Steel girders are being installed above S.C. 707 to build the Carolina Bays Parkway bridge, which means temporary nighttime road closures through next week.
Road closures on S.C. 707 began Wednesday night at 20 minute intervals between 11 p.m. and 5 a.m. to move the girders into place, and will continue every night except Friday and Saturday.
Weather permitting, the structure should be in place by May 19, according to Horry County. Until then, motorists are encouraged to U.S. 17 Bypass as an alternative route.
“When that much steel is moving above, the reason for closures is safety concerns,” said Lisa Bourcier, Horry County spokeswoman.

“We did the same thing with the backgate intersection, but it was delayed twice because of weather, so we will have to see what happens,” Bourcier said.
Construction of the parkway and S.C. 707 are coordinated for completion at the same time in late 2017 or early 2018.
That’s taking into account an anticipated six month delay due to weather and relocation of utilities, Bourcier said.
The expected cost of the parkway, S.C. 31, is $225 million to $237 million, while the price tag for S.C. 707 is more than $100 million.
A portion of Enterprise Road that was closed for nine months as part of S.C. 31 construction will reopen next month, Bourcier said.
