Maine is the first Northeastern state to partially reopen its economy amid the coronavirus pandemic.
The state will allow some businesses - including drive-in theaters, barber shops and hair salons, dog groomers and car dealerships - to reopen from Friday.
Current restrictions, including no gatherings of more than 10 people and 14 day quarantine for out of state visitors, still apply.
The state currently has 1,000 infections and 51 deaths.
Meanwhile, Michigan will allow its construction industry to resume work from May 7. The state's governor extended the stay-at-home order last week until mid-May but lifted restrictions on some businesses amid criticism by some that she had been too restrictive in her lockdown.
They joins a number of other states - mostly in the South and Midwest - to lift coronavirus restrictions following weeks of mandatory lockdowns that have thrown millions of American workers out of their jobs.
Alabama, Ohio, Missouri, Montana and Iowa will slowly start opening their economies this week.
Minnesota, Mississippi, Tennessee, Colorado, Alaska, Georgia, Oklahoma, South Carolina and Texas have already partially reopened.
