A transportation board has approved a plan to build a new Tappan Zee Bridge.
The New York Metropolitan Transportation Council approved the project on Monday.
The county executives of Westchester, Rockland and Putnam said previously they would vote in favor of the project.
Their vote was crucial for the project to qualify for federal funds.
New York Gov. Andrew Cuomo had been gathering the support of other officials. He will speak on the project later Monday in Piermont in Rockland County.
Under the current plan, the bridge will have a dedicated bus lane during rush hours.
Cuomo has agreed to the formation of a task force that will make mass transit recommendations.
The environmental group Riverkeeper on Friday criticized officials for giving only three days' notice for the vote.
