Just in time for the Monday morning commute, Boston’s Callahan Tunnel, which carries traffic from downtown Boston to East Boston and Logan Airport, will reopen several days ahead of schedule.

Commuters can expect the tunnel to be open to traffic by 5 a.m. Monday morning.

The Callahan Tunnel has been closed since January for a complete rehabilitation on the 52-year-old structure. The $25 million overhaul includes work to the tunnel’s deck, curb line, gutters and replacement of the tunnel’s wall panels.

Contractors working on the project have been at it all weekend paving the tunnel, installing lane markings and working with MassDOT to remove barriers and detours currently in place in advance of the opening.

It’s going to take a week to return traffic to where it was pre-closure. Below is a list from MassDOT with details, including the closure of Exit 24/Government Center on I-93 Southbound Sunday night into Monday morning. Additionally, I-93 Southbound through Boston will be closed completely overnight Tuesday into Wednesday.

  • Sunday night, March 9 from 11 p.m. until Monday morning March 10 at 5 a.m., Exit 24 off of I-93 Southbound, which carries traffic to Government Center, will be closed to allow crews to remove barriers, install lane markings and prepare to open the Callahan Tunnel.
  • On Monday morning, March 10, digital message boards along the highway will display that the Callahan Tunnel is open.

  • Large detour signage will be removed Sunday/Monday March 10 and the remainder through March 12.

  • A complete closure of I-93 Southbound through Boston overnight Tuesday, March 11at 11 p.m. into Wednesday, March 12 at 5 a.m. for the removal of overhead detour signage.

  • Police detail posts supporting the detour routes will end by Wednesday, March 12.

  • On Wednesday morning March 12, the Commercial Vehicle Only restrictions and HOV lane 2+ restrictions and will once again take effect on the South Boston Bypass Haul Road and the HOV Express Lanes to the Airport.

  • The I-93 Southeast Expressway HOV Zipper Lane’s early 2 p.m. Southbound opening will continue through Friday, March 14, but return to a 3 p.m. opening on Monday, March 17.

  • Traffic cameras that helped officials monitor detour route conditions and messages boards will be removed.

The rehabilitation project allows for single-lane restrictions and complete overnight closures in the months ahead, according to MassDOT. The detour during those overnight closures will be posted as needed and direct motorists along surface streets and into the Ted Williams Tunnel.
