I have no problem with your having a bridge. I have a problem with you trying to justify a pork project gone wild.
Pork is in the eye of the beneficiary (it's not my bridge; I live over 300 miles from Redding). All I am telling you is that there are more beneficiaries than the number who use the bridge. The benefits are hard to quantify but I would bet that the local hotel industry and recreation operators have benefitted from the bridge helping dispel the notion that Redding is a hot, dusty, dump overrun with farm workers and therefore not worth visiting.
