Canal Bridge

PHOTOGRAPHER’S JOURNAL: It has been called the first "industrial park" in Connecticut, a place designed and built, not for a particular company or manufacturer, but with the aim of offering for sale multiple factory sites with power to turn machinery, and transportation to move goods for visionary manufacturing entrepreneurs. At it’s center was a five-and-a-quarter mile canal that allowed barges heaped with goods for market to more easily pass the falls and shallows below Enfield on the Connecticut River. 

In 1827, when work was begun, hopes were buoyed by the transformative success of New York's Erie Canal, two years earlier. Unlike that canal, where barges were pulled by draft animals along a tow path, the new canal was structurally reinforced to withstand steam-driven tug boat traffic. The project would open the single greatest bottleneck in the passage of goods along the Connecticut River all the way into Vermont, and it would sustain the commercial viability of Hartford against the competing interests of New Haven which were then at work on the Farmington Canal. Canals were being planned everywhere. There were plans for a canal between Albany and Boston.

The new canal would be designed with locks to raise and lower boats thirty feet along its course. It required the building of a large dam on the river and an aqueduct to carry canal water 104 feet across Stony Brook to feed apertures with steady flow past mill wheels at five factory sites. The passion to move goods by canal boat faded quickly as the steam that had begun powering tug boats along the Connecticut River began powering locomotives at greater speed with fewer interruptions over evenly graded tracks through the same valleys where the rivers flowed. Did this bridge once swing to admit visitors from the railroad to the right over a canal becoming less busy? Though the canal’s value for transportation diminished, it’s value for power generated increased as mill wheels became turbines and later as turbines turned electrical generators. The Windsor locks were a monumental undertaking; the first time Connecticut River water had powered mill wheels, one of the largest construction projects ever attempted in the state, and it grew to be a community.
