Pennsylvania Route 611 (PA 611) is a state highway in eastern Pennsylvania running 109.7 mi (176.5 km) from Interstate 95 (I-95) in the southern part of Philadelphia north to I-380 in Coolbaugh Township in the Pocono Mountains.

Through most of Philadelphia, PA 611 follows Broad Street, the main north-south street in Philadelphia. The route continues north through the northern suburbs of Philadelphia and serves Jenkintown, Willow Grove, and Doylestown, the latter of which it bypasses on a freeway. North of Doylestown, PA 611 heads through rural areas and runs along the west bank of the Delaware River to Easton in the Lehigh Valley. The route continues back into rural land and passes through the Delaware Water Gap, at which point it enters the Pocono Mountains region, heading northwest through Stroudsburg and Mount Pocono toward its northern terminus.

The current alignment of PA 611 is composed of several turnpikes that were built in the 19th century. What is now PA 611 was designated as part of U.S. Route 611 (US 611) in 1926, a U.S. highway that ran from Philadelphia City Hall in Philadelphia north to US 11 in Scranton. US 611 was designated along part of the Lackawanna Trail, which carried the PA 2 designation between 1924 and 1928. The location of the route's northern terminus in the Scranton region has changed numerous times.

In the 1930s, US 611 underwent two realignments along the stretch of the road connecting Easton and Stroudsburg. In 1953, US 611 was moved to a new alignment between Portland and Delaware Water Gap that crossed the Delaware River twice and ran through a section of New Jersey, with the former alignment becoming US 611 Alternate (US 611 Alt.). The alignment of the route in New Jersey and across the Delaware Water Gap back into Pennsylvania became part of I-80; US 611 was shifted back to its Pennsylvania alignment in 1965, replacing US 611 Alt.

US 611 was decommissioned in 1972 and the route was replaced with PA 611 between Philadelphia City Hall in Philadelphia and I-81E (now I-380) in Tobyhanna and PA 435 between I-81E in Gouldsboro and I-81E in Dunmore. PA 611 was moved to a freeway bypass of Doylestown in 1976. The route was extended south from Philadelphia City Hall to its present terminus at I-95 in the 1980s, replacing a section of PA 291.

PA 611 begins at an interchange with I-95 (Delaware Expressway) in the South Philadelphia section of Philadelphia in Philadelphia County, heading north on Broad Street.

U.S. Route 611
Location	Philadelphia–Scranton
Existed	1926–March 14, 1972

What is now PA 611 between Philadelphia and Willow Grove was originally built as part of the Old York Road, a road established in the 18th century to connect Philadelphia to New York City. This portion of the road was planned in 1711 to run from Philadelphia to Centre Bridge. The Old York Road would later exist as a turnpike. In 1811, the Philadelphia and Great Bend Turnpike, a private turnpike, was chartered to run between Philadelphia and Great Bend. This turnpike was built to attract settlers to rural Pennsylvania. The section through Covington Township was built as a plank road between 1819 and 1826 by John Delong under the employment of Henry Drinker. The Philadelphia and Great Bend Turnpike, which was also known as the Drinker Turnpike, was built from 1826 to 1828.

In 1823, the Willow Grove and Doylestown Turnpike Company was chartered to build a turnpike between Willow Grove and Doylestown. The turnpike between Willow Grove and Doylestown was completed in the 1830s. The Easton Road between Doylestown and Plumsteadville was improved into a turnpike in the 1840s.

Following the passage of the Sproul Road Bill in 1911, the route between Philadelphia and Scranton was designated as Legislative Route 151 between Philadelphia and Doylestown, Legislative Route 156 between Doylestown and Easton, Legislative Route 165 between Easton and Bangor, Legislative Route 166 between Bangor and Stroudsburg, and Legislative Route 168 between Stroudsburg and Scranton. In 1921, the Lackawanna Trail was built as a paved auto trail running from Easton north through Stroudsburg to Scranton and the New York border.

