PORTLAND — Maine Turnpike officials say the toll road’s bond rating reflects sound financial operations, an expectation of stable traffic and other improvements.

Moody’s Investors Service has affirmed the Aa3 underlying rating assigned to the Turnpike Authority’s revenue bonds and the agency’s stable outlook. The MTA also enjoys strong ratings from the nation’s other leading credit agencies. Standard & Poor’s assigns an A+/Positive and Fitch Ratings assigns an AA/Stable rating.

MTA Vice Chairman Lucien Gosselin says Moody’s affirmation speaks volumes about how the financial community views the Maine Turnpike Authority’s response to some questionable executive-level spending practices uncovered earlier this year.
