Roadwork is set to begin (Tomorrow/Wednesday) on Route 22/322 in Juniata County as PennDOT starts a highway restoration project between the Arch Rock and Mifflintown exits. Drivers can expect alternating lane closures in both directions as crews begin saw cutting to replace concrete slabs. Long-term lane closures will follow for milling and resurfacing. The $2.9 million project is expected to finish by late July, weather permitting. Between now and then, if you must travel through that area, you should plan for delays.
