The state's top transportation official says Wynn has adequately addressed traffic and transit issues surrounding its planned $1.7 billion casino project for the Everett waterfront.
Massachusetts Secretary of Transportation Stephanie Pollack, in a letter to state environmental officials, said she supports issuing a key environmental permit needed for the project to break ground.
The Friday letter follows one by state Attorney General Maura Healey requesting that officials deny Wynn's permit until a plan to address traffic around Boston's notoriously congested Sullivan Square is finalized.
Boston, Revere and Somerville, also filed letters Friday objecting to Wynn's permit application. The three cities are separately suing the state Gaming Commission over its decision to award Wynn a casino license.
Environmental officials are expected to decide on Wynn's permit by Friday.
