History: Signed in 1925, from Erie to Water Street on the current PA 97, US 322, PA 350, PA 970, and PA 453.

In 1928, not only was the route's eastern terminus moved to Philadelphia via the US 22, PA 653, US 322, PA 34, PA 274, US 322, and PA 3 alignments but it was under construction from Covallen to Cove and completed in 1929.  In 1929, the route was under construction from Dunncannon to Covallen and Downingtown to Alton.  Those two sections were completed the following year.

In 1932, the route was moved onto the current PA 99 alignment from Erie to Cambridge Springs.  In 1936, the route was removed from traversing Pennsylvania from northwest to the southeast and signed in Erie County in 1936 on its current alignment except in Erie where it followed the current Alternate PA 5 alignment.  Also that year, the section from US 20 to the Fairview Township line was paved.

In 1955, the route swapped alignments with Alternate PA 5 in Erie.  Work to widen and install a median from Barnes Road to Orchard Beach Road in Northeast took place in 1958.

Median installation continued in the City of Erie in 1966 from Raspberry Street to Peach Street and Ash Street to Payne Avenue.  The last segment to be reconfigured was in 1982 at the Interstate 79 interchange, where the route was widened and a median installed from the City of Erie line to Greengarden Road as part of the interchange construction.

History: In 1927, the route was signed from Beaver Falls to Erie, and then a year later the route was extended south from Beaver Falls to West Virginia.

In 1928, the route was moved to its current alignment between PA 158 and Greenville.  Originally, it traveled the current PA 158 and PA 58 alignments.  That year it was under construction from US 30 to Service Church Road and Hill Road to PA 198 and completed the following year.  In 1929, the route was under construction from Harshaville to Service, which was finished the following year.  Also that year, paving was done from Nettle Hill to Whitecottage, Gretna to current PA 50 and Shaffer Road to Shippingport.

In 1932, the section from West Virginia to Nettle Hill, Florence to US 30, and Green Garden Road to Mowry Road was paved.  In 1935, the section from Nineveh to the Washington County line was paved.  A year later, the section from the Greene County line to Old Concord was paved.

In 1958, the route was widened and a median installed between PA 551 and Koppel.

In 1963, the designation was moved from Liberty Street, Atlantic Avenue, and Washington Street in New Castle to its current alignment on Mahoning Avenue and Jefferson Street.  In 1967, the route was widened and a median installed from PA 60 to Monaca.

In 1970, the route was widened and a median installed from PA 518 to Clark.  Also that year, work to widen and install a median on the route from Clark to Transfer began. Construction was extended from Transfer to Shenango in 1971 and in 1972, work on those sections were completed.  In 1971, the route was widened and a median installed from US 62 to Highland Road.

The designation was moved to the PA 60 expressway from its current alignment between the West Middlesex interchange and the end of the Beaver Valley Expressway in 1970.  Moved back in 1978 and eliminating the Business PA 18 designation through West Middlesex.

In October 2001, work began to widen the highway to five-lanes in Hermitage City.  This project finished in November 2002.

For years, Geneva College in Beaver Falls has lobbied PennDOT to rectify a dangerous S-curve near the campus.  Aside from safety, the route cut into part of the campus which prevented expansion.  In Fall 2006, PennDOT began work to realign PA 18 which was completed in November 2007.

History: Signed in 1928.  In 1929, the route was under construction from Ryerson to Hopewell-Yorkshire Road, and completed the following year as well as paving from the West Virginia state line to Ryerson.

In 1932, the route was paved from Coal Lick Road to Baileys Crossroads, Crucible Road to Jacobs Ferry, and from East Riverside to Hibbs.

In 1946, the route was changed to follow the current alignment between Paisley and Uniontown.  Prior to that, it went northeast from Carmichaels via Arensburg Road, Penncraft Road, Millsboro Road, New Salem Road, Herbert Road, and Dearth Road and then multiplexed with US 40 to end at PA 51 at Pittsburgh Street in Uniontown.

In 1953, the route was shifted from Georges Road between Baileys Crossroads and Carmichaels to its current route between Baileys Crossroads and Paisley.  Also that year, a new alignment was under construction from west of Masontown to east of McCellandtown which opened in 1954.  The highway was widened and a median installed from east of Paisley, Masontown and Leckone, and in McClellandtown in 1958.

Morrisville to Curry Home Road was opened in 1966 moving the designation off Rolling Meadows Road and Curry Home Road.  A median was installed from east of Paisley to the Monongahela River in 1967.

With PennDOT restructuring their 12-Year Transportation Program, the project to improve PA 21 in Greene and Fayette Counties will be reevaluated.

History: Signed in 1928.  In 1941, the route was moved from the current PA 23 alignment and Guthrie Road to Gulph Road between Valley Forge and King of Prussia.

