Both names recall the buried conduit that carried Brooklyn’s water supply.
North Conduit Avenue is named for the conduit of the Brooklyn Waterworks, known as the Ridgewood Aqueduct, which fed Ridgewood Reservoir; the road was built on its former right-of-way. The aqueduct stretched 25 miles out to Massapequa in Nassau County. This station opened in 1883 under the name Aqueduct, and the neighbouring racetrack, which held its last races in June 2026, was named after the same aqueduct.
