In that case, route the crosstown G line into the 63rd street tunnel. Let a new Metropolitan Ave/Union Tpke line share the G connection--maybe a widened section of the G line with express tracks--from Metropolitan Avenue up to the tunnel.
Or, as the L train tube at 14th street probably has extra capacity, route my new Queens line into Manhattan that way. But extending the Houston line east might spur economic development on the far east side.
The city's government doesn't seem able to cope with funding mass transit development. I don't know why--it's a very wealthy city.
