Sean Logan, CEO of the Pennsylvania Turnpike Commission since 2015, resigned Thursday to pursue an unnamed public service job, the commission reported in a release.

Logan, from Plum, Pa., listed as his accomplishments a 70-mph speed limit along the 552-mile toll road, a still ongoing widening project, and a safety awareness campaign to protect workers. A debacle on the turnpike also occured during his watch in January 2016, when a major snow storm trapped hundreds of cars on the road in western Pennsylvania. Some motorists spent up to a full day waiting for rescue in their cars.

Governor Wolf is expected to appoint a new commissioner to the five-member board in the coming weeks.
