Expansion of the Heritage Rail Trail north along the Codorus Creek, called the Northern Extension, began in 2005 at John Rudy County Park and headquarters of the York County Department of Parks & Recreation. The Northern Extension is being completed in phases, with 4.3 miles from the County Park to Route 30 completed in 2015. Construction of the section from Route 30 to North George Street in the City of York is expected to be completed by the end of 2018. The City of York is undertaking the remaining distance to connect the Northern Extension to the mainline York County Heritage Rail Trail from North George Street to Philadelphia Street and should be ready sometime in 2019.