After being constructed, the trail was one of the best paved roads in the eastern part of the United States. The road between Philadelphia and Scranton was designated by the state in 1924 as part of the Lackawanna Trail, which continued north past Scranton to the New York state line in Great Bend. The Lackawanna Trail was numbered as PA 2. With the creation of the U.S. Highway System in 1926, US 611 was designated concurrent with PA 2 along the Lackawanna Trail between Philadelphia City Hall in Philadelphia and parent route US 11 in Scranton.

The entire length of US 611 was paved by 1926.

Pennsylvania Route 302
Location	Stroudsburg
Existed	1928–1930

Pennsylvania Route 827
Location	Martins Creek
Existed	1928–1930s

In 1928, the concurrent PA 2 designation was removed from US 611. The same year, PA 191 was designated onto Broad Street in Philadelphia between Moyamensing Avenue and Philadelphia City Hall. In 1928, PA 827 was designated onto the portion of Delaware Drive between US 611 in Martins Creek and Martins Creek Belvidere Highway; this road was paved. In addition, the section of Delaware Drive between east of Martins Creek and Mount Bethel was an unnumbered paved road. In 1928, PA 612 was designated onto unpaved Foxtown Hill Road between US 611 in Delaware Water Gap and south of Stroudsburg while PA 302 was designated onto paved Park Avenue between PA 612 and US 611 in Stroudsburg. By 1930, the portion of PA 612 along Foxtown Hill Road was paved while the PA 302 designation was removed. The northern end of US 611 was routed by 1930 to follow Drinker Street and Blakely Street in Dunmore to end at US 11 at Green Ridge Street, with US 11 having replaced US 611 along Green Ridge Street to Main Avenue in Scranton.

In the 1930s, US 611 was realigned to follow Delaware Drive between Martins Creek and Portland, replacing the entire length of PA 827. The former alignment of the route between Martins Creek and Mount Bethel via Bangor was designated as PA 712; this road is now unnumbered Main Street and Lower South Main Street between Martins Creek and Bangor and PA 512 between Bangor and Mount Bethel. US 611 and PA 612 switched alignments between Delaware Water Gap and Stroudsburg in the 1930s, with US 611 realigned to follow Foxtown Hill Road and Park Avenue between Delaware Water Gap and Stroudsburg and PA 612 designated to follow the former alignment of US 611 between Delaware Water Gap and Stroudsburg via East Stroudsburg along Broad Street, Brown Street, Prospect Street, Ridgeway Street, Bridge Street, and Main Street. By 1940, US 611 was extended north along US 11 to follow Green Ridge Street, Main Avenue, and Market Street to end at US 6 at Keyser Avenue in Scranton. In the 1930s, US 611 was widened into a multilane road across the Neshaminy Creek, between south of Doylestown and Plumsteadville, between US 46 in Portland and Slateford, between Delaware Water Gap and south of Stroudsburg, from a point north of the PA 507 intersection north to the newly-constructed PA 307 in southern Lackawanna County, and between south of Dunmore and Scranton. During the 1940s, US 611 was upgraded to a multilane road between Philadelphia and south of Doylestown, between south of Stroudsburg and north of the PA 507 intersection, and along a short stretch to the north of PA 348 in Lackawanna County. By 1950, US 611 was realigned to bypass Pipersville to the west, with the former alignment becoming Old Easton Road.

The route was also shifted west to a new alignment between north of PA 113 and north of Ottsville, with the former alignment becoming Durham Road. US 611 was extended further north along US 11 to end at US 6 at the northern edge of Scranton in the 1950s. In the 1950s, PA 291 replaced the PA 191 designation along Broad Street between Moyamensing Avenue and US 611 at Philadelphia City Hall. In the 1950s, US 611 was upgraded to a divided highway between Philadelphia and PA 63 in Willow Grove, between Scotrun and PA 196 in Mount Pocono, and along a short stretch south of PA 490 (now PA 423) in Tobyhanna. The section of US 611 between PA 590 in Elmhurst and Dunmore was improved to a divided highway in 1958, with the section of the route leading into Dunmore moved to a new alignment.

