Painted blue after its 2010 reconstruction the Schuylkill Expressway Bridge carries more than just traffic. This bridge carries history. It carries stories. Let’s delve into the tale of the Schuylkill Expressway Bridge.
This vital structure built in 1956 by the Pennsylvania Department of Transportation spans the Schuylkill River. It links West Philadelphia and Grays Ferry in South Philadelphia. It’s officially named the Schuylkill Expressway Bridge.
Imagine the Schuylkill Expressway Bridge in 1932. The Regional Planning Federation envisioned a parkway system. It was similar to Robert Moses’ projects in New York. Stone-arch bridges and natural vegetation would line the route. The Valley Forge Parkway was a key part. It would connect Fairmount Park and Valley Forge National Historic Park. A “power broker” was missing. The parkway system never materialized. Officials preserved the plan for a cars-only artery until the mid-1940s.
By 1947, the Philadelphia City Planning Commission approved expressway plans. Borrowing from the Valley Forge Parkway, the Schuylkill Expressway would have controlled access. Unlike the parkway, trucks and buses were allowed.
Consider two design engineers. Michael Rapuano valued safety and aesthetics. Bill Allen prioritized streamlined efficiency. Rapuano used the Valley Forge Parkway design. He navigated steep slopes and a historic railroad tunnel. Allen squeezed lanes wherever possible. He moved the riverbank eight feet near 30th Street Station. This created just two feet of clearance.
Allen said most people don’t notice the clearance. It’s dark and they’re moving fast.
Initially, the Schuylkill Expressway was to extend 20 miles. It ran from the Pennsylvania Turnpike to the University Avenue bridge. Later, it extended five miles to the proposed Walt Whitman Bridge. The expressway featured four lanes and wide shoulders where possible.
The first section opened in 1954. Traffic jams quickly formed on City Line Avenue. The New York Times even reported it. Construction continued through Philadelphia. Financial issues and war-deferred projects caused delays. The 1956 Federal Highway Act eased the situation.
Mayor Richardson Dilworth linked himself to the Schuylkill Expressway. He later called it his “worst mistake”. He lamented its impact on Fairmount Park.
In the early to mid-1950s, costs were split between state and federal governments. The Schuylkill Expressway officially became part of the Interstate system in 1956. It received I-76 designation in 1973. Despite this designation, it didn’t always meet Interstate standards.
By 1960, traffic volume approached 70,000 vehicles per day. Attempts to add capacity included the Manayunk Expressway. This proposal was shelved. Another plan to widen the Schuylkill Expressway to eight lanes also failed. A smaller widening project was completed in 1972.
In 1969, the Pennsylvania Department of Highways began a second operational study. It cited difficult riverfront topography. Restrictions were caused by the Schuylkill River.
In the mid-to-late 1970s, community opposition and the oil crises killed expressway plans. The Schuylkill Expressway deteriorated. A complete overhaul was needed.
Reconstruction began in 1985. It introduced new pavement and concrete barriers. The Schuylkill-Vine Street interchange had design flaws. Lightweight concrete and steel beams addressed the sinking issue.
The “Schuylkill squeeze” ended in 1989. Construction crews soon returned. They resurfaced the road from 1996. Recent projects include variable message signs.
The Schuylkill Expressway carries significant traffic. It carries about 95,000 vehicles per day in Montgomery County. The number rises to 135,000 near Center City Philadelphia.
In the late 1990s, the Schuylkill Expressway was considered for national landmark status. It was not included due to alterations and its reactionary nature. Today, the Schuylkill Expressway Bridge stands as a testament to Philadelphia’s evolution. It shows the city’s ongoing effort to balance progress and preservation.
