Also the construction labor itself adds many benefits to the area. In addition, in the longer run, the costs are recovered with revenues from new buildings and amenities built near or on top of these tunnels. In addition, when one looks to the future of increasing use of electric cars and less polluting vehicles, the problems of providing clean air in these tunnels is lessoned. And, if one used a mix of open and closed on the connector, this might not be such a problem at all.

keep in mind i'm specifically talking about *tunnelling* the connector; not just capping it like others have mentioned. this way, a new street grid could be established where the connector was, and potentially could support high rise buildings on top.
