In the 1960s, when Interstate I-75/85 was built through the heart of Atlanta, it wiped out whole neighborhoods. To this day, people living in its shadow deal with all kinds of ill effects: high air pollution, traffic, reduced mobility.

Now the state of Georgia is looking to reduce congestion on the corridor, saying “no idea is off the table.” But some ideas should be discarded right off the bat — like the notion that adding space for cars is going to solve the traffic problem.

Darin Givens at ThreadATL warns that the state’s approach might compound past mistakes. Or it could try something new — something that might actually work:

Some have suggested increasing capacity through a tunnel or a double-deck expansion. But doing that while leaving all the exits open means more car trips (induced demand) that create more exhaust and bring more vehicles into the city, all of them needing parking spaces.

And leaving things as they are means we continue with the current level of exhaust which is harmful to our health. Nothing happens in a bubble. Transportation decisions at the state level affect urban livability in the city.

Could we put Bus Rapid Transit lanes on all freeways in Atlanta and put BRT stations throughout the metro? And encourage transit-oriented development around those stations? It’s just a random thought, but it’s an example of the kind of regional-scale “fix” for congestion that would actually accomplish something, rather than trying to make the road design bear the weight of solution as the built environment all around it remains car-centric and lacking in transportation options.
