From the bridge, NY 182 runs across the city of Niagara Falls, following several local streets as it makes its way to an intersection with U.S. Route 62 (US 62) in Wheatfield.

From here, the route heads south on Whirlpool Street, a two-lane, at-grade road that parallels the Robert Moses State Parkway through most of the city.

The road passes a handful of housing tracts before crossing Cayuga Creek and entering another commercialized area on the southern edge of Niagara Falls International Airport.

[4] In 1926, the New York State Department of Highways began developing plans to extend Porter Road southeast to Niagara Falls Boulevard (then-NY 34).

Robbins indicated that the state had planned to construct the rest of the Porter Road extension in 1930, providing the city with another route to the new airport.

[9][10] While state maintenance of Porter Road was confined to the part outside of Niagara Falls, NY 18D continued westward through the city to the Whirlpool Rapids Bridge by way of several city-maintained streets.
