WALKER — Firefighters in Livingston Parish battled two brush fires Wednesday afternoon. Fire crews were working to put out a brush fire off of Florida Boulevard in Walker.

It was re-opened around 9 p.m.Shortly before 6 p.m., a second brush fire started on Debbie Lane in Denham Springs. This was a "fairly large field fire" that was put out very quickly, fire officials said. A cause was not determined. Ambulances stood by at both scenes, but no injuries were reported. Permalink| Comments
