How much of a carbon footprint do marathons create?
When ever a marathon is arranged in a major american city, there are road closures due to the "runner’s route" being cordoned off for the course.
In other cities most folks "can" find an alternate route.
However, this Sunday, the California International Marathon is being held in Sacramento.
Unfortunately there are No Alternate routes for drivers. Mostly because the course starts near the bottom of the Folsom Dam. Cutting off the nearest bridge crossing across the American River, there are no other crossings for 40 miles up above the dam, and no crossings 30 miles down the river that will not impede on the runners course.
Some of the cross streets of the course, there are police that will permit a few cars at a time to cross the course. Folks trying to get to the other side have to line up and wait for the next break of runners to let a batch of cars through.
Last year there were lines of cars at all the designated course crossings up to 3 miles long, not including the bottleneck at the actual crossing street.
On several occasions ambulances were stuck in these bottlenecks.
Anyway, how much gasoline is wasted and converted to air pollution because the CIM still can’t figure out how to erect a "temporary" pedestrian overpass for the course runners, even if its only one or two temporary bridges to permit through traffic to continue without impediment?
