PennDot District 11 will be closing the inbound (southbound) lane of the parkway north starting on Sunday August 3rd, 2008. The work that is being done is preventative maintenance because no significant repairs have been made on the roadway since it's opening in 1989. The project will preserve the roadway and bridges to prevent future more costly maintenance. Traffic will shift to the HOV lanes. The project is expected to be completed by mid-September.
