SOP!!
This is nothing new...in fact, we have a similar issue here in Northern Virginia on the western leg of the DC area subway...This 8 mile stretch of *ABOVE GROUND* metro system with 5 stations ending at Dulles Airport is climbing to over 5 billion dollars....It's already almost a year behind schedule and 2 billion dollars above estimates....People are saying that by the time this thing is built, it will have cost double the initial estimate and fulfill the needs of fewer than 30 % of the original users,. and with maintenance and decreased ridership, it is estimated that this fiasco will *NEVER* break even...Kinda wonder what's the point...