In 1953, US 611 was realigned between Portland and Delaware Water Gap to cross the Delaware River on the Portland–Columbia Toll Bridge into New Jersey, where it continued along a new multilane road on the east bank of the Delaware River before crossing back into Pennsylvania on the Delaware Water Gap Toll Bridge. The former alignment of the route in Pennsylvania between Portland and Delaware Water Gap was designated as US 611 Alt. By 1960, the alignment of US 611 across the Delaware Water Gap Toll Bridge became part of I-80.

On December 1, 1962, the American Association of State Highway Officials (AASHO) approved realigning US 611 to follow I-80 between the northern terminus of US 611 Alt. in Delaware Water Gap and Scotrun. In 1963, the Pennsylvania Department of Highways (PDH) recommended replacing US 611 Alt. with US 611, with the US 611 designation to be removed from I-80. On December 5, 1964, approval was given by AASHO to realign US 611 to follow the alignment of US 611 Alt. between Portland and Stroudsburg and the former surface alignment between Stroudsburg and Scotrun instead of following I-80 and crossing the Delaware River twice to run through New Jersey. Signs reflecting the realignment were to be changed by April 1, 1965. US 611 was upgraded to a divided highway between County Line Road north of Horsham and Doylestown in the 1960s. The section of US 611 between Tobyhanna and Gouldsboro was upgraded to a freeway and became part of I-81E (now I-380) in the 1960s.

On December 5, 1964, AASHO approved eliminating the section of US 611 between I-81 in Dunmore and US 6/US 11 in Scranton, cutting back the northern terminus of US 611 to the interchange with I-81 in Dunmore. US 611 was rerouted to follow a section of the I-81E freeway in Dunmore to end at I-81.

On December 3, 1971, AASHO approved the elimination of the US 611 designation. On March 14, 1972, US 611 was decommissioned and replaced with PA 611 between Philadelphia and I-81E in Tobyhanna and PA 435 between I-81E in Gouldsboro and I-81E in Dunmore. Signs were changed by April of that year.

The southern terminus of PA 611 was located at PA 3 and PA 291 at Philadelphia City Hall. By 1989, PA 611 was extended south along Broad Street from Philadelphia City Hall to I-95, replacing PA 291 between Moyamensing Avenue and Philadelphia City Hall.

In the 1950s and 1960s, plans were made for a freeway along the US 611 corridor between Philadelphia and Easton. The proposal called for extending the freeway section of PA 63 (Woodhaven Road) from Northeast Philadelphia northwest to an interchange with the Pennsylvania Turnpike (I-276) in Southampton. From here, the freeway would become the Cross County Expressway and parallel US 611, utilizing the present-day Doylestown Bypass and continuing north to the south end of the PA 33 freeway near Easton. Most of this proposed freeway was not built.

In 1970, the state awarded contracts to build a bypass for US 611 around Doylestown. The freeway bypass for PA 611 around Doylestown opened in 1976, removing the route from its former alignment that ran through Doylestown on Main Street. By 1989, PA 611 was upgraded to a divided highway between the Pennsylvania Turnpike (I-276) interchange in Willow Grove and PA 463 in Horsham.

In September 2021, the remnants of Hurricane Ida damaged an arch culvert along PA 611 in Williams Township, resulting in the closure of this portion of road. The road reopened to traffic on March 4, 2022, after repairs were made. In April 2022, heavy rains washed out a slope and retaining wall along a portion of PA 611 in the Delaware Water Gap National Recreation Area, resulting in the route being closed indefinitely between Portland and Delaware Water Gap until repairs could be completed. This section of road reopened to traffic in May 2022. On December 6, 2022, heavy rains caused a rockslide along PA 611 between Portland and Delaware Water Gap, resulting in the closure of this stretch of road indefinitely. The closure of this stretch of PA 611 impacted businesses in Delaware Water Gap, with some forced to close. The Pennsylvania Department of Transportation (PennDOT) plans to repair the road by removing loose rock from the side of Mount Minsi, after which a single lane would be reopened and long-term stabilization of the slope will begin. After the stabilization of the slope, the road will fully be reopened to traffic. Repairs were delayed until the National Park Service granted PennDOT a permit to remove rock. Construction to repair this section of road began on August 14, 2024. A single lane controlled by traffic signals reopened on November 5, 2024.

