Old Baltimore Pike is a road in the U.S. state of Delaware. The road, known as New Castle County Road 26, runs from Maryland Route 281 (MD 281) at the Maryland state line south of Newark, Delaware, and continues east to Christiana, ending near Delaware Route 1 (DE 1). The road is paralleled by Interstate 95 to the north and U.S. Route 40 to the south. The Old Baltimore Pike was built before 1720 and connected Elkton, Maryland, to Christiana. It was a turnpike called the Elk and Christiana Turnpike between 1817 and 1838. In the past it served as a major connection between Philadelphia and Baltimore.
