The great age of road-building is only beginning. By 2050, we will have added 15 million miles of new road to the planet — a 60 percent increase in four decades over our current total, amassed over the past 5,000 years. Nine-tenths of that network will be built in the developing world – in the basins of the Amazon and Congo Rivers, and the jungles of South Asia and Oceania.
For the people of Bayou Corne, a small community in northern Assumption Parish, the first signs of trouble appeared in late May. Streams of bubbles appeared in the water in nearby Bayou Lofourche. Then in early August a series of tremors led to the discovery of a sinkhole. Since then that hole in the ground has continued to grow along with the concerns of local residents and the officials they are looking to for answers.
Louisiana’s Assumption Parish sinkhole caused the evacuation of 150 homes in early August and continues to threaten the area with possible explosions due to methane gas pockets. Property owners have not been allowed to return home yet, and businesses are at risk.
Texas Brine Co. began burning off natural gas Friday that was trapped in a water aquifer near a sinkhole in northern Assumption Parish, officials said.
This was the first time state, parish or company officials have been able to get gas to flow from four “vent wells” driven into the ground around the sinkhole in order to draw the dangerous gas out of the aquifer.
Located in the swamps between Bayou Corne and Grand Bayou south of La. 70 South, the sinkhole is more than 5½ acres in size at the surface and has prompted authorities to issue a standing evacuation order on Aug. 3 applying to 150 homes.
Fears that the trapped gas, which is colorless, odorless and potentially explosive, could accumulate to dangerous levels at the surface has further justified the evacuation order, parish officials have said.
