Or conversely, look at how many houses Robert Moses took to build the LIE. Do you think a present-day Robert Moses could get away with the same tactics? I doubt it. Only way to increase lanes is to go up, and once you do that, a RUF guideway is much cheaper per mile than an elevated roadway.

You are looking at American history. I don't think there is much there to interest people outside the US. Have you travelled to any other countries?

Just a few. Norway, Sweden, the UK, Turkey, India, Belgium, Croatia, Brazil, the Netherlands. But big cities are the same worldwide. There's no room for extra lanes except to go up.
