City staff did a weekly inspection Friday of erosion control devices along Local Interstate Connector South.

The weekly inspection came five days after reassuring Bradley County Commissioners the project was in good standing with the Tennessee Department of Environment and Conservation.

Cleveland Director of Development and Engineering Services Jonathan Jobe said the stormwater department began monitoring the construction site in mid-May, when the contractor began moving dirt.

Some residents complained to county commissioners on Sept. 4 about mud flowing into Brymer Creek after heavy rainfall on Aug. 9 and 10. Since then, more erosion control devices were added to prevent more sediment from flowing into Brymer Creek. The new controls include more rock check dams to slow the flow into sediment ponds in basin areas at the bottom of a 4½-percent grade and a 10-percent grade.

“The goal is not to let it in any tributary to any stream,” Jobe said. “But since Brymer Creek is an exceptional waterway, it has to be protected even more.”

Many residents around McDonald opposed construction of the road for fear of increased commuter and truck traffic on Bancroft and Harriman roads. The steep grade is designed to discourage truck traffic from using Harriman Road.

Although erosion control devices were in place according to the original design, topography dictated about an 80-feet cut in elevation. About 180,000-cubic yards of dirt cut from the hill was used as filler in the lower levels.

Thomas Williams of Thomas Williams Construction said the road should be finished in about a month, depending on the weather.

“We’re hoping to lay some asphalt within the next couple of weeks, at least on this front section (where it connects to Stone Lake Road). Then we’re going to try to do the same thing on the other end and work back toward the middle because the bulk of the dirt is here in the middle,” Williams said.

LIC South is needed to connect the proposed Spring Branch Industrial Park to APD 40 and Interstate 75. The $2 million road is funded 50 percent by TDOT, with both Cleveland and Bradley County funding $1 million each for the local share.

Tennessee Department of Transportation will build a new interchange across APD-40 about halfway between Exit 20 and South Lee Highway. LIC North will connect the new interchange to the northeast quadrant of Exit 20 and I-75.

The Cleveland City Council and Bradley County Commission approved naming LIC North and LIC South, “Cherokee Gateway.”
