The demolition of an existing building, that will pave the way for construction of a new complex for Center for Maine Contemporary Art, is scheduled to begin next week.

Rockland Main Street Inc. sent out a notice last week that advised downtown businesses that during the weeklong demolition, Winter Street, which runs off Main Street, will be one-way. Demolition is expected to begin Sept. 8.

Excavation for the new foundation for the arts center on Winter Street is tentatively scheduled for October.
