The LaSalle Expressway (also known as the LaSalle Arterial) is a limited-access highway in Niagara County, New York, in the United States. It begins near the North Grand Island Bridge at an interchange with Interstate 190 (I-190) in Niagara Falls and ends just south of the Niagara Falls International Airport at Williams Road (NY 952V) in Wheatfield. The LaSalle Expressway is part of New York State Route 951A (NY 951A), an unsigned reference route; the other, portion is located along Niagara Street between the Rainbow Bridge and Fifth Street in downtown Niagara Falls. Most of this portion, which is not connected to the LaSalle Expressway, is also part of the signed NY 384. There are two lanes in each direction of the expressway, separated by a grassy median strip. Currently, only three exits exist on the expressway; however, the LaSalle was originally proposed as part of the Belt Expressway for the Buffalo–Niagara Falls area, stretching from the Rainbow Bridge in Niagara Falls south to Blasdell. The Milestrip Expressway (part of NY 179) in Blasdell and the LaSalle Expressway are the only portions of the loop that were constructed. The LaSalle Expressway was built over an old railroad grade in the 1960s and opened to traffic by 1971. Near its current eastern terminus, the LaSalle Expressway passes directly south of the Love Canal neighborhood. Route description The LaSalle Expressway begins at a trumpet interchange with I-190 in eastern Niagara Falls. It heads east from the junction as a four-lane freeway, passing through a predominantly residential area of the city. Not far from I-190, the highway connects to a spur leading south to the east end of the Robert Moses State Parkway, which serves as a riverside connector between the LaSalle Expressway and downtown Niagara Falls. The LaSalle continues on, connecting to 77th Street by way of a diamond interchange and Cayuga Drive with a partial diamond interchange before crossing over Cayuga Creek. About a quarter-mile (0.4 km) from the creek, the neighborhoods that had lined the highway abruptly end as the LaSalle Expressway passes through the remnants of the abandoned Love Canal neighborhood. At the eastern edge of the neighborhood, the expressway's four lanes narrow to two as the highway crosses into Wheatfield and follows what had intended to be exit ramps to an intersection with Williams Road (unsigned NY 952V) in a mostly commercial area of the town.
