Lehigh Street is a major road that connects Emmaus, Pennsylvania in the west to Allentown, Pennsylvania in the east in the Lehigh Valley region of eastern Pennsylvania. The road is one of six roads that enter and depart Allentown, the third-largest city in Pennsylvania.
Lehigh Street is one of several major Allentown-area exits off Interstate 78, which runs from Interstate 81 in Lebanon County in the west to the Holland Tunnel and Lower Manhattan in the east.
Lehigh Street also serves as a major commercial center for the Lehigh Valley. The Auto Mile, which includes approximately a dozen new and used automobile dealerships, is located on Lehigh Street's western border with Emmaus. As the road enters Allentown from the west, it passes Queen City Airport, an Allentown airport used primarily by small, privately owned aircraft. South Mall, an enclosed shopping mall in Salisbury Township, is located on Lehigh Street.
The Emmaus side of Lehigh Street is the location of Shangy's, a beer distributor with the largest selection of domestic and global beers in the nation, including over 3,000 selections overall.
