MARTIN COUNTY— The Florida Department of Transportationcontinues to take samples of the southbound Roosevelt Bridge and likely will keep taking samples for the next few weeks to a month.
After samples are taken and examined, the agency will have a better idea on how to properly repair the southbound Roosevelt Bridge.
FDOT will likely have more information in the next two weeks on the contractor they plan to work with to repair the bridge as well as how much the repair will cost, said Beth Frady, FDOT communications director.
She said the agency is looking at contractors who have constructed or been qualified to do repairs on segmental bridges such as the Roosevelt Bridge.
"For reference, the bridge is nearly one mile long and the work to gather samples is being done across the entire facility in a methodical manner," she said.
It could be up to six months before the southbound Roosevelt Bridge is open to the public and motorists, FDOT officials said.

On July 4, FDOT opened portions of Dixie Highway that were previously closed for weeks following the closure of the north and southbound bridges.
Last month during a biannual inspection of the bridge, FDOT found a crack in the southbound span and closed the northbound and southbound bridges.
Further tests and investigating found corrosion causing steel tendons in the southbound span to rupture. Minor levels of corrosion were reported on the northbound bridge, which has since been repaired.
The northbound bridge is open for some two-way traffic; the southbound bridge is closed indefinitely.
Prior to the bridge inspection weeks ago, it was inspected in June 2018.
A heavily redacted 109-page inspection report dated August 2018 noted the southbound Roosevelt Bridge had "several longitudinal cracks" and there were cable clamps with wire ropes that had heavy corrosion.
The southbound span's load capacity had "no indication that deterioration, geometric changes or additional dead load occurred that would warrant a new load rating analysis."

The northbound span's superstructure — the portion of the bridge that supports the deck and connects one substructure to another — received an overall rating of "good." The substructure that supports the superstructure received a "satisfactory" rating.
