9:10 a.m. Message from DOTD (unrelated to Bayou Corne incident)

LA 70 Southbound at Pierre Part Bridge in Assumption Parish will be closed across the entire length of bridge on Wednesday, March 19th at 10:00 A.M. to 12:00 P.M. while DOTD crews perform a routine inspection on the bridge.

This closure will allow vehicles 12-feet wide or smaller to pass through the construction zone. Road is open for regular traffic but oversize vehicles must detour using LA 70 North to LA 1 South to LA 398 South to LA 662 South to US 90 West.

DOTD appreciates your patience and reminds you to please drive with caution through the construction site and be on the lookout for work crews and their equipment.

12 noon Update from the Office of Conservation

Texas Brine advised that the tagging of Cavern 3 (performed last Friday) was at 3,995′ (359′ from the cavern roof) which is 351′ drop from the tagging performed two weeks ago. As information becomes available, it will be shared here.
