Attention motorists! Expect lane closures and a reduced speed limit on US 17 through Restaurant Row. Traffic control devices are being installed today and tomorrow, with work beginning this week on the fifth and final phase of a 36-inch sewer force main replacement beneath US 17. Drivers can expect lane closures on the two inside, southbound lanes of US 17, plus the median, from Chestnut Road on the project's northern end to the US 17/Kings Hwy. split on its southern end. Speed limits through the construction zone have been lowered to 35 miles per hour. Northbound traffic lanes are not affected, although the speed limit is reduced for northbound traffic on US 17, too. These lane closures will be in place around-the-clock during the 1.1 mile, $2.9 million project, which is expected to be complete in 90 days. Much of the work will occur at night, Monday through Friday, although the South Carolina DOT has approved 24-hour construction, hence the 24-hour lane closures and speed limit reduction. The new 36-inch sewer line replaces a 30-inch line that is 30 years old. Ruby Collins, Inc., of Smyrna, Georgia, is the contractor.
