The total cost of the bridge component is roughly about a billion dollars. On either side, of course, we have to have customs plazas, both on the Canadian side and on the American side, and then on the Michigan side there is an interchange that connects to the interstate system.
Those pieces will comprise the DRIC crossing, the Detroit River international crossing project. As for the total of cost of that, right now we are doing the figures again because the work on the Michigan side was really delayed for a two-year period. We're bringing those numbers up to date, and we estimate that the cost will be a little bit above $2 billion.
As the deputy said, the objective is that we will go for a public-private partnership. We have done various rounds of soundings with the market, so the players, the P3 players, and they've indicated to us that they have an interest in the project, a big interest. I think the governor saw that in Toronto earlier this week at the P3 conference. We expect that they will be able to invest equity in the project, and that they probably would be able to invest enough to cover the costs of the bridge.
With that, the government would then have to look at how to cover the rest of the funding through appropriation. Tolls will be charged and tolls will be set according to the market rate at that time. We expect from the traffic analysis we've done—perhaps three times over now, and we'll update them again before we go out to market—that the project cost can be totally recouped within a concession period ranging about 35 to about 40, 45 years, and that it would be totally covered from the toll revenue. After that point, all the toll revenues are then gathered and put back into the infrastructure to make sure it's kept in good condition.
So there will have to be upfront support for the project, but the toll revenues will start to pay back very soon thereafter. The project, in fact most projects, will take about a five-year period right at the beginning for the traffic levels to basically firm up. At that point, the tolls start covering the actual investment in the project.
