Interstate 376 (I-376) is a major
I-376 is signed east–west despite running north–south for nearly three-quarters of its length; however, it does run east–west through the majority of Allegheny County. This is because, until 2009, the route's western terminus was at
A 16-mile (26 km) stretch of the Beaver Valley Expressway, officially named the James E. Ross Highway, from exit 15 where I-376 ends its brief
Route description
Beaver Valley Expressway and Airport Parkway
I-376 begins at a cloverleaf interchange with I-80 and PA 760 located four miles (6.4 km) east of Ohio within the Glaciated Allegheny Plateau. From there, it travels in a southerly direction on the Beaver Valley Expressway, a four-lane freeway with a wide grass median. Paralleling PA 18, I-376 has its first interchange with that state highway in West Middlesex.
I-376 soon meets
I-376 continues southward, still paralleled by PA 18 and the
I-376 then passes to the east of
Approaching PIT, I-376 bends south-southwest and becomes the Southern Expressway, while the Beaver Valley Expressway diverges to the southeast along I-376 Business (I-376 Bus). I-376 circles around the southern edge of the airport, intersecting the western terminus of the Southern Beltway (PA Turnpike 576) at the main entrance to PIT before recombining with I-376 Bus and becoming the Airport Parkway, still four lanes and with a narrow median.
Parkway West
Now traveling southeast, the route comes to a
Entering the city of
After passing through the Fort Pitt Tunnel, I-376 emerges onto the four-lane double-deck Fort Pitt Bridge, crossing over the Monongahela River. There are single-lane westbound exit and eastbound entrance ramps connecting Carson Street to the freeway between the tunnel's portal and the bridge. Once across the river, the route touches down in Downtown Pittsburgh at Point State Park. An interchange at the Point connects I-376 to I-279 (Parkway North), which leads to the Fort Duquesne Bridge, as well as Liberty Avenue.
Parkway East
I-376 continues east from the Point, still carrying the partially-unsigned US 22 and US 30, following the north shore of the
Parkway East exits the city of Pittsburgh near the southeastern corner of
Tolls
The James E. Ross Highway portion of I-376 between US 422 and PA 51 uses
The tolled portion of I-376 is the most expensive portion of the Pennsylvania Turnpike system per mile, charging toll-by-plate users an average of $0.44 per mile ($0.27/km) and E-ZPass users $0.20 per mile ($0.12/km). This is in stark contrast to the mainline Turnpike, which charges less than $0.12 per mile ($0.07/km) for E-ZPass users and more than $0.17 per mile ($0.11/km) for cash users. This is due to the bonds on newer sections of the Turnpike system (such as the James E. Ross Highway,
Along with the Delaware River–Turnpike Toll Bridge (which is affected by the ongoing Pennsylvania Turnpike/Interstate 95 Interchange Project), the Beaver Valley Expressway became one of the first sections of the Pennsylvania Turnpike system to implement all-electronic tolling, which began along the Beaver Valley Expressway on April 30, 2017.[10][11] The Beaver Valley Expressway was selected as a test area so that the PTC could work out any bugs with mailing non-E-ZPass users bills with their unpaid tolls.[11]
History
The first section of what would eventually become I-376 opened June 5, 1953, from
In 1955, the
The next section that opened was in 1968 from the present-day exit 2 with PA 18 to where PA 18 intersects with the present-day PA 760 just north of I-80 and the western terminus of I-376.[18][19]
Work began on the Beaver County sections of I-376 (in between
, and PA 51 before returning to the highway. Until that section opened, the present-day exit 12A marked the southern terminus of the northern section of PA 60 as an "END 60" sign was located near the exit.In the early to mid-1980s, the entire section from downtown to Monroeville was refurbished.[21]
The next leg of the route opened to PA 108 in 1991 and to PA 51 in Chippewa on November 30, 1992, as the 16.5-mile (26.6 km) $260-million (equivalent to $507 million in 2023[14]) "missing link" between two sections of PA 60, when that route's designation was on the highway.[22] The aforementioned "END 60" sign was removed when the first leg of the middle section opened in 1991, and a "No re-entry this exit" sign has sat on the site since due to exit 12A being an indirect connection to US 422 westbound without a direct reentry ramp.
