Along the lines of the above comment by Everett Lueck, I would add the following.
The first engineering firm advised them to replace the Lobato bridge with a new bridge. A load test might prove that they don’t need a new bridge. Spending another $50,000 on a load test that might save $5,000,000 needed for a new bridge seems like a wise choice to me.
If the load test is favorable, they could have the bridge back in service before September. If they just went with the general assumption that the fire made a new bridge necessary, not only would the cost be very major, but it would also present a delay in resumed operation lasting for the rest of this season and possibly into next season. In my opinion, the load test should have been the first thing they did.
