An I-40 bridge over the Mississippi between Arkansas and Tennessee remains closed after a fractured support beam was found in early May. The closure disrupted river and road traffic, with 62 vessels and 1,058 barges queued when the river was first shut.
Extended disruption at a key Mississippi chokepoint raises barge delays and freight costs for grain flowing to New Orleans, which can widen basis and lower farm bids north of the bridge.
