The Many Failed Plans of Pittsburgh's Wabash Bridge and Tunnel

The December 27, 2004 opening of the Wabash Tunnel ended over 70 years of proposals and speculation for the use of the over 100 year old facility.  The tunnel, which is now a reversible roadway that is an alternative route for rush hour traffic, saw many failed plans during the 20th Century.  These plans included options for mass transit, converted and new bridges for vehicles, and other forms of transportation.

Brief History:
Constructed in 1902-04, the Wabash Bridge and Tunnel was planned and financed by rail mogul, Jay Gould.  Gould began his "Battle of the Wabash" with the established railroads of the city in 1890.  He would finally emerge victorious, but during that struggle, Gould would see many setbacks that would eventually result in the railroad's bankruptcy in 1908.  On October 19, 1903, when the two ends of the bridge were to be joined together over the Monongahela River, the 109' bridge collapsed; killing ten men.  Construction would resume four days later (1); however, the project was still hampered by strikes, riots, landslides, and floods. (2)  The railway, named the Wabash-Pittsburg Terminal Railroad, began operations in July 1904 but would only last for four years.
 
The former Wabash line and properties were purchased by the Pittsburgh & West Virginia Railroad in 1917.  However, disasters would continue to wreak havoc on the new owners.  In November 1925, a landslide would block the tunnel's north portal and cause major damage to the trestle that connected the tunnel to the bridge.  The auto era would see the end of passenger service to the line in 1931.  Freight service would continue until 1946, when a series of fires would damage and destroy the downtown terminal and many parts of the rail yard.  The bridge would be demolished two years later with much of the steel sent upriver to be used in construction of the Dravosburg Bridge.  The demolition left an unused 3,350 foot tunnel and two stone bridge piers that sit to this day on both shores of the Monongahela.
 
1930's Urban Highway Plans:
Plans of new uses for the bridge and tunnel began in 1931.  Although the two facilities were still carrying rail traffic, Allegheny County decided to purchase the tunnel for $3,000,000.  The reason: To create another access point into downtown from the South Hills.  The Liberty Bridge and Tunnels, which opened three years earlier, were wildly successful and already exceeding traffic expectations. (1)  The plan was to convert the tunnel, bridge, and elevated track downtown into an urban highway. This highway would begin with an interchange with Saw Mill Run Boulevard, run through the tunnel and across the bridge, finally running over the elevated track to Duquesne Way. (3)

The plan would be blocked in November 1931 by a grand jury that ruled the plan - specifically the bridge and tunnel - as inadequate for vehicular traffic, that the County misrepresented the project's true cost, and that the commissioners did not get approval from the planning commission. (1)  The suit that resulted in the termination of the $3 million purchase was filed by Newton and Emma Hopkins.  They argued that the 21 foot wide tunnel would be a "...hazard in the event an automobile should stall or be wrecked." (4)  This would be a similar concern and reason why the tunnel only carries one lane today.  The County's 1931 proposal would have aprons built onto the bridge so it could handle four lanes of traffic; however, no plans were made to twin the tunnel.  (4)
 
The 1931 failure would not stop additional attempts for the urban highway during the decade.  Urged again one year later by downtown businessmen, the County in 1933 hired Ole Singsted to study the 1931 plan.  The $5,000 study by Singsted endorsed the plan with a suggestion to build a second tunnel to add two more lanes. (1)   The County tried again, via the New Deal Administration, for $3 million in 1934, but the request was turned down.(1)  1936 saw the last attempt to convert the bridge to a highway; however, it never came to pass.
 
Skybus:
It wasn't until the mid-1960s that the next chapter in the Wabash Tunnel saga would begin.  The newly formed Port Authority of Allegheny County along with the Westinghouse Corporation began to demonstrate 'Skybus', a fully automated transit system, at the County Fairgrounds in South Park.  By 1969, Skybus became a pivotal piece of the agency's Early Action Transit Plan.  The line would use the tunnel and cross into downtown via a new bridge.  The proposal received strong support from the county.   However, Pittsburgh Mayor Pete Flaherty, who won election to the mayor's office in 1968, would begin his battle against the plan.  Although the system had yet to be approved, PAT moved forward and acquired the tunnel and spent $6 million on converting the tunnel for Skybus in 1971. (1)  After a lengthy and well publicized trial, PAT would see the public and politicians turn against the project.  Skybus would officially be dead by the mid-1970s.

A Solution to a Traffic Nightmare?
After the death of Skybus, the Wabash would sit empty.  The Port Authority would use it to store buses until vandals damaged over 80 buses in 1980. (5) In 1986, the City of Pittsburgh looked at converting the tunnel back to autos and creating a connection from Saw Mill Run Boulevard to Station Square. (6) 1992 saw the beginning of a decade long process that would result in the tunnel being converted for auto usage.  With the closure of the Ft. Pitt Bridge and Tunnels for reconstruction looming, PennDOT and officials from the City of Pittsburgh began to seriously look at the tunnel as an alternative for traffic when the bridge was closed.  In March 1992, the Highway Bridge Capital Budget was amended to include a $35 million allocation for construction of a new bridge over the Monongahela River that would use the former Wabash facilities. (7)  

One of the four Wabash Bridge proposals that were being considered by The Port Authority of Allegheny County.
Consensus was made that the new Wabash Bridge and Tunnel would be an HOV facility.  In 1994, the Port Authority began a $3.2 million project that would convert the tunnel from the never used Skybus configuration to auto usage. (5) For the next ten years, debate, revisions, postponements, and cutbacks would change the ultimate outcome.  Throughout the 1990's, arguments over cost, design of ramps along with concerns voiced by downtown businessmen - led by Steve "Froggy" Morris - would ultimately scrap plans for a new bridge.  Meanwhile, the complete rehabilitation of the Ft. Pitt Bridge and Tunnel would be delayed and ultimately completed in 2003.

