The estimated cost for renovating the idle international ferry terminal in Bar Harbor has grown by more than $2.5 million, but the Nova Scotia government says it will cover the higher expense. The provincial Department of Transportation and Infrastructure Renewal issued a statement Wednesday saying the projected cost for fixing up the ferry terminal, which Bay Ferries plans to start using in June for catamaran ferry service between Nova Scotia and Maine, is $8.5 million in Canadian currency, which is equal to roughly $6.4 million U.S. Earlier estimates Bay Ferries provided to the town of Bar Harbor, which owns the terminal, pegged renovation costs at about $5 million in Canadian currency, or around $3.75 million in U.S.
