Why do American cities often have to take large public transport projects such as light rail and metro system to the voters but don’t have to do the same for massive highway and road construction?
Large road projects usually exist to keep the existing road network running, or to improve its relation to the rest of the city. Bridges need to be retrofitted, underpasses capped, tarmac replaced. They may be big projects, but they're really necessary to keep the system functioning like it is.
The Short Answer
Large road projects usually exist to keep the existing road network running, or to improve its relation to the rest of the city. Bridges need to be retrofitted, underpasses capped, tarmac replaced. They may be big projects, but they're really necessary to keep the system functioning like it is. A major public transportation network is an entirely new investment. If you don't do it, you don't it–there's no downside other than that you don't have the network. A comparable project would be the construction of an entirely new highway link (or in some cities, the removal of major highways), which is rare and nowadays often put to voters as well. Of note is that many major highway projects were initiated in a time when referendums for transportation were not as common.