The Southern Expressway, a southern bypass of PIT, opened on September 9, 1992, and is the newest portion of I-376.[23][24]
The PTC retrofitted E-ZPass lanes on the tolled section of I-376 in 2006 at both the two mainline toll plazas as well as the exits that collect tolls.[25]
A bridge crossing I-376 from Oakland to Greenfield, the Greenfield Bridge, gained some national notoriety on an episode of Last Week Tonight with John Oliver concerning infrastructure. The state could not immediately afford to replace the crumbling bridge, so instead a cover was built under the bridge to protect the vehicles on I-376. The Greenfield Bridge was finally demolished in December 2015, and a replacement was built over the following two years, officially opening on October 14, 2017.[26]
Route designations prior to 2009
From PA 60 to I-376's eastern terminus, I-376 has had the US 22 and US 30 designations for its entire history (US 30 exiting at Wilkinsburg). Until 1961, it also carried the
From 1959 to 1964, I-70 occupied the highway east of
In 1970, I-79 swapped positions with I-279, necessitating that I-76 be extended to I-79. With commencement on the Beaver Valley Expressway in 1971, PA 60 was extended to its future northern terminus in Chippewa. Finally, on October 2, 1972, after I-76 west of Monroeville moved to the Pennsylvania Turnpike and replaced I-80S, the western part of the highway took the I-279 designation while the section from Pittsburgh east to Monroeville would become the first section with the I-376 designation.[1] When I-376 was extended onto the Parkway West in 2009, I-279 was truncated to its current southern terminus at the former western terminus of I-376.[29]
PA 18 Business was decommissioned in 1978 when PA 18 returned to its former alignment (where it has remained to this day) and PA 60 was extended all the way to Hermitage.[30][31]

On November 30, 1992, the 16.2-mile (26.1 km) gap in Beaver County was completed with a toll highway.[32]
When the Beaver Valley Expressway started opening in 1991, it would receive the "PA Toll 60" designation, because it was operated by the
2009 extensions
As part of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users in 2005, Congress had designated an expansion of I-376 past I-79 and along present day US 22/US 30 and PA 60 through Pittsburgh International Airport and north to I-80 near Sharon. This was done because the airport was one of the few major airports in the US without direct access to an Interstate Highway.[3]
This routing required some major infrastructure work on
The designation of I-279 from Downtown west through the Fort Pitt Tunnel to I-79 was officially dropped and replaced by that of I-376 on June 10, 2009.[29][35] I-279 still exists between I-376 in the Golden Triangle and I-79 in Franklin Park. On November 6, 2009, officials announced the initial transition was complete.[34]
On January 21, 2010, the remainder of the route except for the Beaver Valley Expressway started receiving the I-376 signs. The stretch of PA 60 from I-80 in Shenango Township of Mercer County north past PA 18 (where the freeway terminates and the highway reverts to being a two-lane arterial) to the former northern terminus of PA 60 in Sharon became PA 760.[36]
On August 1, 2010, signage along PA Turnpike 60 was officially changed to I-376,
Despite PennDOT giving motorists over four years of advance notice on the I-376 extension, some local drivers were confused after the transition was complete, thinking that the I-376 extension was going to be an all-new highway instead of a renaming of PA 60.[5]
As part of the ongoing upgrades to I-376 to bring the legacy portion of the former PA 60 up to Interstate standards, the interchange with PA 318 at exit 1C was upgraded to a full service interchange in October 2014. Previously, the exit only had a westbound entrance and eastbound exit, mainly to serve as access to I-80 to West Middlesex residents. It marked the third partial interchange on the legacy PA 60/Parkway West to be upgraded to a full-service interchange in a decade, after I-79 at exit 64A and access to US 30 at exit 52 were upgraded from partial to full-service interchanges.[39]
