Pennsylvania Route 222

Highway in Pennsylvania

Pennsylvania Route 222 (PA 222) is a 4.482 mile (7 km) long state highway located in Allentown and its surrounding suburbs in the Lehigh Valley region in eastern Pennsylvania. Most of the route runs along Hamilton Boulevard. In Center City Allentown, the route is aligned along West Hamilton, West Linden, and West Walnut Streets. The southern terminus of the route is at Interstate 78 (I 78) and PA 309 in Dorneyville, where the roadway changes designation from PA 222 to U. S. Route 222 (US 222). The northern terminus is PA 145 in Allentown. Since the city's founding in the 18th century, Hamilton Street was among the first streets constructed in the city and served as the main street in Center City Allentown. Hamilton Street and Hamilton Boulevard became part of the William Penn Highway in 1916, PA 3 in 1924, and US 22 in 1926. In 1931, US 22 was routed to a new alignment to the north, and Hamilton Boulevard and Hamilton Street west of 15th Street became a part of US 222. In the 1950s, US 222 was rerouted to bypass Allentown, leaving Hamilton Boulevard and Hamilton Street through the city unnumbered. In 1984, the Pennsylvania Department of Transportation (PennDOT) proposed extending US 222 from I 78/PA 309 to Center City Allentown, where it would end at PA 145. The American Association of State Highway and Transportation Officials (AASHTO) rejected extending US 222 into Allentown, and PA 222 was instead designated to run between I 78/PA 309 and US 222 and PA 145 in 1991.

PA 222 begins at an interchange with I 78/PA 309 in Dorneyville in South Whitehall Township in Lehigh County, which is in the Lehigh Valley, where the road continues southwest as US 222 towards Reading. From this interchange, PA 222 heads northeast on four lane divided Hamilton Boulevard. The route comes to an intersection with Lincoln Avenue that has a southbound jughandle; Lincoln Avenue provides access to the main entrance of the Dorney Park & Wildwater Kingdom amusement park. PA 222 passes between Dorney Park & Wildwater Kingdom to the north and businesses to the south. The southbound direction comes to a right in/right out with the exit from Dorney Park & Wildwater Kingdom along with the bus entrance to the amusement park. After passing the amusement park, the route splits into two carriageways, with PA 222 north remaining on Hamilton Boulevard and PA 222 south following the newer Hamilton Boulevard Bypass to the north; at the split, there is a pair of median U turn ramps. To the east, the road intersects Cedar Crest Boulevard, a major north–south arterial in the Lehigh Valley area. The Da Vinci Science Center is located at the northeast corner of PA 222 southbound and Cedar Crest Boulevard on the campus of Cedar Crest College. Northeast of Cedar Crest Boulevard, the two carriageways merge onto Hamilton Boulevard, with a U turn ramp from the northbound direction to the southbound direction at the merge, as it passes to the south of Cedar Crest College. At this point, PA 222 leaves South Whitehall Township for Allentown. The route becomes a four lane undivided road and passes through residential areas. At the intersection with Ott Street, PA 222 curves east onto Hamilton Street and runs along the southern edge of Cedar Creek Park, where it intersects 24th Street. The road continues east through residential and commercial areas, narrowing to three lanes with two northbound lanes and one southbound lane at the 20th Street intersection. The route passes to the north of St. Luke's Hospital–Allentown Campus between 18th and 17th streets and comes to an intersection with 15th Street. When the Sproul Road Bill's adoption on May 31, 1911, the state began maintenance over state highways. One of those highways was Legislative Route 157, the modern Hamilton Boulevard section of PA 222, west of Allentown. Another state highway was Legislative Route 159, aligned east of Allentown to downtown Bethlehem along Hanover Avenue and Broad Street. No routes had a designation within Allentown. In 1916, the William Penn Highway was organized as an alternative to the Lincoln Highway. The roadway traversed Center City Allentown via Hamilton Street and Hamilton Boulevard. The Pennsylvania Department of Highways gave the road the PA 3 numbering in 1924 and when the United States Highway System was formed, US 22 became part of it. The William Penn Highway served New York City; the road became problematic for motorists in Lebanon along the current US 422; Reading via current US 422 and US 222; and Allentown on Hamilton Street. PA 43 was aligned as a bypass, north of the Pennsylvania Dutch Country, between Allentown and Harrisburg. On June 8, 1931, the American Association of State Highway Officials came to a resolution to the traffic problem, by replacing the PA 43 corridor with US 22 and the William Penn Highway name to match. US 222 replaced the former US 22 alignment from Reading to Allentown. Hamilton Street was numbered as US 222, west of Center City Allentown, where it turned north onto 15th Street. This portion of US 222 was seven blocks long which ended at Tilghman Street (then US 22). Signs were changed to reflect the new designations on May 31, 1932, with the new route designations officially in place on June 1, 1932. In the late 1950s, US 222 was realigned to a newly constructed bypass carrying US 309 and PA 29, west of Allentown. From the south, US 222 left Hamilton Boulevard and turned north onto the freeway. US 222 terminated at an interchange with US 22, US 309, and PA 29 in South Whitehall Township. By 1970, what was the US 309/PA 29/US 222 freeway had the PA 29 designation removed, US 309 downgraded to PA 309 and US 222 was truncated to end at its current northern terminus. By the 1980s, I 78 became part of the freeway that occupied PA 309. In 1984, PennDOT was planning to extend PA 145 and US 222. Traffic engineer Samuel D. Darrohh said that Allentown is one of few Pennsylvania cities without a traffic route going through it. After the plan was introduced, he said that motorists might be aided if US 222 is extended along Hamilton Boulevard to connect with the proposed PA 145 corridor. PennDOT originally planned the road as US 222 but AASHTO denied the extension, stating that the route "is not the shortest or best available route between major control points on the system, and therefore, does not adhere to the policies established under AASHTO's 'Purpose and Policy Statement for U. S. Numbered Highways'". In addition, the route did not meet the criteria for a business route. In 1991, it was commissioned as PA 222. PA 145 was extended south of the US 22 freeway to the I 78/PA 309 overlap near Lanark.
