In 1992, a plan to construct a full-scale replica Star Trek's Enterprise on the Vegas Strip was scrapped, Gary Goddard of the Goddard Group shared online, complete with artist renderings of the anticipated scene.
The US$150 million project did not take off, however. Anthony Pascale from TrekMovie.com shares some insight:
...the Enterprise would have a tour of the ship with all the key areas, plus a restaurant in the crew mess, and there were ride elements including a "high-speed travelator that would whisk you from deck to deck." They also planned to develop additional attractions as the project went on.
Discussion of the economics of the project appear sound--it just didn't make sense to invest that much in the franchise in such a permanent manner--but such a sight would surely have been a welcome addition to the skyline.
