From The Story of Dartmouth, by John P. Martin:
The names of Ochterloney and Quarrell were commemorated by streets in downtown Dartmouth. The extension of the first named thoroughfare marked the beginnings of the present no. 7 highway.
From the old town-plot boundary, it veered to the north beyond Pine Street. Opposite the Greenvale Apartments, the antique stone-house demolished only recently, and apparently built “on the bias”, probably fronted the original line of Ochterloney Street as it continued through the property, now occupied by the Nova Scotia Light and Power plant, and headed for the millstream flowing from the lakes.
This road then bridged the stream near the western end of the circular-dam (which then did not exist) and ran diagonally to the rise of Prince Albert Road, just below Hawthorne St. Mounded evidence of this route used to be exposed whenever Sullivan’s Pond was drained.
At Silver’s Hill, the slope no doubt originally extended down to the lake shore. Pioneer trails generally avoided lowlands. Hence this “new” road to Preston followed the broad path still seen on the hillside below Sinclair Street, until it emerged around the bend at that bay of the lake called by Mi’kmaq “Hooganinny Cove”.
The causeway-bridge over Carter’s Pond at the town limits, was very likely built during the time of the Maroons, for the road is shown on military maps as early as 1808, indicating that this section of highway had been constructed some years previously.
From the vermilion color of the protective wooden railing, this crossing was long known as “First Red Bridge” to distinguish it from “Second Red Bridge” with similarly colored railing, built about 1826 across the bay of Lake Mic Mac near Miller’s Mountain.
