The story behind the ghost ramps around Pittsburgh International Airport

The roads around Pittsburgh International Airport have a lot of history and intrigue.  The growth of the airport and resulting land acquisitions has changed the routing of many roads in Western Allegheny County.  As the airport grew and traffic around the airport increased, the need for new roads would also change the landscape.  Of course, the fact that this is Pittsburgh means there were also plans for highways that never came to be.  Two of these never built highway plans, the Beaver Valley Expressway (BVE) extension and the full-speed connection to the Southern Expressway at Flaugherty Run Road have traces - specifically ghost ramps - of highways that never came to be.

Beaver Valley Expressway Extension:

For close to three decades this unused piece of roadway along the southern end of Beaver Valley Expressway puzzled Pittsburgh area travelers.  Located near the current-day maintenance hangers for Pittsburgh International Airport, this concrete stub of a highway was supposed to be the start of a bypass of the then highly congested terminal entrance at the intersection of the Airport Parkway and Beers School Road.  This freeway bypass was to be a continuation of the Beaver Valley Expressway which would tie back into the Airport Parkway near the current Thorn Run Road interchange.

The need for this bypass was the continued growth of what was then Greater Pittsburgh International Airport.  The Airport Parkway was constructed in the 1950s as part of the Penn-Lincoln Parkway project.  The Monroeville to Airport east-west link allowed for direct connection from the new airport to downtown.  The Airport Parkway ended in grand fashion at the entrance to the airport's main terminal at the intersection of Beers School (now University Blvd.) and Hookstown Grade (now Stevenson Mill) Roads.  

Construction of the Beaver Valley Expressway, which would eventually run from Sharon/New Castle through Beaver County to the airport, would begin near the airport in the late 60s and open by 1972. (1)  By then the congestion around the airport terminal had become an issue.  With new thru-traffic volumes to be added as a result of the new freeway, plans were made to extend the BVE as a bypass of the terminal and connect with the Airport Parkway just south of the terminal.  While the plans for the expressway's extension were being made, a temporary four lane connection from the Flaugherty Run Road to Beers School Road was constructed. 

The routing of the proposed bypass was to basically parallel the existing Airport Parkway and temporary connection to the North.  According to Bruce Harper the expressway would have the following routing (2):
As planned, the Expressway would have left the Parkway West somewhere in the vicinity of Montour Heights Country Club (now the Cherrington office park), just south of the current Thorn Run interchange.  The new road would have been to the north of the (now vacant) parking lots across the Parkway from the airport terminal (through the area now populated by the office park and Royce Hotel).  It would have come up
through Port Vue Drive and hit Beers School Road where the adult book shop is, just down from the USAir Credit Union.  It would have continued west (today this is the location of the Port Authority Park and Ride Lot), skirting behind Rosemont Estates (the subdivision behind the car wash) and tying in with the new Expressway just beyond the cargo buildings.
Though some property was acquired, the extension and terminal bypass was never built. (2)  The need for a terminal bypass became moot in the late 1980s when construction for the airport's new Landside Terminal and direct access from the Southern Expressway (PA 60 now I-376) began.  The new highway and terminal began operation in 1992.  The concrete ghost stubs for the Beaver Valley Expressway extension would be removed with the construction of the International Drive interchange in 2003. 

By 2003, this was all that was left of the Expressway's extension ghost stubs. (Denny Pine)

Flaugherty Run Road High Speed Interchange Stubs:

The Flaugherty Run Road interchange sits not that far north of the Beaver Valley Expressway Extension stub.  The diamond interchange was opened in the early 1970s when the Beaver Valley Expressway made its way towards the airport.  When the Southern Expressway was built in the early 1990s, a half-interchange connection between the two freeways was built just to the north.  This connection did not allow northbound traffic along the BVE to make a "U-Turn" so to speak onto the Southern Expressway or northbound PA 60 traffic to exit for access to the cargo and maintenance areas along the Beaver Valley.  Initial plans were to built a high-speed freeway to freeway access utilizing some of the ramps from the Flaugherty Run Road interchange. In addition, Flaughery Run Road traffic would have access to/from the Southern Expressway.

At the time, it was determined that the high-speed connection was not necessary and that the access ramps to/from Flaugherty Run Road would serve as the connection between the two freeways.  Grading work and some of the ramps were built along with a wide median that would allow for the construction of the bridges that would carry the higher speed ramps.  At this time, there are no plans to build the high-speed ramps as it is not viewed as necessary.

Former California State Route 1 over Old Pedro Mountain Road

California State Route 1 in western San Mateo County traverses the Montara Mountain spur of the Santa Cruz Mountains.  In modern times California State Route 1 passes through Montara Mountain via the Tom Lantos Tunnels and the highway is traditionally associated with Devils Slide.  Although Devils Slide carries an infamous legacy due it being prone landslides it pales in comparison to the alignment California State Route 1 carried prior to November 1937 over Old Pedro Mountain Road.   Old Pedro Mountain Road opened to traffic in 1915 and is considered one of the first major asphalted highways in California.  Old Pedro Mountain Road clambers over a grade from Montara towards Pacifica via the 922 foot high Saddle Pass.  Pictured above an overlook of Old Pedro Mountain Road facing southward towards Montara as it appears today.  Pictured below it the same view during June 1937 when it was part of the original alignment of California State Route 1.  Today Old Pedro Mountain sits abandoned a

Former US Route 101 and California State Route 1 in San Luis Obispo

Originally US Route 101 upon descending Cuesta Pass southbound entered the City of San Luis Obispo via Monterey Street.  From Monterey Street US Route 101 utilized Santa Rosa Street and Higuera Street southbound through downtown San Luis Obispo.  Upon departing downtown San Luis Obispo US Route 101 would have stayed on Higuera Street southward towards Pismo Beach and Arroyo Grande.  Notably; beginning in 1934 US Route 101 picked up California State Route 1 at the intersection of Monterey Street/Santa Rosa Street where the two would multiplex to Pismo Beach.  Pictured below is the 1 935 Division of Highways Map of San Luis Obispo County depicting the original alignments of US Route 101 and California State Route 1 in the City of San Luis Obispo.   Part 1; the history of US Route 1 and California State Route 1 in San Luis Obispo San Luis Obispo lies at the bottom of the Cuesta Pass (also known as the Cuesta Grade) which has made it favored corridor of travel for centuries.  Cuesta Pass

California State Route 232

This past month I drove the entirety of California State Route 232 in Ventura County. CA 232 is an approximately 4 miles State Highway aligned on Vineland Avenye which begins near Saticoy at CA 118 and traverses southwest to US Route 101 in Oxnard.  The alignment of CA 232 was first adopted into the State Highway System in 1933 as Legislative Route Number 154 according to CAhighways.org. CAhighways.org on LRN 154 As originally defined LRN 154 was aligned from LRN 9 (future CA 118) southwest to LRN 2/US 101 in El Rio.  This configuration of LRN 154 between CA 118/LRN 9 and US 101/LRN 2 can be seen on the 1935 California Division of Highways Map of Ventura County. 1935 Ventura County Highway Map According to CAhighways.org the route of LRN 154 was extended west from US 101/LRN 2 to US 101A/LRN 60 in 1951.  Unfortunately State Highway Maps do not show this extension due to it being extremely small. During the 1964 State Highway Renumbering LRN 154 was assigned CA 232.  Of n
