Yes. There are lots of people like me who follow this second-hand.His, those posts about the sawtooth bridge were informative and helpful.
I was interested to note that one part of the project might be able to use the spoil from another part as fill. We did that in Edmonton for the 1983 extension of the LRT subway. Spoil from the tunnel boring machine was loaded into dump cars and pulled out in the night by Locomotive 2001, formerly of the BC Electric, and originally with the Oregon Electric. It was used as fill for the new yard. We saved many dump truck trips through downtown.
