The authority board rescheduled its meeting from Friday afternoon to Tuesday.
The Unshackle Upstate business group and a Republican assemblyman accused the authority of trying to sneak in the vote while the public was focused on Superstorm Sandy recovery.
Earlier this year, the agency proposed what it termed a "modest" 45 percent increase.
Republican Assemblyman James Tedisco of Schenectady said Thursday the authority clearly doesn't want the public to see it enact a hike that truckers say will boost costs for all New Yorkers.
The Thruway Authority hasn't provided an agenda for the meeting.