In 1957, the route was moved from North Spring Road and Conshohocken State Road to Gulph Road, Springs Mill Road, Old Gulph Road, Morris Avenue, and Mill Creek Road between Valley Forge and Philadelphia.

In 1965, the western terminus was moved from Lancaster to its current location.  In 1967, it was moved from Gulph Road, Springs Mill Road, Old Gulph Road, Morris Avenue, Mill Creek Road to its current route between Valley Forge and Philadelphia.

Construction began in 1976 on the "goat path expressway."  In 1978, the expressway project was cancelled by locals not wanting all the excessive traffic.  The "goat path expressway," as it is referred to was covered by dirt.  However, there has been talk of reviving this project to accommodate growing traffic levels.  PennDOT has been studying how to improve PA 23 from US 30 to PA 772, which is where the original expressway would have been built.  However, now that the restructured 12-Year Transportation Program has been released, this is now being reevaluated.

In 1984, the eastern terminus was moved from the intersection of US 30/Girard Avenue and Belmont Avenue to the current location.  Construction began on the alignment from Walnut Street in Lancaster to US 30 and opened in 1993.  This caused the route to be moved off New Holland Pike from Walnut Street to US 30 and onto this new alignment.

History: Signed in 1928.  That same year, the route was under construction from the Bedford County line to Russelville and completed the following year.  Also in 1929, the route was paved from Clearville to the Providence Township line as well as construction beginning on the section from Riddlesburg to Stonerstown.  That part was completed in 1930.

In 1938, the section from Miller Road to Clearville was improved.

In 1940, the sections from the Fulton County line to Inglesmith and from Chapmans Run to Clearville were paved.  In 1946, the section from Millers Corners to Champmans Run was improved.

In 1955, the section from Inglesmith and Millers Corners was improved.

In 1963, the northern terminus was moved from Huntingdon to Bellefonte.  also the section from Millers Corners to Chapmans Run was paved.  In 1967, the northern terminus was moved from Huntingdon to Howard and two years later it was moved again, this time to its current location.

Construction began on the Bellefonte Bypass in 1971 and opened in 1972 as a "Super-2" expressway, a two-lane expressway built on a four-lane right-of-way.  The other two lanes would not be added until 1997.

In 1973, the route was changed from following the current PA 150 alignment to its current route north of State College to Bellefonte and Howard Street and Jacksonville Road to PA 26.  In 1974, the route through State College changed.  The northbound direction was moved to South Buckhout Street, Beaver Avenue, and High Street with the southbound direction remaining on College Avenue.

In 1989, the section between Inglesmith and Millers Corners was paved, thus completing PA 26.

History: Signed in 1927 from Pittsburgh to Kittanning.  Extended north to Brockway in 1928.  In 1928, the route was under construction from Blawnox to Cheswick, Troy Hill Road to Oakland, and Hazen to Reitz Crossing Road.  Those sections were completed the following year.  In 1929, the section from Avella to Woodrow and from Hickory to Fort Cherry Road was under construction and finished the following year.  In 1930, the section from Skyline Road to PA 18 was paved as well as in Venice.  That year the western terminus was moved from Avella to Independence.

In 1958, the highway was widened and a median installed at the interchange with the Turnpike.  In 1961, the highways southern terminus was moved from Independence to PA 8 in Etna.

In 1963, this section opened to traffic from PA 8 north to the Highland Park Bridge interchange and the following year to Blawnox.  

Also that year, the Pittsburgh Area Transportation Plan recommended upgrading PA 28 and then PA 8, to a six-lane, limited-access highway starting 2,200 feet west of the 31st Street Bridge and ending at the 40th Street Bridge.  Full interchanges would be constructed at both bridges; however, this recommendation was not carried out.  It also laid out a plan that would turn PA 28 into an expressway from Pittsburgh to Brookville, this too was not carried out.

In 1964, the highway was widened and a median installed on it between Brackenridge and the Butler County line.  In 1968, construction began on the section from Blawnox to PA 910.  The expressway was proposed from that point to the Butler County line.  Construction also began on the section from Slate Lick to near Center Hill in the same year.  In 1965, the route was moved from Courthouse Road into Kittanning to bypass the borough on its current alignment.  In 1969, construction commenced on the section from PA 910 to Exit 12 and from Exit 16 to PA 356 and the Armstrong County line.

The start of the 1970s saw the construction extend from Exit 16 all the way to a new expressway alignment for US 422, also under construction, near West Kittanning.  In 1971, construction commenced on the section from Exit 15 to Exit 16.  In 1972, the expressway opened to traffic from Blawnox to PA 910 and from Exit 15 to US 422.  However, PA 28's designation was not placed on the section from Exit 15 to Exit 16.  The following year, the expressway opened from PA 910 to Exit 12.

