The I-75/85 Connector through Atlanta is clogged with traffic. There are a number of alternatives to deal with it. Some suggestions:

1. The proposed western connector starting at Cartersville and I-75 passing through Paulding County and connecting to I-75 somewhere from Griffin to further south.

2. An eastern connector off I-85 in Gwinnet County.

3. Separating 75 and 85 using a separate path west of Northside Drive and Ft. McPherson and the Langford Parkway.

4. The proposed east side extension of 675 to 400 using about 7 miles of tunnels under Inman Park and Druid Hills.

5. Express lanes either by widening or double decking the connector.

6. Combinations of 1-5 above.

7. Do nothing on the road but do mass transit rail improvements.

8. Close the connector and force through traffic onto 285 (presumably with mass transit rail improvements).

9. Do nothing at all. We can deal with a little congestion.

Thoughts?

I'm all for 4 and 7, maybe even 1 (though I'm thinking that may cause more sprawl?)

Need to address the 75/85 interchange with I-20.. one lane to exit east and one for west with the HOV lane having no exit. This causes way too much of the backup through downtown. Oh and the edgewood on ramp crossing through all that merge over makes a mess.

Staying on topic I think there should be some alternative "limited access" routes around the ATL. With the late reaction to this 20 year old problem I am not sure there are many options to go around so this puts coming straight through existing corridor with double deck or tunnels. Going through the outer areas adds extra drive time and does not make sense except for the peak drive times.Not very cost effective.

I prefer #3 and #1.

A western connector doesn't really doesn't have to add many miles to I-75 since I-75 bends in Atlanta. So it does more than an eastern connector. The original proposal was going to be in more rural areas, but those counties didn't want it. The supporters were going to talk to Douglas, Fulton, Fayette and Spalding Counties. Those areas are already developed so it could not only handle through traffic, but it could handle suburb to suburb traffic and encourage fill in development instead of ex-urban development like the original proposal. They already are talking about relocating and widening highway 92 in the area. This could be an alternative.

As I said on the other discussion, I like the idea of undoing Atlanta's biggest mistake, combining 75 and 85. Have 85 continue north of Atlantic Station through undeveloped and underdeveloped predominately light industrial areas west of Northside Drive. The new road (would have to be toll) would use the western edge of Ft. McPherson and then head out Langford Expressway to 285 where it would meet the existing 85. This would provide an alternative to the current connector, could be used as HOT lanes to include high occupancy vehicles, ease pressure on the current I-85 improving access to the airport, and possibly even share ROW with a Cobb Co. MARTA extension for part of its length. Because of its many benefits, if I had to choose between this and the western connector, I would choose this. Not sure which would be more expensive as the other would be many more miles, but be in lower cost areas.

Double decking is expensive, although you avoid new ROW. Its also not particularly pleasing aesthetically. If you are going to add ROW, I would prefer the benefits of a new road to continuing the existing merged mess as in alternative 5.

5a (as suggested by StAubin) Express lanes using existing lanes in
the connector

6. Combinations of 1-5 above.

7. Do nothing on the road but do mass transit rail improvements.

8. Close the connector and force through traffic onto 285 (presumably with mass transit rail improvements).

9. Do nothing at all. We can deal with a little congestion.

Revised including StAubin's suggestion

1 and 7. Although I'd support rebuilding the Connector/20 interchange if there is something feasible that can be done. The atrocious lack of capacity is responsible for major delays for people who live south, west, and east of town. I hate to say it, but the interchange is oriented to giving a lot of people the option of getting to south downtown easily, but most people are just trying to get on the connector to go to north downtown, Midtown, or Buckhead.

But my general feeling is that extending MARTA (or some form of mass transit) into (1) Cumberland (2) Clayton County and (3) to 285 on the west side would be far more cost effective and better long-term. MARTA could easily double its capacity alongside the connector. Easily. The issue is that for commuters from the northwest, west, and south sides, it's just not very user-friendly, and they have to jump through great hoops to use it.

Today was a perfect example of the need for another road alternative to the connector. Due to road construction near the airport, traffic southbound was at a virtual dead stop for 2 miles across all lanes-at 1:30 in the morning! Northbound there was an accident at 17th that shut the freeway. Everyone was forced onto I-20. Wasn't too inconvenient for me (although I had to take an exit I'm a little nervous taking even during the daytime), but for a lot of people it was.

Not an accident ... it seems the bridge is falling apart:
