Used to describe a traffic jam or traffic congestion due to road work, funded by the American Recovery and Reinvestment Act of 2009. This roadwork is often pointless and inefficient, but gets done anyway because the state has to fulfill a quota, otherwise it won't get equivalent funding during the next government handout cycle.
Now that exit 5 is being repaired, Joe's has to use exit 6 and go out of his way. Even though Joe's house is just three blocks past exit 5, using exit 5 would result in a 20 minute delay, thanks to the Stimulus Jam right below it.

The unexpected Stimulus Jam on I-95 resulted in crawling traffic and an extra hundreds of gallons to be burned.