In 1973, the route was extended to end at US 19/PA 65 at Chateau Street via Western Avenue and East Ohio Street.  In 1975, construction commenced on the section from Exit 12 to north of Tarentum; and during the following year, the construction was extended to Exit 15.  In 1978, the PA 28 designation was routed onto the newly opened highway from Exit 11 to Exit 12 and from Exit 15 to Exit 16.  The PA 28 designation still followed Freeport Road to connect between Exit 12 and Exit 15.

In 1980, the expressway opened from Exit 12 to Exit 13 and the PA 28 designation was moved onto this section.  In 1984, the route was changed to follow Western Avenue, Allegheny Avenue, North Shore Drive, General Robinson Street, and Madison Avenue for northbound traffic, and Reedsdale Street for southbound traffic in Pittsburgh.  The final section of the Allegheny Valley Expressway between Exit 13 and Exit 15 opened in 1985.

Construction began in 1985 on a new alignment from Ninth Street to East Ohio Street near the H. J. Heinz plant as part of the I-279/I-579 completion project.  The new alignment opened but PA 28 wasn't removed from North Side streets onto the current route until 1993.  That year the southern terminus was moved from the West End Bridge to its current location.

Construction began on March 24, 2000 to finish the Kittanning Bypass from PA 66 to PA 85, and was opened to traffic on December 13, 2001.

The interchange with I-279 at the southern end of the route was always a thorn in the side of drivers since it opened in 1989.  For southbound drivers wanting to continue onto I-279 south, they had to exit onto East Ohio Street and travel through three traffic signals just like a certain "town of motels" in Bedford County.  Construction on a ramp to provide a direct connection began on March 31, 2008 which weaves over Madison Avenue and under the Veterans Memorial Bridge ramps, and connects to the existing I-279 on-ramp from East Ohio Street that drivers have always used.  The new $7.9 million ramp opened to traffic on September 25, 2008.

History: This designation has to take the award for "Most Times Decommissioned and Resigned."  From 1927 to 1928, the route was signed on the current US 422 alignment from the Ohio state line to Ebensburg and on the current US 209 alignment.  In 1928, both routes were decommissioned.

Then from 1928 to 1932, the route was signed from Carlisle to Mecks Corner and then the northern terminus was moved to Juniata Bridge in 1936.  The route follwed the current PA 34, PA 274, and US 11/US 15 alignment.  From 1936 to 1941, it ran between Shippensburg and Carlisle on the current US 11 alignment.  That year it flipped alignments with US 11.

From 1936 to 1963, PA 33 was designated to what is currently PA 174 between Shippensburg and Mooredale and PA 465 to Allen Road to Carlisle.  In 1938, the section between Foltz Road and McCalisters Road was paved.

Construction on the current PA 33 alignment began in 1959 from the PA 512 interchange to the Saylorsburg interchange.  Construction finished in 1960, and with the the PA 90/PA 115 designations were moved onto the new highway.  The next section to see construction was from Saylorsburg to Interstate 80 in 1963 and finished in 1964.

A construction drought occurred from 1964 to 1969, when in that year work began on the section from US 22 to PA 512.  A year later, the section from the Belfast interchange to the PA 512 interchange opened to traffic.  The section from PA 191 to the Belfast interchange opened in 1971 and from US 22 to PA 191 finished in 1972.  With the expressway complete, PennDOT gave PA 33 its fourth home in 45 years.

One section missing was from US 22 to the rerouted Interstate 78, that now bypassed the Allentown-Bethlehem-Easton area to the south.  That problem was rectified in March 1999 when work began on the trumpet interchange at I-78.  $104.6 million project.  The main line of the three-plus mile Route 33 Extension and its new interchanges with Freemansburg Avenue and I-78 opened on January 20, 2002.

Sinkholes have always been a problem near the Stockertown area.  That problem came to light on January 24, 2004 when one developed under a support pier on a bridge carrying PA 33 north over Bushkill Creek.  The expressway was closed between PA 248 and PA 191 until temporary crossovers could be built to detour traffic.  Measures were taken to try and salvage the bridge, but in the end the ground won out as more developed in the area.  The end result was the demolition of the structure which began on February 2, 2004.  If one sinkhole was bad enough, another was discovered a mere 21 days later between the southbound bridge and where the former northbound bridge stood.  PennDOT's geotechnical engineering staff determined that it posed no problems to PA 33, and the void simply filled with fill material.  Crews noticed vertical movement in the southbound bridge on February 27, but deemed it not to be a threat.  However, on April 21, a depression formed near the northbound crossover that was built to detour traffic around the damaged bridge.  The expressway was closed for 20 minutes between 10 AM and 11 AM so crews could fill the depression with bituminous material.

Eventually the southbound bridge also had to be demolished which began on July 8.  The new northbound bridge opened on June 24, 2004 and its southbound counterpart on November 19, 2004.
