Hartsfield-Jackson International Airport is resuming roadwork for the construction of massive canopies over the curbside roadways outside the domestic terminal — and that means lane closures.

The Atlanta airport put the roadwork on hold during the holidays but has since resumed the work.

Motorists should allow extra time to pick up or drop off passengers, and should watch for police officers and signs indicating which lanes are closed on the airport roads.

From now until May 25, Terminal South will have one outer lane closed and one lower-level lane closed, according to Hartsfield-Jackson.

During the same period, Terminal North will have one outer lane closed and parts of the lower roadway sidewalk and bus lane closed.

Parking garage access lanes won’t be affected, the airport says.

The canopies are one of the most visible elements of the airport’s long-term expansion and modernization project. They will cost around $125 million to construct, and will be 55 feet high and 865 feet long. The aim is to protect travelers from the elements and create a dramatic entrance to the airport.

To build the canopies, the airport will have to relocate some utility infrastructure and build piers deep into the ground to support the steel frame.
