It's crazy to have exit ramps in the middle of a road. Even in GTAuron's example junction, the exit ramps are on the outside. You can see just by looking at his render how how messy it is to have walls in the road and cutouts under the passing lane. There's also the issue that we'll have a 4 lane freeway exiting onto one lane in either direction, causing a bottleneck. It's difficult to understand OrC's plan, but it looks even more overcomplicated and unrealistic.
If you (OrC and GTAuron) have MSN Messenger or a compatible IM client, I'd like to talk through the pros and cons of the different sunken junction designs. I've got mIRC if you prefer that, but I've forgotten how to use it!
Has anyone found a location where any sunken junction will fit? Maybe somewhere between the two illSUB bridge junctions?
New Option: Link with Snow Racer's Tunnel
Here's some good news:
|QUOTE (Cerbera and Snow Racer)|
|[21:00:44] Cerbera/Ben: oh, will you be making that tunnel from illCOM to illURB after all?|
[21:02:47] SR (Alan): yes
[21:04:03] Cerbera/Ben: how many lanes will it have?
[21:04:17] SR (Alan): well
[21:04:18] SR (Alan): 2
[21:04:26] Cerbera/Ben: could you make it 4?
[21:04:43] SR (Alan): yes
[21:04:55] Cerbera/Ben: cool, that means Port Orchid (JasonB's island) could link into it after it has gone to illSTA
[21:05:17] Cerbera/Ben: nothing is confirmed yet, we are still thinking about how to link illSTA to illCOM
[21:05:20] Cerbera/Ben: but this gives us another option
New(ish) Option: Tunnel Exit on Unused Lot
It was suggested previously that we use an unused lot on illCOM for the link to illSTA. I've noticed that there's a suitable lot in the North, a couple of lots West from the bridge to illURB. The tunnel from Port Orchid would run past the north of illSTA, then would rise from the sea bed as it went under the North of illCOM. It would break onto the surface on the unused lot, and exit at a new junction on the illCOM 4-lane road.
JasonB doesn't want to take on a whole new lot, which makes sense since he already has so much on the go. However, if he builds the tunnel and the exit we could give the lot back to the MISA project for other people to fill with buildings, or parkland, or whatever.
The way I see it, we've got four options:
- Do a bridge over the Southern platform at Snow Racer's Marina.
- Develop the unused Northen lot for a tunnel to illSTA.
- Sink a length of the illCOM freeway to create a junction to a tunnel to illSTA.
- Link into Snow Racer's tunnel from illCOM to illURB using a tunnel from illSTA.
