Powerful congestion pricing supporters plan to sue Gov. Kathy Hochul over her 11th-hour pause of the first-in-the-nation tolls, according to two lawsuit drafts obtained by The Post Wednesday.

The two lawsuits — which sources said will be filed Thursday in Manhattan Supreme Court — will mark the first legal challenges to Hochul’s decision that scrapped the plans just days before $15 tolls were to be imposed on drivers entering Manhattan south of 60th Street.
