A group of business and labor leaders calling themselves the "Tunnel + Transit Coalition" have made a video aimed at dissuading Mayor Mike McGinn from vetoing contracts to build the deep-bore tunnel, which the mayor has pledged to do by 3:00 p.m.:

Meanwhile, other folks are adding to the chorus: Don't veto! "While we respect your preferences for a different Viaduct replacement approach, this compromise [the tunnel] is the only feasible way to move forward," wrote 17 pro-tunnel folks who were involved in stakeholders process in a long letter to McGinn (.pdf). He met with 10 members of the group yesterday.

But right or wrong, there's no way he's going to roll over and play dead now.
