A couple of props:*
Actual opening date:
On or before July 14, 2028: +2000
July 15, 2028-January 1, 2031: +675
January 2, 2031-January 1, 2034: +180
On or after January 2, 2034: -450
Abandoned /scrapped at any point: +300
(The United States no longer existing at that point would likely factor heavily into an abandonment.)
Actual cost:
<$12bn: +5000
$12bn-$20bn: +475
$21bn-$30bn: +200
>$30bn: -1800
