Unless you spend the bulk of infrastructure money on existing roads and bridge repair and resurfacing, the roll out will be slow. Building new highways and bridges takes years due to acquiring land, moving multiple utilities, engineering etc, etc. Both new and repair of existing infrasturcture is needed but it is not a jump start for employment and the economy. Note the street and highway construction in your area and see how slow it progresses. The construction is bogged down with local, state, and federal permits and regulations. But we will take any and all jobs infrastructure will provide. Don't even think about rail projects for another 5 to 10 years.
