PA Turnpike Chairman Sean Logan of Plum, PA, announced today that he is resigning from his Turnpike position to pursue other public-service opportunities, effective immediately.

"It is with mixed emotions that I step down from the PA Turnpike Commission, as I have come to know and respect my fellow commissioners and the entire senior-staff team. " Logan said.

Logan was first appointed to the Pennsylvania Turnpike Commission in 2013 and named chairman in January 2015.

He helped steer the Turnpike through a pair of significant, national-headline-grabbing events in 2016: a blizzard that stranded hundreds of motorists on the Turnpike in the Allegheny Mountains in January followed by an armed-robbery attempt at the Fort Littleton Interchange in March that ended in the killing of a toll collector and a security contractor - as well as the death of the offender.

In the coming weeks, Gov. Wolf expects to nominate a new Turnpike commissioner to fill the vacancy on the five-member panel. That nominee must be confirmed by at least a two-thirds majority of the state senate.
