Chelmsford's first school for the deaf was established in 1866, with a focus in [[oralism]]. There was a maximum capacity of eight students at a time. This pioneer school was eventually closed in order to make way for the formation of a larger deaf school in [[Rowley, Massachusetts|Rowley]] known as [[Clark School (Rowley, Massachusetts)|Clark School]].<ref name=":0" />

Both the [[Middlesex Canal]] and [[Middlesex Turnpike (Massachusetts)|Middlesex Turnpike]], major transportation routes, were built through Chelmsford in the first part of the 19th century.

Chelmsford was the birthplace of the Chelmsford Spring Co. in 1901, which later became the Chelmsford Ginger Ale Company, acquired by [[Canada Dry]] in 1928. The [[ginger ale]] plant, rebuilt in 1912 after a disastrous fire consumed the original plant, stood on Route 110 until its demolition in 1994. The Chelmsford brand of golden ginger ale continued to be manufactured by Canada Dry for decades. It is currently manufactured by [[Polar Beverages]] for [[DeMoulas/Market Basket]] supermarkets, based out of neighboring [[Tewksbury, Massachusetts|Tewksbury]].<ref>{{cite web |title=A taste of the town's history |date=July 24, 2008 |access-date=March 15, 2012 |publisher=GateHouse Media |url=http://www.wickedlocal.com/chelmsford/news/x390637371/A-taste-of-the-towns-history |url-status=dead |archive-url=https://web.archive.org/web/20130729032922/http://www.wickedlocal.com/chelmsford/news/x390637371/A-taste-of-the-towns-history |archive-date=July 29, 2013}}</ref>
