The street is open after months of closure due to sewer repairs.  Here is the advisory from the state transportation department.

UPDATE: DOTD advises motorists that the Town of Coushatta has completed repairs to their sewer line and US 84 (East Carroll Street) has been REOPENED.

It was late in May when a sewer leak caused a cave in on East Carroll Street.  Here is the Journal report on the closure.

The street had been closed almost six months.  This caused all the traffic that normally flows through town to be re-routed on Ringgold Avenue.
