns in the area.  The company housing section of Nichols was phased out and abandoned by 1950. The Nichols town site is largely abandoned and could "possibl...
