From the 1950's
to the 1980's, there was a proposal to build a 4-lane expressway paralleling
PA Route 48. This proposed highway was officially known as the "North-South Parkway", but locally known as the "New 48". Sadly, this
route never came to be; however, it is the predecessor of another highway,
Mon-Fayette Expressway. The "New 48" was a highly debated route that really never got beyond the planning stages.
There are very few remnants of construction left.
History: Originally proposed
in the post-war Pittsburgh, the "New 48" was a lot of talk, but it really never saw much work done. Most of the discussion, planning, land acquisitions and right-of-way clearing occurred in the 1960s. The "New
48" would also have gone by the term "North-South Parkway". This was
the term for the highway used in White Oak: A Master Plan done by the Pittsburgh Regional Planning Commission in 1960. (1)
Coming back from my Great Lakes Trip the other day I encountered this sign goof at Fresno-Yosemite International Airport which incorrectly displays US Route 99.
That little US 99 sign was the inspiration I needed to start tracking all the former alignments through the City of Fresno. Fresno in general has had a huge shift in highway layouts over the decades which is something I intend to finish with California 41 and 180 perhaps later this month. Based off my research I came with the following three maps progressing northward through Fresno showing every iteration of US 99 before it was downgraded to a State Highway in 1967.
Essentially the route alignment history of US Route 99 in Fresno is as follows.
Progressing northward into Fresno US Route 99 would have followed:
- Railroad Avenue
- Cherry Avenue
- Broadway Street
- Divisadero Street
- H Street
- Belmont Avenue
- Golden State Avenue
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. (1)
Flinn along with James J. Booth would found the Booth and Flinn construction firm in …
