So, let's suppose the cost for drivers of light vehicles is around 50 cents/km. That would make a one way trip approx. $3.50-4.50. That's not out of line with what many drivers are spending on one way commutes on the 407. Now, how much cost could drivers bear once the additional costs of subway tunneling are factored in? Is $5.00, $6.00 per one way trip over the top? I think not, since some travellers are spending far in excess of that for GO train or longer one way trips on the 407. I'd think $10.00 is a psychological barrier for a one-way trip on the expressway, yet some drivers are spending over $20.00 each way daily on the 407. I think the expressway would be a hit for HOV's such as coach buses and for heavy delivery vehicles for the time savings. On the 407 the per km cost for heavy vehicles is around 90 cents. These vehicles would make a large contribution to funding the amortized costs of building the tunnel, as well as operating costs. Oh, with regard to annual 407 profits, I'm not sure about current data, but I found this from a 2013 Toronto Star article:
Toll highway operator 407 International is reporting a 128 per cent increase in profit for the fourth quarter as it recorded higher average revenue per trip compared with the same period last year.
The company says net income was $39.3 million for the quarter compared with $17.2 million in the year earlier period. Revenues were $187.2 million, up from $172.8 million in the fourth quarter of 2011.
The company, which owns the private 407 Highway connecting several cities in the Greater Toronto Area, saw a slight decline in the total number of trips taken during this period to 29.2 million from 29.3 million in the fourth quarter of 2011.
However, average revenue per trip was $6.40 during the quarter, up from $5.89 year over year.
The company is owned by Cintras Infraestructuras S.A., a subsidiary of Ferrovial S.A, and partially owned by subsidiaries of the Canadian Pension Plan Investment Board and Montreal-based engineering giant SNC-Lavalin