The West Busway, which would also become part of the Wabash Project, was built and completed in 2000.  The overall West Busway/Wabash Tunnel project was scaled back version as acquisition costs to connect the Busway at the Corliss Tunnel and the Wabash became too high.  Finally in 2003, construction began to connect the refurbished tunnel to Carson Street.  The tunnel opened for business on December 27, 2004. 

Or Just Another Boondoggle?

Opened as a reversible High Occupancy Vehicle facility requiring two or more passengers in each vehicle, the Wabash Tunnel fell well short of usage expectations.  It was estimated that the tunnel would see 4,500 vehicles per day by 2015.  The facility only averaged 250 per day two years after it opened and only 500 vehicles per day by 2013. (9, 10) 

The Port Authority had contracted out the operation and maintenance of the facility to an outside firm.  Originally subsidized, this was a $780,000 operating expense.(9)  Because of the low usage, the operating expense would be reduced to $200,000 by 2011. (11)  The Port Authority had considered either closing or  turning over the Wabash Tunnel to PennDOT; however, PAT would have had to reimburse the Federal Transit Administration (FTA) $20 million in grant money that was used for the project and the West Busway.

Additionally, PAT would also face penalties from the FTA if they removed the HOV requirements.  In 2013, the Port Authority was granted a temporary waiver to allow all vehicles, regardless of the number of occupants, to use the Wabash Tunnel as the result of major construction along West Carson Street.  This waiver would last until 2016 when PAT was granted an additional one year waiver from the FTA because of work being done on the Liberty Bridge.  The Wabash Tunnel facility was considered as an alternative relief route for traffic impacted by those projects.  Finally, in February 2017, the Federal Transit Administration granted a permanent waiver for the Wabash Tunnel allowing all passenger vehicles to use the facility regardless of the number of occupants.

    History of the Big Oak Flat Road (Yosemite National Park)

    This week I hiked much of what was the original alignment of the Big Oak Flat Road which is located to the north of the modern roadway.  Unlike the original alignment of the Wawona Road the Old Big Oak Flat Road is surprisingly intact.


    The complete history of the Big Oak Flat Road including the original alignment can be found on a 2002 report from the U.S. Department of Interior on the Old Big Oak Flat Road.

    U.S. Department of the Interior on the Old Big Oak Flat Road

    The Big Oak Flat Road began construction east from the mining community of Big Oak Flat in towards Yosemite Valley in 1869.  The Big Oak Flat Road was constructed by the Chinese Camp and Yosemite Turnpike Company which had secured the franchise rights for a toll road to the Yosemite Grant (the designation prior to Yosemite National Park).  By the summer of 1871 the Big Oak Flat Road reached the northern cliffs above Yosemite Valley which is when the Chinese Camp and Yosemite Turnpike Company ran out of funding.  After the…

    The Tioga Pass Road

    Last Summer the Tioga Pass Road over the Sierra Nevada Mountains in Yosemite National Park opened late due to the heavy snow pack from the previous winter.  Approaching the start of July the Park Service finally had cleared the road to Tioga Pass.  That being the case I headed up shortly after the 4th of July holiday during a lull in the tourist season.


    The Tioga Pass Road runs from the Big Oak Flat Road at Crane Flat east to US Route 395 ("US 395").  The Tioga Pass Road is largely within the boundary of Yosemite National Park but is maintained by Caltrans as California State Route 120 ("CA 120") east of the Tioga Pass entry station to US 395.  The National Park Service maintained portion of the Tioga Pass Road serve as a implied connection between the two segments of CA 120.  The Tioga Pass Road is the highway mountain pass in California reaching Tioga Pass at 9,945 feet above sea level.

    Horseshoe Meadows Road; former California State Route 190 and the legacy of the Lone Pine-Porterville HIgh Sierra Road

    This summer I had an opportunity to drive one of the lesser known great roads of California; Horseshoe Meadows Road from Whitney Portal Road westward into Horseshoe Meadows of the Eastern Sierra Nevada Mountains.  Aside from being massive climb into the Eastern Sierra Nevada Mountains the path of Horseshoe Meadows Road was once part of California State Route 190 and was intended to be part of a Trans-Sierra Highway known as the Lone Pine-Porterville High Sierra Road.


    Horseshoe Meadows Road is located west of Lone Pine of Inyo County and is 19.7 miles in length.  Horseshoe Meadows Road begins at an approximate elevation of 4,500 feet above sea level at Whitney Portal Road in the Alabama Hills and ends at an elevation of 10,072 feet above sea level in Horseshoe Meadows.  Horseshoe Meadows Road is the second highest paved road in California only behind Rock Creek Road near Tom's Place.  Pjammcycling rates Horseshoe Meadows Road with an average gradient of 6.2% and lists it as th…
