The incident created many questions, and the Atlanta Journal-Constitution will strive to answer them Friday (and beyond).

Here are the questions we’ll tackle first:  

1. Who is to blame for the fire?

2. Why couldn't GDOT come up with a comprehensive commuting plan Thursday night so that commuters would know their options?

3. Why did DeKalb County school officials decide to cancel all classes when only a small portion of the county was affected by the bridge fire?

4. What is the impact on nearby businesses and offices?
