This cool aerial photo of ATL brought a question to my mind that perhaps the experts on a.net can answer:
Why are the taxiways between runways 26L and 26R, and to the north of 26R, not aligned straight with the runways? Instead, they jog over near the ends of the runways.
If I recall, the old terminal at ATL used to be to the north (right side) of the picture, so perhaps that explain the northernmost taxiway, but what I've observed at most other airports with closely-spaced parallel runways is that the taxiways follow the same straight path as the runways.

Quoting N774UA (Reply 1): My guess would be that it has something to do with the ILS sensitive area.
That was one of the possible answers I though of, but then I notice that the middle taxiway actually cuts over closer to the approach area of runway 26R, which is the primary landing runway (evidenced by the skid marks) on the north side of the ATL complex. If it gets closer to the runway at the approach end, I would think it more likely that it would interfere with the ILS sensitive area.

Actually, it would interfere with the ILS components. Look to the right of the 1000' markings on both 26L and 26R. See the grey, circular areas with the small white box in each of them? Those are the glideslope antennae. The taxiways have to be routed around those antennae.

One other thing to consider is that the runways in ATL used to intersect and that the taxiways (more evident on the south side of the field) use some of the original runways. It looks more like the ILS issue on the northern side but might have a little to do with original placement of runways.
