The cost of light rail is heavy at $34,311,927 per mile when elevated monorail of the kind Disney uses has lower overhead and maintenance and operating costs after construction. Mono-rail construction costs at maximum add up to be about $26,000,000 per mile at my last examination of costs. The good people of Seattle voted recently to extend their little system to be about 40 times its current length. Their monorail was constructed for the World's Fair in less than 11 months, start to finish, using older construction technologies and Mexican manufactured trains assembled with U.S.-made monitors and other parts as designed by Swedish engineer Alex Wenner Gren and his German partners. The system known as the Alweg operates with lasting efficiency.
Today, Bombardier of Quebec, Canada, owns this technology. Hitachi of Japan has developed a similar technology. See (www.monorails.org/tMspages/News.html) and take a look at the Kuala Lumpur, Malaysia, design by Hitachi. Also check out (www.monorails.org/tMspages/enviro.htmI) and take a look at these photos being creative and also Hiding-A-Pylon. I am the inventor of the American JET-Train (see U.S. Patents on the Web, Patent #5,651,318). This type of train would be too fast for a 10.9 mile run. Yet the cost would be less than your proposed light-rail system.
It is true that in cites like Salt Lake City where a lot of the city is spread out that public transit is more costly per person using it. All over Utah and the United States traffic has become a major issue. Don't squander tax dollars in haste to spend them. Light rail on the ground competes with other traffic on the ground. It does not solve the problems as readily. I noted a number of U.S. monorail patents happened to be owned by residents of Salt Lake City when I was performing my patent search. You have access to monorail talent in your own city. I hope Salt Lake City gets a monorail, a highway or higher way to travel above the earthly confusion of auto traffic. Clean and electric, the inside of the hollow beam can carry hidden fiber optic cables transmitting voice by light. Moving people and moving data and voice communications.
