The work definitely started at least 3 months late, I am thinking it was actually 6 months late. Work is started in the order of complexity and time to achieve completion. The route through the midterm car park involves no cut and cover tunnel but a trough. Remember that part of the tunnel inside the CTA has not even been started yet and the route across Taxiway Bravo is only now being piled with sheeting. I find it hard to believe that the trough will be the last piece of the jigsaw to be completed and will delay the project.
This is the original time line and shows project dates although I have cut off the year and shows it as a 4 year 9 month project that was meant to have started in May 2018 after enabling work. It never did and was late summer before it was started. The time line shows an opening date of April 2021, it then became the summer of 2021 and now it is the Autumn.
Orange is the trough
