. The highway was initially planned to connect down to I-95 in Delaware County, but, due to environmental and local opposition, this portion did not open until 1991. In 1996, the I-476 designation was affixed to the preexisting Northeast Extension of the Pennsylvania Turnpike, replacing Pennsylvania Route 9 (PA 9). This was an older four-lane pre-Interstate limited-access highway that opened in sections between 1955 and 1957. Of earlier design, its cross section was very narrow, with only between opposing lanes of traffic in places. This extended I-476 north of Plymouth Meeting to Clarks Summit (near Scranton) as a part of the Pennsylvania Turnpike system. I-476 connected to the Northeast Extension at a state-of-the-art three-level interchange. This provided direct access to both I-276 east and I-476 north, now on the Northeast Extension.

method of tolling between the Mid-County and Wyoming Valley toll plazas along with the mainline Pennsylvania Turnpike between Warrendale and Neshaminy Falls. With the ticket system, a motorist received a ticket upon entering the turnpike at an interchange and paid the fare and surrendered the ticket upon exiting. If a motorist lost the ticket, the turnpike charged the highest fare to the exit where the motorist left. Cash, credit cards, and E-ZPass were accepted at traditional toll plazas. On April 29, 2018, the turnpike commission implemented all-electronic tolling at the Keyser Avenue and Clarks Summit toll plazas. All-electronic tolling was originally scheduled to be implemented on the entire length of the Northeast Extension in the later part of 2021.

were built in 1970 but remained closed to traffic as they did not connect to any other roads. The section of I-476 between I-76 and Chemical Road opened to traffic in 1979 while the section between I-95 and MacDade Boulevard opened to traffic in August 1988. The road opened between Chemical Road and Plymouth Road in August 1991 while the final section of I-476 between MacDade Boulevard and I-76 was opened in December 1991. An agreement in 1985 led to many environmental compromises in the road's design, including a downsized four-lane design south of PA 3 (although a part of the span between exits 9 and 5 has a third lane on the southbound side), ramp meters, and scenic route status, prohibiting the erection of advertisement billboards along the entire freeway portion. The Radnor Gateway Enhancement Strategy was implemented to install largescale sculpture elements by artist William P. Reimann, most notably the stone griffin and cairn at exit 13. While the redesigned highway was largely well-received, the constriction to four lanes has led to bottleneck conditions in the area, and many communities that originally opposed the road have now called for its widening.

'' dubbed I-476 "the most costly, most bitterly opposed highway in Pennsylvania history" due to the decades of opposition it garnered. Plans to build an interchange connecting I-476 (Mid-County Expressway) to the Pennsylvania Turnpike were made; the turnpike commission approved a contract to build the interchange in March 1989. That June, a losing bidder decided to challenge the turnpike commission, saying it violated female and minority contracting rules regarding the percentage of these employees that were used for the project. Under this rule, bidders were supposed to have at least 12 percent of contracts to minority-owned companies and at least four percent to female-owned companies. The losing bidder had 12.4 percent of the contracts to minority companies and 4.2 percent to female-owned companies while the winning bidder had 6.1 percent and 3.7 percent respectively. The turnpike commission decided to rebid the contract but was sued by the original contractor. This dispute delayed the construction of the interchange. The contract was rebid in November 1989 after the

permitted it. The interchange between I-476 and the turnpike mainline was completed in November 1992; the ramps to the Northeast Extension opened a month later. An official ribbon-cutting took place on December 15, 1992. In the 2000s, the road underwent a rehabilitation project, including paving, bridge repair, and ramp maintenance of the entire length of the freeway between I-95 and the Pennsylvania Turnpike. The section between I-95 and PA 3 was repaved in 2005 while the section between PA 3 and I-76 was repaved in 2007. The section between I-76 and I-276, which was completely reconstructed, was finished in the end of 2011.

The Northeast Extension was planned to run from the mainline Pennsylvania Turnpike in Plymouth Meeting north to a temporary terminus at Scranton.

Due to the mountainous terrain it passed through, a large amount of earthwork was necessary to build the road along with the construction of large bridges. Dakelman and Schorr, p. 106. Among the bridges built was the Clarks Summit Bridge (since renamed for John J. Fitzgerald, Turnpike engineer and superintendent) over US 6/US 11, which at the time was the tallest bridge on the Pennsylvania Turnpike system at . Dakelman and Schorr, p. 107. The Northeast Extension also included the two-lane Lehigh Tunnel under Blue Mountain. The tunnel was originally going to be named for commission chair Evans but was changed when he was convicted of conspiracy to defraud the commission of $19 million (equivalent to $ in ). The roadway opened between Plymouth Meeting and the Lehigh Valley interchange near Allentown on November 23, 1955. The highway was extended north to a temporary interchange at

on December 28 of that year. Cupper, p. 31. The Northeast Extension was opened between Emerald and Wyoming Valley on April 1, 1957. The entire length of the Northeast Extension was finished on November 7, 1957, with the completion of the northernmost part between Wyoming Valley and Scranton. The part of the Northeast Extension between Scranton and the New York state line was not built as part of the Pennsylvania Turnpike system but rather the Interstate Highway System as I-81. Dakelman and Schorr, p. 108. At the northern terminus, the Northeast Extension narrowed to two lanes along the northbound offramp at Scranton to come to its northern terminus, with an abandoned short spur of the mainline heading north.

