Alert! Three major events Thursday should combine for a big old stew of going nowhere for Atlanta commuters near Midtown and downtown, according to Georgia Tech officials. This triple-whammy of gridlock terror is expected to compound the city's already horrendous late-week traffic, and it includes: 1. 65,000 predicted fans attending the Falcons' last preseason game at the Georgia Dome (7 p.m.) 2. The Georgia Tech Yellow Jackets' season-opening beatdown of Alcorn State (7:30 p.m.) 3. Lastly, Vice President Joe Biden and his motorcade are expected to travel The Connector around that time for a speech (also 7:30 p.m.) at the Ahavath Achim Synagogue in Buckhead. Consider yourself warned.
