据拉斯维加斯太阳报报道，拉斯维加斯热带大道上的人行天桥新建的六座自动扶梯将增加419573美元的开支，为此内华达州运输局十分不满，尤其考虑到自2003年以来一直在建的工程花费已经超过3千万美元。拉斯维加斯会展中心（Las Vegas Convention Center）为这些工程投资1900万美元，其余部分由国家交通部承担。一开始总承包商给出了较低的报价，但随后发现原本计划汇总的成本较低的自动扶梯与工程的诉求不符。而新的扶梯设备则由奥的斯电梯供应。

　　PRICE OF ESCALATORS OVER LAS VEGAS AVENUE DISPLEASES

　　Sixteen new escalators to pedestrian bridges over Tropicana Avenue in Las Vegas will cost an additional US$419,573, and the Nevada Transportation Board is unhappy with the rising costs associated with the overall US$30-million project that has been in the works since 2003, the Las Vegas Sun reports. The Las Vegas Convention Center is funding US$19 million of the project, with the state Department of Transportation funding the rest. The general contractor initially gave a lower price estimate before realizing the lower-cost new escalators were not compatible with the project. The new units are being ordered from Otis.
