An economic study of Baltimore’s Grand Prix finds that the event had a positive economic impact of $47 million. Sounds great until you compare it with the $70 million projection from Baltimore Racing Development last year.

The city made $1.7 million in tax revenues, far short of the $6 million projected, and moot when you consider the $6.5 million the city spent repaving roads (and the trees that were cut down, and the annoyance of road construction).

Still, the race has been deemed a net positive for the city (at least economically), and Baltimore can look forward to hosting the Grand Prix every summer for the next four years.
