Two former officials linked to New Jersey Gov. Chris Christie’s office were sentenced Wednesday for their role in the 2013 Bridgegate lane closure controversy.

Bridget Anne Kelly, former deputy chief of staff in Christie’s office, was sentenced to 18 months in prison. Earlier in the day, Bill Baroni, former deputy executive director of the Port Authority, was sentenced to 24 months in prison.

The charges stemmed from the abrupt closure of local traffic lanes on the George Washington Bridge, one of the world’s busiest bridges, for four days in September 2013. The lane closures caused severe traffic delays and endangered commuters between Manhattan and New Jersey, court documents said.

Christie has not charged with a crime in relation to Bridgegate.
