Cedar Crest Boulevard

Cedar Crest Boulevard, colloquially known as Cedar Crest and The Boulevard, is a major north south highway in Lehigh County, Pennsylvania in the Lehigh Valley region of eastern Pennsylvania. South of Interstate 78 (I 78), the road is part of Pennsylvania Route 29 (PA 29). North of it, the road becomes State Route 1019 (SR 1019). The boulevard is 9.5 miles in length and passes through Allentown, the third most populous city in Pennsylvania and county seat of Lehigh County. Its southern terminus is in Emmaus at Chestnut Street and its northern terminus is in North Whitehall Township at Mauch Chunk Road. It also is a junction onto I 78, a major east west highway between Lebanon County in the west and the Holland Tunnel and Lower Manhattan in the east. Cedar Crest Boulevard is home to many Lehigh Valley attractions, including two large rival high schools, Emmaus High School and Parkland High School, and the main campuses of Lehigh Valley Hospital–Cedar Crest and Cedar Crest College, Dorney Park & Wildwater Kingdom, Lake Muhlenberg, Lehigh Country Club, Lehigh Parkway, Muhlenberg College, and Trexler Park all border the boulevard. The boulevard is a prominent road for Allentown area commerce, including numerous strip malls, restaurants, and commercial establishments.

Cedar Crest Boulevard begins at an intersection with PA 29 (Chestnut Street) in Emmaus in Lehigh County, heading northwest as a two lane undivided road that passes through residential areas to the southwest of Emmaus High School and then through a section of Upper Milford Township. It then crosses the border between Emmaus to the east and Lower Macungie Township to the west and curves north as it enters Lower Macungie Township, where it crosses Little Lehigh Creek and then a mix of fields, woods, and homes and passes to the west of Lehigh Country Club. PA 29 then crosses into Salisbury Township and widens into a four lane road that passes between Lehigh Valley Hospital–Cedar Crest to the west and an office park to the east. Cedar Crest Boulevard becomes a divided highway and comes to an interchange with I 78/PA 309, where PA 29 ends and the road becomes SR 1019. Past the interchange, SR 1019 becomes a two lane undivided road, passing through several suburban residential neighborhoods before entering South Whitehall Township. Cedar Crest Boulevard comes to an intersection with a one way pair carrying PA 222 in a business area in Dorneyville just east of Dorney Park & Wildwater Kingdom. The Da Vinci Science Center is located at the northeast corner of PA 222 southbound and Cedar Crest Boulevard. Following this, the road serves as the border between South Whitehall Township to the west and the Allentown border to the east and west of Cedar Crest College. Cedar Crest Boulevard continues near homes and businesses in the western part of Allentown as a three lane road with a center left turn lane, crossing Lehigh Parkway, and then forming the eastern border of Trexler Park. SR 1019 then crosses SR 1002 (Tilghman Street) in a commercial section of Allentown and then continues through residential areas as a two lane road and entering South Whitehall Township. The road comes to an interchange with the US 22 freeway and then enters business areas. After crossing SR 1006 (Walbert Avenue) in Wennersville, Cedar Crest Boulevard passes through a mix of farmland and woodland with some development. The road crosses Jordan Creek and then under Norfolk Southern's C&F Secondary before passing Parkland High School to its east. SR 1019 then continues through rural areas and enters North Whitehall Township, where it comes to its northern terminus at an intersection with SR 1017, which is also known as Mauch Chunk Road. PA 229 was paved by 1930. By 1950, however, the PA 29 route number was removed, and it was renamed Cedar Crest Boulevard. PA 29 was designated onto a portion of Cedar Crest Boulevard south of US 309 (now I 78/PA 309) in the 1950s.

Two of eastern Pennsylvania's largest public high schools, Emmaus High School in Emmaus and Parkland High School in Allentown, are each located off Cedar Crest Boulevard roughly 9 mile (14 km) apart. In high school football, the two rival schools play each other in a game known as the Battle of Cedar Crest Boulevard. The winner of the game each year is awarded the Battle of Cedar Crest Boulevard trophy.
