Considering the recent debate about transportation funding, some may be wondering whose responsibility it is to finance our roadway and transit systems. Well, if you live in Pennsylvania and drive its highways and bridges everyday, or use some form of public transit, then it is yours!  As a civil engineer in the state's transportation industry, I have an insider's view of the condition of the state's roads and bridges. Pennsylvania leads the nation in the number of structurally deficient bridges. Our roadways are deteriorating faster than they can be maintained. Mass-transit systems statewide are severely underfunded.
