This will do wonders for traffic for the 20 years it will take to get built.

They have been building a light rail line in Toronto for the last 15 years and it is still not finished. It runs right across the city but there is only one line. This looks like it has a few connecting lines. Traffic in Toronto anywhere near where they were building that line was a disaster for years.

Hopefully it will be an improvement once it is done but during construction it can be a nightmare.
