The blue line shows the course of the DART across the taxiway. The red arrows show the 4 taxiway diversion points that were used when the road runnel was built in two halves. Seems the airport will have a lot less space to play with when the existing taxiway is dug up. I am thinking that contractors can only move the taxiway temporarily south due to the existing road tunnel and the location of the multi-story.
