That’s a problem because Highway 1, unprotected by levees, connects critical oil and gas resources in booming Port Fourchon to the rest of the nation. Ten miles of the highway is now standing 22 feet above sea level on cement piles. But another 7 miles is not, and if less than half a mile of this highway succumbs to the 14-foot storm surges expected in the future, the highway will need to be shut down, cutting off the port.
Residents and business leaders are demanding that the federal government help pay to rebuild and elevate the additional section of Highway 1. Federal officials have provided scientific and technical expertise but will not contribute funding unless the state pledges to complete the road. Louisiana says it does not have the money. The dilemma facing this important lowland road is one shared by communities across the country as climate change begins to transform the nation’s landscape.
...Researchers at the National Oceanic and Atmospheric Administration, who started measuring tides in Louisiana in the mid-1800s, have analyzed the numbers for Highway 1, and they do not bode well. At today’s rate of sea-level rise the road would be under water roughly 22 days of the year by 2030...
