Project timelines and budgets for projects of that size have never been predictable. Look at software development, the industry has largely moved away from trying to predict large projects and now just builds the smallest increments possible. Building infrastructure in a city with 100,000 unknowns underground is far worse. Seattle had the same hand wringing around our newish rail line back in the early 2000s, now no one even knows it was late. Also - Now that Seattle is around 85% vaccinated, offices are re-opening and the trains are full again. London is being more conservative in their approach to reopening, but they are merely months behind.
