aggregate mostly. blame the WW2 era law, The Jones act for that one. Rail is at capacity with containers, and no ability to get rock by ship from the midatlantic at a reasonable cost because of the Jones Act- must use American made ships between US cities or territories. Barges haven't been made here for 60 years. It's $40/ton to move rock from Norfolk to Savannah, but $23/ton from Nova Scotia. Without the Jones Act you could get what is needed by ship for $10/ton or so from Norfolk and quickly. We are buying stone from Nova Scotia now to begin a large concrete project in September-crazy times. As Larry Summers said on CNBC recently, if the administration wants to help inflation, get rid of the Jones Act, and Tarriffs. They are all taxes on the American consumer.
