PennDOT is informing drivers of the potential for short-term delays in both the northbound and southbound lanes of Interstate 99 between mile marker 26 in Blair Township, and mile marker 33 near the 17th Street Exit through the month of March. Beginning next Monday, to approximately Saturday, March 28th, the contractor will implement lane restrictions – from two lanes to one, and close shoulders on portions of I-99 to complete work, including highway markings, grading, delineation, sawing and sealing, and completion of the 17th Street drainage work. All work will be completed during daylight hours.