were built to connect the Northeast Extension and I-81. In 1974, the roadway was designated PA 9. When it first opened, traffic on the Northeast Extension of the Pennsylvania Turnpike was light. By the 1970s, traffic along the roadway increased with the completion of the connecting I-80 and the rising popularity of the Pocono Mountains as a vacation destination. As a result, the two-lane Lehigh Tunnel faced serious congestion. Plans were made to either bypass the tunnel or add a second tube. The turnpike commission decided it would build a second tunnel as the cost was lower than building a bypass. Cupper, p. 40. In 1988, a $37-million (equivalent to $ in ) contract was awarded to build the second tube. Cupper, p. 46. Groundbreaking for the tunnel took place on February 14, 1989, with Governor Robert P. Casey in attendance. Excavation of the new tunnel began in July of that year. Construction of the second tube utilized the

, which reduced the cost of the tunnel by $5 million to $6 million (equivalent to $ to $ in ). It was the first tunnel in the US to use this construction method. The second tube at Lehigh Tunnel opened on November 22, 1991, with Governor Casey in attendance leading a line of antique cars. Construction of the tunnel cost $45 million (equivalent to $ in ). The new tube is used for southbound traffic while the original tube carries northbound traffic. The newer tunnel is wider, higher, and brighter than the original. On February 1, 1995, the Keyser Avenue interchange near Scranton was slated to open at a cost of $22.4 million (equivalent to $ in ). Construction of this interchange also involved constructing a new mainline flat-rate toll barrier near the new interchange. On November 1, 1996, the Northeast Extension was added to the Interstate Highway System as a northern extension of I-476, replacing the PA 9 designation along the road. The addition of the second tube at the Lehigh Tunnel along with new guardrails and line striping was necessary for the toll road to become an Interstate. It was hoped that the Interstate designation would bring economic development and tourism to the areas served by the roadway. This extension resulted in I-476 surpassing the

. The tickets along the Northeast Extension of the Pennsylvania Turnpike were originally handed out by person. In 1987, machines started to replace humans in distributing tickets. In 1990, an electronic toll collection system was proposed for the Pennsylvania Turnpike, where a motorist would create an account and use an electronic device that would be read from an electronic tollbooth. The motorist would be billed later. The multi-state electronic tolling system, which was to be called E-ZPass, was planned to be implemented by 1998. The planned installation date was later pushed back to 2000. On December 2, 2000, E-ZPass debuted along the Northeast Extension of the Pennsylvania Turnpike between Mid-County and Lehigh Valley. On December 15, 2001, E-ZPass was extended to include the entire length of the Northeast Extension of the Pennsylvania Turnpike. Commercial vehicles were allowed to start using E-ZPass on December 14, 2002. On November 24, 2004, the day before

, after contract negotiations failed. This was the first strike in the history of the roadway. As this is usually one of the busiest traffic days in the US, to avoid traffic jams, tolls were waived for the rest of the day. Starting on November 25, turnpike management personnel collected flat-rate passenger tolls of $2 and commercial tolls of $15 from cash customers on the ticketed system, while E-ZPass customers were charged the lesser of the actual toll or the same flat rates. The strike ended after seven days when both sides reached an agreement on November 30, 2004. Normal toll collection resumed December 1, 2004. In 2007, the turnpike commission announced plans to widen the Northeast Extension to six lanes between Mid-County and Lansdale. The project divided this stretch of highway into two sections. Work on the southern section began in January 2008 with the replacement of two bridges over the Northeast Extension to accommodate the widened highway. Construction on the actual widening phase commenced in January 2011. Completion was originally planned in 2013; however, construction fell a year behind schedule. The southern section finished up in October 2014, while work on the northern section started in May 2014. By this point, the project scope was expanded to include the Lansdale interchange itself, the roadway to a point north of the interchange, and two new E-ZPass-only ramps at the Lansdale interchange to relieve congestion at the toll plaza. This new northbound exit ramp opened December 4, 2016, and the companion southbound onramp opened a week later. Construction along the northern section was originally planned to finish by the end of 2016 but was delayed until mid-2017. Construction was substantially completed, with all six lanes open, by August 31, 2017. Once widening was completed from Mid-County to Lansdale, a similar project began on the next segment of highway, from Lansdale to Quakertown. As done on the first project, the Lansdale–Quakertown segment was rebuilt in two sections, with a southern half started in late 2017, with widening to six lanes and full shoulders. Advance work began in early 2013 with replacement of several bridges in this area north of Lansdale, with work on the actual widening beginning in late 2017. Widening of this section was completed in late 2020. The turnpike commission has stated its intention of continuing the widening effort past Quakertown all the way north to the Lehigh Valley interchange at milepost 56, although it will take until the late 2020s to get it done. In 1990, plans were made to build an interchange at PA 903 in Carbon County. A bill authorizing construction of this interchange was signed into law by Governor Casey in July of that year. Plans for this interchange were cancelled by the turnpike commission in 1995. In 2006, plans for an interchange at PA 903 were resurrected, with the proposed interchange to be all-electronic, in that it will only accept E-ZPass. Construction on the $23-million (equivalent to $ in ) interchange began in the middle of 2008. The interchange opened to traffic on June 30, 2015. On April 28, 2016, plans were announced for a "Scranton Beltway" to use I-476 as a bypass for I-81 around the heavily congested segment through Scranton and its suburbs. The turnpike between the two I-81 interchanges carries an average of 10,000 vehicles per day vs. 70,000 on the parallel segment of I-81. This project will build two high-speed connections between I-476 and I-81: one south of Scranton in

and one north of Scranton in South Abington Township. Tolls on the connections will be paid with E-ZPass or toll by plate. Construction of this project is expected to cost $160 million.

revealed that a section of conduit fell into the path of Sexton's truck after the steel support system for the conduits, which were suspended from the apex of the tunnel arch directly over the travel lanes, failed.

Exit list

The old exit numbers (31 and upward) on the turnpike Northeast Extension were a continuation of old exit numbers 1 through 30 on the east–west turnpike. On the east–west turnpike, the interchange with I-476 was old exit 25A because it was between old exits 25 and 26 on the east–west turnpike.
