Expand the Las Vegas monorail to the airport and downtown. This would turn the system into a viable mass transit system that actually goes somewhere and fulfills a need in the Las Vegas valley.
Why is this important?
The Las Vegas monorail was a great idea that because of political pressures wasn't implemented to its full potential. In its current form the system doesn't service visitors effectively, because it doesn't go to the airport or downtown. Expanding the system would create jobs for a state with the highest unemployment rate in the country and transform the current system into a viable, effective system that would serve the needs of transporting Las Vegas visitors and provide a hub for future expansion to the rest of the Las Vegas valley.
