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

Image
By
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

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

By
In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l

Ghost Town Tuesday; Mannfield, FL and the stairway to Hell

By
Back in 2015 I went searching the Lecanto Sand Hills for the original Citrus County Seat known as Mannfield.  Unlike Centrailia in Hernando County and Fivay in Pasco County I did find something worth seeing. Mannfield is located in the Lecanto Sand Hill section of Withlacoochee State Forest somewhat east of the intersection of Citrus County Route 491 and Mansfield Road. Mannfield was named after Austin Mann and founded in Hernando County in 1884 before Citrus County Split away.  In 1887 Citrus County was split from northern Hernando County while Pasco County was spun off to the south.  Mannfield was selected as the new Citrus County seat due to it being near the county geographic center.  Reportedly Mannfield had as many as 250 people when it was the County Seat.  The town included various businesses one might include at the time, even a sawmill which was common for the area.  In 1891 Citrus County voted to move it's seat to Inverness which set the stage for the decline of M

The National Road - Pennsylvania - Great Crossings Bridge and Somerfield

By
West of Addison, US 40 crosses the Youghiogheny River at what once was the town of Somerfield.  When crossing the current modern two lane bridge, you many not realize that it is actually the third to cross the Yough at this site.  The first - a stone arch bridge - was known as the Great Crossings Bridge.  Built in 1818, this three arch bridge was part of the original National Road.  The name Great Crossings comes from the men who forded the Youghiogheny here - George Washington and George Braddock. (1)  If you cross the bridge at the right time, this historic bridge and what was once the town of Somerfield will appear out from underneath this massive man-made lake.

The Great Crossings Bridge was located in the town of Somerfield.  Somerfield, originally named Smythfield until 1827, would develop as a result of the National Road.
