A look at the entrance of the Callahan Tunnel where construction workers have been ahead of schedule on the March 12 re-opening date.

With the Callahan Tunnel Rehabilitation Project run­ning a bit ahead of schedule, we were given the opportu­nity to walk the tunnel on Wednesday as construction work took place. The sched­uled re-opening date remains March 12th, but MassDOT executives appeared optimis­tic that incentives for con­tractor McCourt could mean an earlier opening to traffic. Work started at both ends, at North Street in the North End and on the other side of Boston. Crews are working toward the middle using hy­dro-based machinery to blast off the foundation down to the steel rails so the flooring can be replaced with new concrete. The sides of the tunnel are also undergoing rehab so that a new bracket structure can be installed for the panels that will help brighten the interior space.

A direct hotline to the con­tractor has been established to resolve problems, such as noise. The contractor is try­ing to limit loud noise in the overnight hours, but they con­cede that has not always been possible. A “tunnel door” will also soon be in place at the entrance. In addition to reduc­ing noise, the door will allow for heating when the concrete floor is poured. Temperatures were well below freezing on Wednesday afternoon when this video and photos were taken, but it was almost 40 de­grees inside the tunnel.
