FACTBOX: Las Vegas Strip under construction

(Reuters) - Developers are expected to add about 23,000 luxury hotel rooms to the Las Vegas Strip between now and 2010.

That number has fallen by about half from a year ago as the weak economy and credit constraints led several developers to reconsider their plans.

Following is a summary of casino-hotel projects currently under construction:

-- Encore at Wynn Las Vegas: 2,034 all-suite hotel tower, 72,000-square-foot casino, convention and meeting space, restaurants, nightclub, swimming pools, spa and salon, and retail outlets.

Due to open in December.
