Debris is being removed today from the downtown Shelton fire site. Some large trucks are being loaded with building remnants and the burnt-debris removed to an off-site location. The removal work would seem to indicate any problems with smoldering debris that could ignite \u2014 or hotspots \u2014 have ended on the property. Due to the work, Howe Avenue between Center Street and Bridge Street is expected to be closed until 4 p.m. today. The Derby\/Shelton Bridge is open. The short section of Bridge Street that connects Howe Avenue with the post office parking lot has been closed since the fire.
