Estimate the Deh Cho Bridge's cost.

The Deh Cho Bridge is being financed with a $165 million bond issue to be repaid over 35 years, and with additional funds provided from current GNWT appropriations. This calculator is my effort to show the costs of that funding, and other Bridge expenditures, over that 35 year period and (as an example) for the first year of operations.

Some things are unknown - the major variable is the estimated level of freight traffic that will generated by existing and proposed North Slave mines. Adjust the options (more are available by clicking the "advanced options" checkbox) and press Calculate to see the results of different assumptions. The 35-year totals have been converted to 2011 dollars using a default 2% inflation rate - the actual dollar figures will grow larger as the years go by. Numbers have been calculated by your friendly neighbourhood NorthernRaven, and come with no warranty!

Using data from the Department of Transportation's Weigh-In-Motion scale, which breaks traffic down by axle counts, here is the hypothetical shortfall to the GNWT ("Net Cost") for previous years had the bridge existed, given the assumed tolls from that year's traffic. The variability comes from the fluctuating amount of mine freight.
