Q: Does GDOT use a gravel and sand mix on roads during icy weather instead of the calcium chloride mix favored in Northern states? After a snow event, the cars here are not all white from the “salt” on the roads. What is the difference and why isn’t traditional road salt applied?
— Mark McCormack, Cumming
A: The Georgia Department of Transportation uses a mixture that consists of four parts of stone to one part salt in warmer weather, spokeswoman Natalie Dale told Q&A on the News in an email. GDOT adds 100 pounds of calcium chloride to each truckload of stone/salt mixture when the temperature falls below 25 degrees. She wrote that the GDOT also pretreated bridges and overpasses on area interstates with a brine mixture before the winter storm hit metro Atlanta on Jan. 28.
Q: I was wondering how much a 30-second TV commercial spot cost for Super Bowl I. What was the average player salary that year? What network televised that game?
— Lance DeLoach, Thomaston
A: A 30-second commercial cost $40,000 in Super Bowl I, which was played on Jan. 15, 1967. By comparison, 30-second ad spots cost around $4 million each for Super Bowl XLVIII on Feb. 2. The Green Bay Packers, the NFL champions, defeated the Kansas City Chiefs, who were the AFL champs, 35-10 in Super Bowl I. CBS and NBC each broadcast the game because NBC held the rights to AFL and CBS had NFL rights, and each network used its own announcers for the Super Bowl. The average salary was $25,000 in 1967, according to "The Business of Professional Sports."
