Question: How long is the bridge that NY 104 starts just east of? Passage:NY 104 begins at NY 384 just east of the Rainbow Bridge in downtown Niagara Falls and heads north and east across the county on its way toward Rochester. From Niagara Falls, the route travels in north-northeasterly direction along the Niagara Gorge as it heads into Lewiston and connects to the Robert Moses State Parkway and serves the Niagara Power Visitors Center, known as the Power Vista. Just north of the Power Vista, NY 104 meets I-190 at exit 25 via Upper Mountain Road (unsigned NY 954P). Continuing on, the highway has a junction with nearby NY 265 before descending the Niagara Escarpment toward the village of Lewiston. As the road heads down the ridge, it intersects the western terminus of NY 18 by way of an interchange.
