Juncta Junctions of Erie and Champlain Canals in Cohoes, NY

1825: (Satellite)

1862: (Satellite)

The Champlain Canal joined the Erie Canal in Cohoes to access the Eastern Terminus and Lock #1 at the Hudson River. 

It is not too often that an 1893 topo map is not old enough to show something. This shows the 1862 enlarged canal rather than the original 1825 canal.

Fortunately, this reference shows both of the old canals and the New York State Barge Canal.

Historic Canal Routes Around Cohoes Falls and Canal Map of the State of NY Lock and Power Stations

Historic Canal Routes Around Cohoes Falls showing the Original and Enlarged Erie Canal Routes.  The enlarged Erie Canal had 72 total lift locks and 16 of these were in Cohoes-Watervliet area and the greatest concentration of locks along the Erie Canal that reduce shipping time from New York City to Buffalo from three weeks to just eight days the cost per ton of transporting cargo from New York City to Buffalo also dropped from $100 to less than $10 with it's peak year in 1855 when 33,000 commercial shipments took place at one time more than 50,000 people depended on the Erie Canal for their livelihood.

Enlarged Erie Canal : In 1837, New York State began a project to enlarge the canal by making it wider (70’ vs. 40’), deeper (7’ vs. 4’), and replacing the single chamber locks with double chamber locks to permit two‐way traffic at each lock. The Original Erie Canal had 19 locks in Cohoes; the Enlarged Erie Canal reduced this to 10 locks. Of those locks (from Lock 9 near Alexander St. to Lock 18 on North Mohawk St.), portions of all remain visible except Lock 13.

juncta  Painting of 'Juncta' by John Hill, 1834 NY Historical Society

The intersection of Saratoga and Main Streets, at the southern end of Cohoes, marks “Juncta,” a once lively neighborhood where the Erie and Champlain Canals came together. This 1834 view shows the first of a closely spaced series of 18 Erie Canal locks that lifted and lowered boats past Cohoes Falls.

Given the date and the lock numbers, I think this was the junction between the enlarged canals. But it has no identifying landmarks, so I used the above topo map to determine the location.
