A: This is part of the sign upgrades as Hartsfield-Jackson International Airport prepares for the opening of the new Maynard H. Jackson Jr. International Terminal. Georgia DOT spokesman Mark D. McKinnon told Q&A on the News that the signs will inform drivers that international travelers should access the airport via I-75 and C.W. Grant Parkway, while domestic travelers should still use I-85 and Camp Creek Parkway. "Some of the new signs are up and are covered because we don't want to send international travelers to the terminal that isn't opened yet," he said in an email.

Q: For the past several years, there has been a frequent commercial during the Australian Open that features people looking into a mirror and seeing other images. The music accompanying the ad is beautiful. Can you find out if it was written for the commercial or any info about it?

"A Heart Divided" is on "A Loud Call," an album recorded in Nashville, Tenn., and released in July 2008. The song and the album are available on iTunes.
