western segment still continues to Fifth Street as of 2008. In late 2011, an extension of the LaSalle Expressway past its western terminus at I-190 was mentioned by Niagara Falls Mayor Paul Dyster as a potential long-term solution to improve safety at the junction of I-190 and US 62. The construction of the LaSalle Expressway indirectly contributed to the Love Canal disaster. When the freeway was built along the southern edge of the neighborhood in the 1960s, it prevented the contaminated groundwater inside the former canal from escaping into the Niagara River. The trapped toxic water was then forced to the surface after the water table rose substantially following a 1977 blizzard.
