Construction Phasing

This 18-month project will be split into several phases and work areas. The initial phase of construction, which is expected to last through summer 2023, will focus on the northern three miles of the work zone (MP 35.5 – MP 39.0) by adding passing lanes, right turn lanes, reconstructing the bridge over Rock Creek, and performing major rehabilitation or reconstruction of cracked and distressed pavement.
