For now all the coaches, buses and the train shuttle bus have to go the long way around the CTA and then queue to pass the exit barriers not that there is much of a queue. The animated video the airport produced a couple of years ago showed a coach short cut that crossed the duel carriageway from the bus station. This short cut is going in but how practical it will be for a double length articulated shuttle bus to cross a dual carriageway remains to be seen.

Oh and yesterday within 10 minutes of the new temporary route opening there was an accident when a car went into the back of the car in front.
Now is the right time to do this major project but Easter is not far away so we will have to wait and see if the work is finished regarding the building of the missing section of the inbound duel carriageway.
