No. There's no bike lane on the Strip.
The Strip is too crowded with cars, trucks, tour buses, public-transportation buses, stretch limos, billboards on wheels, cabbies in a perpetual hurry, motorcycles, and motorcycle police -- many drivers rubbernecking, snapping photos and text messaging on cell phones, and tipsy on free booze – for there to be any room for bike lanes. There aren’t even any shoulders or "sharrows" (shared lanes with arrows), which makes it tough when a car breaks down on the Boulevard.
However, since the Strip is flat as a mackerel, cyclists can, when traffic isn’t stalled or backed up, maintain cruising speeds. With all the traffic lights, even aggressive drivers can’t get going much faster than a cyclist can, so drivers tend to merge with cyclists who keep up with traffic. Indeed, police patrol the Strip on bicycles safely (though drivers tend to pay attention to cops more than civilians, no matter what kind of wheels they’re riding); if they can do it safely, so can visitors.
That said, however, expert cyclists of our acquaintance strongly recommend against riding on the Strip in heavy city traffic. Some admit that you can ride relatively safely at first light, before the Strip gets congested. But you still take your life in your hands. At around 6:30 a.m. in March 2009, a 32-year-old Las Vegas woman hit and killed a 55-year-old cyclist on the Strip around Russell Road; she was drunk at the time and fled the scene, but was quickly arrested. (Her case has been continued several times, so there hasn’t been a resolution yet.)
If you do ride on the Strip, here’s the rest of what you need to know. Riding on sidewalks is against the law. Helmets are mandatory. Cyclists are advised to wear bright reflective strips or patches on backs, arms and legs. And carrying water is a must any time of year; it’s so dry year-round that dehydration can set in quickly.
