PORTLAND — The Maine Turnpike Authority is considering proposals that would hike tolls on the 109-mile toll highway.

The turnpike authority board is scheduled to take up the issue during its regular monthly meeting today in Portland. The board can vote on the issue or postpone a decision to a later date.

The turnpike authority says toll adjustments are necessary to raise additional revenue to cover the turnpike’s operating budget, maintenance and long-term debt service.

The agency has held six public hearings on different toll hike options.

The preferred option is to add $1 to the toll plaza in York, 75 cents in New Gloucester and West Gardiner, and 50 cents each at the Wells northbound and Gray southbound toll plazas. E-ZPass rates would also go up.
