The Bigelow Blvd. / Crosstown Expressway (Interstate 579) Ghost Ramp Mystery Explained

Image
By
For nearly five decades, many Pittsburgh-area motorists, when leaving the old Civic Arena or exiting off the Crosstown Expressway onto Bigelow Boulevard, have wondered what exactly the ghost ramp in the above photo was for.  Where was it to have come from?  When and why did they stop?  Will it ever be built?
For over 20 years, Rand McNally's maps of downtown Pittsburgh included a full connection between the Crosstown Expressway and Bigelow Boulevard.
The original plans for the Crosstown Expressway included a full interchange with Bigelow Boulevard.  However, these plans never came to fruition.  The only ramps that were built were from I-579 North onto Bigelow and from Bigelow Boulevard/PA 380 West to I-579 South.  The above ramp was to have come from I-579 South and depending on what older map of Pittsburgh you have over or under the existing roadway, and on to Bigelow/PA 380 East.  It never came to be, and now the HOV ramp to what was once the Civic Arena has basically eliminated the need for completing this interchange.



The two photos above show the retaining wall with the ghost ramp and how it would have connected to Bigelow.  The below photo shows exactly how narrow the off-ramp would have been.

There are two of different theories on why the full interchange was never built.  One is that the ramps would have resulted in the old Pennsylvania Railroad Station, Penn Station, being torn down and that local preservation groups fought to keep it standing.  However, outside of this video discussing the Bigelow ghost ramps, I have never heard of that.  It is correct that the completion of I-579 and the construction of the Veterans Bridge carrying the Interstate over the Allegheny River did impact the former Pennsylvania Railroad freight building; however, the highway's construction had no impact on the former rail station.  The other reason mentioned is that funding for the completion of the Crosstown Expressway, Interstate 579, required some type of mass transit/high occupancy vehicle requirement.  The I-279/579 HOV lanes were the result and because of this, the additional ramps were taken out.  It is most likely the combination of the two - the addition of the HOV lanes - and the impact on the freight warehouse - that caused the full Bigelow Boulevard interchange to be shelved.

The final three photos show how far along construction on this ramp went - and in even photos taken in 2001 - how the long abandoned ramp had been overgrown with grass, brush, and trees.




In addition, there were once plans to have an additional interchange along Interstate 579 connecting the Crosstown Expressway with Fort Duquesne Boulevard.  If you have any information on the overall plans and demise of the Bigelow or Ft. Duquesne Blvd. ramps and interchanges, please leave a comment or drop me an e-mail.

I think the requirement for the HOV lane basically killed it. Here is the theory video I did a few years back

Old US Route 60/70 through Hell (Chuckwall Valley Road and Ragsdale Road)

By
Back in 2016 I explored some of the derelict roadways of the Sonoran Desert of Riverside County which were part of US Route 60/70; Chuckwalla Valley Road and Ragsdale Road. US 60 and US 70 were not part of the original run of US Routes in California.  According to USends.com US 60 was extended into California by 1932.  US 60 doesn't appear on the California State Highway Map until the 1934 edition. USends.com on US 60 endpoints 1934 State Highway Map Conversely US 70 was extended into California by 1934, it first appears on the 1936 State Highway Map. USends.com on US 70 endpoints 1936 State Highway Map When US 60 and US 70 were extended into California they both utilized what was Legislative Route Number 64 from the Arizona State Line west to Coachella Valley.  LRN 64 was part of the 1919 Third State Highway Bond Act routes.  The original definition of LRN 64 routed between Mecca in Blythe and wasn't extended to the Arizona State Line until 1931 acc...

Trimmer Springs Road (Fresno County)

Trimmer Springs Road is an approximately forty-mile rural highway located in Fresno County.  The corridor begins near in California State Route 180 in Centerville and extends to Blackrock Road at the Kings River in the Sierra Nevada range near the Pacific Gas & Electric Company town of Balch Camp. The roadway is named after the former Trimmer Springs Resort and was originally constructed to facilitate access to the Sanger Log Flume.  Trimmer Springs Road was heavily modified and elongated after construction of Pine Flat Dam broke ground in 1947.   Part 1; the history of Trimmer Springs Road Much of the original alignment of Trimmer Springs Road was constructed to facilitate access to the Sanger Log Flume.   The  Kings River Lumber Company  had been established in 1888 in the form of a 30,000-acre purchase of forest lands in Converse Basin.  This purchase lied immediately west of Grant Grove and came to be known as "Millwood."  The co...

When was Ventura Avenue east of downtown Fresno renamed to Kings Canyon Road? (California State Route 180)

By
California State Route 180 was one of the original Sign State Routes designated in August 1934.  The highway east of Fresno originally utilized what was Ventura Avenue and Dunlap Road to reach what was then General Grant National Park.  By late year 1939 the highway was extended through the Kings River Canyon to Cedar Grove.   In 1940 General Grant National Park would be expanded and rebranded as Kings Canyon National Park.  The Kings Canyon Road designation first appeared in publications circa 1941 when the California State Route 180 bypass of Dunlap was completed.  Kings Canyon Road ultimately would replace the designation of Dunlap Road from Dunlap to Centerville and Ventura Avenue west to 1st Street in Fresno.   The Kings Canyon Road would remain largely intact until March 2023 when the Fresno Council designated Cesar Chavez Boulevard.  Cesar Chavez Boulevard was designated over a ten-mile corridor over what was Kings Canyon Road, remaini...
