<P> The service roads of I - 495 are called the "Queens--Midtown Expressway" between the Brooklyn--Queens Expressway and Queens Boulevard, and the "Horace Harding Expressway" between Queens Boulevard and the Nassau County line . They are generally signed as such like any other city streets . It is common to refer to the service roads by these names--particularly Horace Harding--in local usage, for instance when referring to the location of a building along the road . The names may have been intended to refer to sections of the expressway proper, but current guide signs (and Queens residents) simply refer to it as the Long Island Expressway . </P> <P> The Horace Harding Expressway section follows the path of Horace Harding Boulevard (also previously called Nassau Boulevard), which was named for Horace J. Harding (1863--1929), a finance magnate who directed the New York, New Haven and Hartford Railroad and the New York Municipal Railways System . Harding used his influence to promote the development of Long Island's roadways, lending strong support to Robert Moses's "great parkway plan". Harding also urged construction of a highway from Queens Boulevard to the Nassau County Line, in order to provide better access to Oakland Country Club, where he was a member . After his death, the boulevard he helped build was named for him . Horace Harding was not related to the former President Warren G. Harding . </P> <P> Heading into Nassau County, the expressway sports a High - Occupancy Vehicle Lane (HOV), which begins at exit 33 and runs to central Suffolk County . In its run through Nassau, it is the only major east--west highway that does not interchange with the Meadowbrook or Wantagh state parkways, both of which end to the south at the adjacent Northern State Parkway, which parallels the LIE through the county . The two highways meet three times, although it actually crosses only once at exit 46 near the county line . I - 495 does, however, interchange with the Seaford--Oyster Bay Expressway (NY 135) as the east--west parkways do, and often has heavy traffic . In Suffolk County, the LIE continues its eight - lane configuration with the HOV lane to exit 64 (NY 112). At this point, the HOV lane ends and the highway narrows to six lanes; additionally, the concrete Jersey barrier gives way to a wide, grassy median, the asphalt road surface is replaced by a concrete surface, and the expressway is no longer illuminated by streetlights, reflecting the road's location in a more rural area of Long Island . </P> <P> From NY 112 east, the expressway runs through more rural, woodland areas on its trek towards Riverhead . Exit 68 (William Floyd Parkway) marks the terminus of the service roads, which are fragmented by this point . Exit 70 (CR 111) in Manorville is the last full interchange, as it is the last interchange that allows eastbound traffic on, and the first to allow westbound off . After exit 71 (NY 24 / Nugent Drive), the expressway begins to narrow as it approaches its eastern terminus . Until 2008, just before exit 72 (NY 25), the three eastbound lanes narrowed to two, which in turn narrowed almost immediately to a single lane at exit 73, which lies 800 feet (240 m) east of exit 72 . As of 2008, of the two lanes, one lane is designated for exit 72 and the other is for exit 73, which ends the squeeze into a single lane that formerly existed at exit 73 . At exit 73, all traffic along the expressway is diverted onto a ramp leading to eastbound CR 58, marking the east end of the route . </P>
