NEW ORLEANS — A federal judge has dismissed a lawsuit over a police blockade that kept back a few Hurricane Katrina victims from crossing a bridge out of New Orleans in the storm’s aftermath.

U.S. District Judge Mary Ann Vial Lemmon on Monday ruled that concluding the Crescent City Connection to pedestrians after the Aug. 2005 hurricane did not amount to an “unreasonable restraint of liberty.”

Mary Ann Vial Lemmon had ruled in 2007 that authorities didn’t violate Tracy and Dorothy Dickerson’s constitutional right to travel by means of stopping them from crossing the Mississippi River Bridge to escape the aftermath of the hurricane Katrina. The residual issues included whether police used excessive force and whether the Dickersons’ freedom-of-assembly and the same protection rights were violated.
