The latest evidence of the already wrong forecast just came in on an HKEJ story entitled “HZMB usage forecast is revised lower” on June 19 2018. Not surprisingly, a new 2016 consultant’s report lowered the projected automotive and foot traffic by a further 12% and 26% respectively! Below is an updated chart to illustrate the ever falling economic benefit of this grand civil engineering project… the red area represents the difference between the 2008 and 2016 forecasts.
