I suspect the express decision was made late enough in the project that converting the upper level probably required the least demolition. Adding island platforms would have required reconfiguring and demolishing tunnel walls and supports, which would be a tricky proposition because they had to support the el. Not impossible, but elevating the express tracks compares favorably cost-wise and time-wise against more complex options if significant amounts of the tunnel structure had already been built. |
