Not sure of the angle for claiming on "costs of stalled traffic" (is that lost revenue?), surely the brunt of that loss is on the commercial concerns of the boat operators themselves? If $1bn were the 'true costs' then clearly there are a lot of costs in running the canal over a year. It seems like the number is highly inflated, on face value. Not an expert, just an observation.
