This 2009 technical amendment expands the boundary to add the Morehouse Bakery Building, built in 1907.","why_significant":"The district was the industrial heart of a planned manufacturing city, one of the best-planned projects of its kind in America at the time. Its mills, canal, dam and bridges show the evolution of industrial architecture and technology from granite rubble mills to reinforced concrete. The Morehouse Bakery adds the story of large-scale wholesale baking and local employment.","narrative":"Lawrence's North Canal district is a mile-long, 60-acre tract of mills, bridges, streets and hydraulic works laid out beginning in 1845 by the Boston-based Essex Company. Water from the Great Stone Dam, completed in 1848, fed a 5,330-foot canal that powered large brick textile factories for a planned city. The surviving buildings show how industrial design changed over time, from early granite rubble mills to flat-roofed brick mills and reinforced concrete, with changes driven by steam power, fire insurance requirements and ventilation systems. Thirteen bridges cross the canal and river, including the 1887 Union (Duck) Bridge and the 1918 Central Bridge. This 2009 amendment extends the period of significance to 1959 and adds the Morehouse Bakery Building, built in 1907 as a wholesale bakery that ran until 1976. It employed many workers after the textile strikes and supplied bread to the Merrimack Valley. The district is recognized for its industrial history and architecture.","period_of_significance":"1845-1959","architect_builder":"Essex Company (developer; Charles S. Storrow); Charles T.
