Christian Horner on Sunday said he "knows" the inaugural Korean grand prix will take place as scheduled in two weeks.
There has been great uncertainty about the health of the event due to delayed construction at Yeongam, but Bernie Ecclestone and some other bosses are now openly bullish.
Indeed, ahead of Charlie Whiting's inspection early this week, the latest photographs show that the top layer of asphalt is now laid, kerbs installed and the main grandstand complete, even though some supporting infrastructure is unlikely to be ready for late October.
Red Bull team boss Horner told German Sky television: "We know it is going to take place.
"It's interesting because it's new for everybody. We're looking forward to it.
"The long straights don't really suit us, but our car should work well on the twisty parts," added the Briton.
