Middletown merchant traders pushed for the clearance of the Saybrook Bar at the mouth of the Connecticut River, and later sought the creation of Middlesex County in 1785. The name 'Middlesex' was chosen because the intention was to make Middletown the head of a long river port, much as London was at the head of its long river port on the Thames in Middlesex County, England. The same persons also established the Middlesex Turnpike (now Route 154) to link all the settlements on the western side of the Connecticut, again with the intent of creating one long port.
