Allow me to chime in with regards to the diagonal runway alternative from the 2020 project:
1. 2 new runways (11L-29R and 11R-27L) would be built southwest and northeast of the existing terminals.
2. Terminals B through F would be replaced with a tier-concourse arrangement similar to ATL
as well as what MWAA is proposing at IAD
. These new terminals would be connected be an underground APM system; again, similar to ATL
3. Runway 8-26 would be demoted to a taxiway. I'm not clear as towards whether Runway 17-35, 9L
-27R and/or 9R
-27L would survive or be demoted to taxiways. This wouldn't be the first time this happened; Taxiway D4 & E4
were, at one time Runway 4-22. Back then the old runway extended into the present commuter aircraft apron is.
In addition to tearing down the terminals, the main issue is the noise from the new runways over Delaware County; and we're not just talking Tinicum here. We're talking about Swarthmore, Springfield, Ridley Park, Wallingford, Nether Providence. Many of these towns are a little more wealthier than Tinicum and
have more political clout in Delaware County.
As I stated in an earlier thread a month ago. The public hearings turned out to be a PR
nightmare for DOA, FAA, and the DVRPC (Delaware Valley Regional Planning Commission) especially in reference to the diagonal runway proposal. There were several public meetings held throughout the Delaware Valley, however, not one
meeting was held in Delaware County, Pennsylvania (where the changes would impact the most). The closest meeting to them was held in Wilmington, Delaware (the state). Needless to say, many residents from the above-mentioned communities attended that meeting and let their thoughts be heard...rather loudly
In a nutshell, while the diagonal concept was thinking 'outside the box'; what's outside the box could be this concept's downfall.
By the way, the current Runway 9L
-27R and 9R
-27L are spaced 1400 feet apart; too close to conduct simultaneous landings which can contribute to flight delays.
Just my 2 cents.
