Columbus Air Force Base officials say construction of a center runway is ahead of its projected late-August completion target.
The Commercial Dispatch reports the work began in March and officials say it is about two-thirds complete.
The $31.29-million project is the most extensive overhaul to the two-mile runway since it was built in 1959.
The 300-foot-wide runway's 10,000 foot-long asphalt section is being replaced with a 10-inch thick, 200-foot-wide concrete surface. Outside 50-foot-wide runway edges are being replaced with new asphalt.
Babcock Construction was awarded the contract in 2012 as the project's general contractor.
