Construction of the Bluffton Parkway flyover, which will link the road to U.S. 278, will require overnight lane closures in early and mid-January.
Contractor R.R. Dawson Bridge Co. is scheduled to widen U.S. 278 at the western end of the bridges to Hilton Head Island beginning Jan. 6 to allow for lane shifts while the company builds the flyover and ramps connecting to the highway.
The first closures will be between 8 p.m. and 6 a.m. Jan. 6-10, to place new asphalt to widen the highway between the bridges and Buckingham Plantation Drive.
A second week of closures will be between 8 p.m. and 6 a.m. Jan. 13-17, to install temporary concrete barriers and place new pavement markings for lane shifts in the area.
Those lane shifts will be begin when the concrete barriers are in place and will last until the project is completed, expected to be in October 2015.
Drivers should pay attention to construction signs and be aware of the roadside equipment and crews. Delays are expected.
Last week, county officials announced changes to the flyover's construction and additional utility relocation would cost the project an extra $750,000, which will be covered by the project's $4 million contingency fund.
The project's construction plan is designed to cause minimal traffic disruptions during the day, county engineering director Rob McFee has said. Crews will piece together the portion of the flyover that will pass over U.S. 278 at night, leaving all four lanes of the highway open during daytime hours.
