Crews on Tuesday filled in a small sinkhole under the Arthur Ravenel Jr. Bridge that raised concerns on social media over the holiday weekend.

Officials reiterated that the hole — approximately 3½ feet deep at Mount Pleasant's Waterfront Park — is not a threat to one of the concrete pillars supporting an off-ramp. It had been filled in before, only to re-emerge after rainfall.

The latest sighting on Memorial Day and the ensuing photographs caused a stir online amid rising concern about the integrity of Charleston-area bridges. A support cable failed in an Interstate 526 span over the Wando River earlier in the month, forcing the emergency closure of the westbound span.

Town Mayor Will Haynie said he met Tuesday with state Department of Transportation officials at the site of the hole that measured 5 feet long by 3 feet wide. The pillar is driven about 120 feet into the ground, the DOT has said.

"They confirmed (again) that they are not concerned about the structural integrity of the bridge support and asked the town to fill the hole," Haynie said on Twitter.

The town did that again Tuesday, packing it with rocks and then covering it with dirt. An employee with the Public Services Department said crews in the past had filled the hole only with dirt but Tuesday used rocks at the recommendation of the DOT. 

The town employee said Tuesday marked the fourth time crews have filled the hole in about six weeks.
