Question: When do sidewalks get crowded on the Las Vegas Strip?
About the article "Las Vegas Strip", section "Pedestrian traffic".

Candidate passages:
Pedestrians can walk the length of the Las Vegas Strip with wide sidewalks in many places.
Sidewalks can get crowded in the evenings and early mornings, especially on weekend nights.
Crowds also gather near the outdoor shows at The Mirage, Treasure Island and Bellagio.
To improve pedestrian safety and help alleviate traffic congestion at popular intersections, several pedestrian footbridges were erected.
Some feature designs which match the theme of the nearby resorts.
The Tropicana – Las Vegas Boulevard footbridges were the first to be installed, and based on the success of this project additional footbridges have been built on Las Vegas Boulevard at the Flamingo Road intersection connecting Bellagio, Caesar's Palace, Bally's, and The Cromwell; between The Mirage/Treasure Island and The Venetian, and at the Las Vegas Boulevard-Spring Mountain and Sands Avenue intersection connecting the Wynn with the Fashion Show Mall, The Palazzo and Treasure Island.
The latest to be completed connects Planet Hollywood, CityCenter and The Cosmopolitan at the Harmon Avenue intersection.
The following is a list of hotels located on the Las Vegas Strip. 
The Strip today.
While not on the Strip itself, the Las Vegas Monorail runs on the east side of the Strip from Tropicana Avenue to Sahara Road.RTC Transit (formerly CAT or Citizens Area Transit 1992–2008) provides service on the Strip with double decker buses known as The Deuce.
The Deuce runs between Mandalay Bay at the southern end of the Strip to the Bonneville Transit Center (BTC) in Downtown Las Vegas, with stops near every casino.
RTC also operates an express bus called the Strip and Downtown Express (SDX).
This route connects the Strip to the Las Vegas Convention Center and Downtown Las Vegas to the north, with stops at selected hotels and shopping attractions.
Several free trams operate on the west side of the Strip:  Mandalay Bay Tram connecting the Mandalay Bay, Luxor, and Excalibur  CityCenter Tram connecting the Monte Carlo, Crystals, and Bellagio  Between Treasure Island and The Mirage Taxis can only stop at hotel entrances or designated spots, so when planning to get somewhere, passengers inquire as to which hotel or taxi stand is closest to the intended destination.
Before CAT Bus came on in 1992, mass transit on the Strip was provided by a private transit company, Las Vegas Transit.
The Strip route was their only profitable route and supported the whole bus system. 
RTC Transit operates a grid-type system within the Las Vegas Valley, which includes the four incorporated cities of Las Vegas, North Las Vegas, Henderson, and Boulder City; in addition, the remaining service area is in unincorporated Clark County under the Las Vegas Township, which includes Enterprise, Paradise (home of the Strip), Spring Valley, Sunrise Manor, Whitney (formerly East Las Vegas) and Winchester.
The system's three busiest routes, The Deuce on The Strip, Strip & Downtown Express (SDX), and Route 109 Maryland Parkway, provide service to the Las Vegas Strip and McCarran International Airport, respectively.
Approximately 40% of Clark County residents do not live within close proximity of a bus stop.RTC Transit also operates special routes for occasions such as sporting events at Sam Boyd Stadium.