Pennsylvania Route 611 Truck
Location	Bartonsville–Tannersville
Length	5.0 mi (8.0 km)
Existed	2013–2015

Pennsylvania Route 611 Truck (PA 611 Truck) was a truck route of PA 611 that bypassed the stretch of the route between Bartonsville and Tannersville in Monroe County from 2013 to 2015. PA 611 Truck northbound started at the intersection of PA 33 and PA 611. When PA 33 interchanges with I-80, the truck route headed onto I-80 west. In Tannersville, it reached an interchange with PA 715 at exit 299 and a mile later, PA 611 Truck left I-80 at exit 298 to PA 611, coming to its northern terminus. PA 611 Truck southbound started at PA 611 and merged onto I-80 east at exit 298. It had an interchange with PA 715 at exit 299 and 3 miles later, exited I-80 onto PA 33 north. PA 611 Truck reached its southern terminus 0.13 miles (0.21 km) later at PA 611. However, the truck route was decommissioned in 2015.

U.S. Route 611 Alternate
Location	Philadelphia–Willow Grove
Existed	1946–1950s

U.S. Route 611 Alternate (US 611 Alt.) was an alternate route of US 611 between Philadelphia and Willow Grove. The route began at US 309, US 422, and US 309 Truck at the intersection of Germantown Avenue, Chew Avenue, and Mt. Airy Avenue in Philadelphia, heading northeast on Mt. Airy Avenue. The route became Easton Road as it entered Montgomery County at the Cheltenham Avenue intersection. A short distance after this, the alternate route formed a short concurrency with PA 152 near that route's intersection with PA 73.

US 611 Alt. continued northeast through Glenside and Roslyn before it reached Willow Grove, where it crossed PA 63 before ending at US 611 a short distance south of the southern terminus of PA 263. US 611 Alt. was first designated by 1946. The alternate route was decommissioned in the 1950s.

U.S. Route 611 Alternate
Location	Portland–Delaware Water Gap
Existed	1953–1965

U.S. Route 611 Alternate (US 611 Alt.) was an alternate route of US 611 that ran between Portland and Stroudsburg across the Delaware Water Gap. US 611 Alt. began at Portland in Northampton County, where US 611 crossed the Portland–Columbia Toll Bridge into New Jersey. From here, it headed north on the west bank of the Delaware River, passing through Slateford. The route traversed the Delaware Water Gap into Monroe County and continued to Delaware Water Gap, where US 611 Alt. reached its northern terminus at an intersection with US 611 at Foxtown Hill Road.

US 611 Alt. was designated in 1953 on the former alignment of US 611 when US 611 was realigned to use a new alignment across the river in New Jersey, crossing the Delaware River twice on the Portland–Columbia Toll Bridge and the Delaware Water Gap Toll Bridge. US 611 Alt. was proposed to be extended from Delaware Water Gap north along the former alignment of US 611 through Stroudsburg to Scotrun after US 611 was realigned to follow I-80. However, AASHO denied the extension of US 611 Alt. from Delaware Water Gap to Scotrun on December 1, 1962, and instead suggested that Pennsylvania resubmit the request by establishing a business route along the former alignment of US 611.

An extension of US 611 Alt. north along the former alignment of US 611 to an interchange with I-80 and US 611 west of Stroudsburg was denied by AASHO on June 18, 1963. In 1963, the PDH recommended replacing US 611 Alt. with US 611, with the US 611 designation to be removed from I-80.

On December 5, 1964, AASHO approved the elimination of the US 611 Alt. designation. US 611 Alt. was replaced by US 611 in 1965 when US 611 was rerouted out of New Jersey. I-80 had replaced the alignment of US 611 in New Jersey.
