 Through much of this portion , the road is divided , with a tree @-@ lined median strip . Businesses , both local and national , line both sides of the road and traffic is heavy . It crosses some other major strips such as Niagara Falls Boulevard ( U.S. Route 62 or US 62 ) , a major contributor to traffic on Sheridan due to the proximity of the Boulevard Mall , and Millersport Highway ( NY 263 ) , which feeds the Amherst campus of the University at Buffalo . In Amherst it meets the Youngmann Expressway ( I @-@ 290 ) where NY 240 ( Harlem Road ) , reaches its northern end . Past the Youngmann development abates , green returns to the roadside and the median ends , although the road remains four @-@ lane and high @-@ volume . There is another pocket of development around the Wegmans supermarket north of Williamsville , which has seen some rapid growth in the last few years .
