at Weehawken, near the west shore of the North River, and thence
eastward a distance of 224 ft. to the Weehawken shield-chamber. It then
passes under the river through two cast-iron, concrete-lined,
single-track tunnels, with outside diameters of 23 ft., to a point under
32d Street, near Eleventh Avenue, in New York City, and thence through
two single-track tunnels of varying cross-section, partly constructed in
cut-and-cover, to the east side of Tenth Avenue. It then passes into the
Station Yard and terminates at the east building line of Ninth Avenue.
The work included the Station Yard excavation and walls from Tenth
Avenue to Ninth Avenue, and the retaining walls and temporary
underpinning of Ninth Avenue. The aggregate length of the line in this
Division is 2.76 miles.
