One lane in both the east and westbound directions along a stretch of U.S. 278 near the Bluffton Parkway flyover will close Sept. 30 at 7 p.m. and reopen the following morning at 6 a.m.
The lanes will be closed between Buckingham Plantation Drive and the bridges to Hilton Head Island, according to a news release from construction firm R.R. Dawson Bridge Company.
The closure will allow crews to install signs along U.S. 278, the release said.
Drivers traveling in the area are asked to reduce speed and be aware of crews and equipment.
