Expressway (NY 135). 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. 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 east of exit 72. , 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. HOV restrictions There is one HOV lane in each direction, in the median of the highway, between exit 32 (Little Neck Parkway), near the Queens–Nassau border, to exit 64 (NY 112), in central Suffolk County. From 6:00 am to 10:00 am and from 3:00 pm to 8:00 pm Monday through Friday, the HOV lanes are limited to busses, motorcycles, and Clean Pass vehicles without occupancy requirement and passenger vehicles with at least two occupants. Trailers and commercial trucks are always prohibited therein. Vehicles are only allowed to enter and exit the lanes at designated junctions. Originally, the HOV lanes were restricted to passenger vehicles with at least two occupants. Starting in 2006, drivers of certain hybrid vehicle models were allowed to use the lanes even if they were driving alone. By 2014, over one-third of all traffic on the LIE between exits 32 and 64 used the HOV lane
