The Niagara Scenic Parkway (reference route 957A), formerly the Robert Moses State Parkway, runs along the Niagara River. At one time, the Lake Ontario State Parkway would have extended westward to intersect it near Fort Niagara; the only indications of this are some barely visible stub ramps at the northern end, and the spur ramps to Fort Niagara. Various portions of the parkway have been removed and/or downgraded. The portion of the Parkway under the Rainbow Bridge near the falls was removed around 1980, and the portion north of there was reduced to two lanes in 2001 as part of a very slow conversion of the other two lanes to a bike path. The portion from the Rainbow Bridge to Findlay Drive was closed around 2020. The remaining northbound section of the southern section into the park was converted into a "Riverway" and the interchange turned into a roundabout in 2015.
