PORTLAND — Two of the Congress Street interchange northbound on-ramps for the Interstate 295 bridge will be closed Tuesday.

The Park Avenue and Congress Street on-ramps will be closed but the off-ramps will remain open.

The Maine Department of Transportation recommends the Fore River Parkway, Forest Avenue or Franklin Street on-ramps as alternatives.

The recent warm weather has been good for the bridge rehabilitation project. Contractors have gotten a head start on the $7.9 million project.

MDOT estimates that the bridge work will be finished in September and that night paving operations will end in October, depending on the weather.
