While the road is about to be temporarily diverted so the Dart cut and cover tunnel can be dug out there are no signs yet for the same to happen to the taxiway. When the exiting road was put in way back in 1999 it was a massive job as the taxiway had to be moved out of the way and then put back. Still wondering if they might tunnel under the taxiway.
The M1 bound A1081 has been reduced to a single lane for the Dart Gateway bridge work which is causing tailbacks from the airport. The road will remain a single lane for around a year.
The opening date for the Dart is the Autumn of 2021, which hasn’t changed despite the project starting 6 months late. As most airport projects overrun I am thinking it was open in 2022.
