Massachusetts Department of Transportation (MassDOT) officials gave a project update and underground tour of the Callahan Tunnel on Friday as the $25 million rehabilitation project draws to a close. The official re-opening date for the tunnel remains March 12th, but MassDot officials are hopeful it will be a bit earlier.

The primary work now completed is the replacement of the concrete deck floor for vehicle traffic. New side brackets have also been installed to avoid future mishaps of falling side panels. Once the tunnel is re-opened in early March, there will continue to be night closures to allow for additional rehabilitation work on the sides of the tunnels.

The Lieutenant William F. Callahan Jr. Tunnel, opened in 1961, is one of three tunnels beneath Boston Harbor carrying motor vehicles from the North End to Logan Airport and Route 1A in East Boston. It runs parallel to the Sumner Tunnel that opened in 1934. The Sumner Tunnel is expected to have a similar rehab project in 2016.

Photos from inside the Callahan Tunnel on Friday, February 28, 2014 are shown below. Compare these to the photos from early January during the demolition phase of the project.
