If you follow the state routes from any of the exits off Interstate Route 495, you can easily find your way to the library. After you cross the Merrimack River, you are in downtown Haverhill. Take a right onto Ginty Blvd. Take a right at the bottom of the exit ramp, onto Route 110 west. Turn right onto Stage Street, just before the Court House and before the next set of lights.
Parking lot is on the left.
