Callahan Tunnel Overnight Closure Scheduled for July 9-10, 2025

Key Takeaways

• Callahan Tunnel closes overnight July 9–10, 2025, for maintenance from 11 p.m. to 5 a.m.
• Sumner Tunnel closed fully July 5–August 5, 2024, extending travel times by up to 2 hours.
• Alternative transit like ferries, Logan Express, and MBTA Blue Line increased to ease tunnel closures.

Travelers and commuters heading to Boston Logan Airport face new overnight disruptions this week as the Callahan Tunnel, a main route connecting downtown Boston to the airport, closes for maintenance. The closure starts at 11 p.m. on July 9, 2025, and ends at 5 a.m. on July 10, 2025. Officials say this work is necessary to keep the tunnel safe and reliable, but it comes after a year of major tunnel shutdowns that have already tested the patience of travelers, airport workers, and local residents.

Immediate Impact: What Travelers Need to Know

The Callahan Tunnel closure will block all traffic from downtown Boston to Logan Airport overnight. Anyone planning to catch a late-night or early-morning flight, or picking up loved ones, should plan for extra travel time and consider alternate routes. The Massachusetts Department of Transportation (MassDOT) urges drivers to use the Ted Williams Tunnel or surface streets, but warns that these detours can cause heavy congestion, especially during busy travel periods.

“We know these closures are inconvenient, but they’re essential for keeping our infrastructure safe and reliable for everyone,” said Monica Tibbits-Nutt, MassDOT Transportation Secretary and CEO. “We’re working hard to minimize disruption and keep the public informed.”

Recent Tunnel Closures: A Year of Disruption

This latest closure follows a series of major shutdowns affecting access to Boston Logan Airport. The most significant was the Sumner Tunnel full closure from July 5 to August 5, 2024. This month-long shutdown was part of a $160 million restoration project to fix aging infrastructure in the nearly 90-year-old tunnel. The work included replacing the tunnel ceiling, repairing walls and roadways, upgrading lighting, and improving drainage to prevent flooding.

During the Sumner Tunnel closure, travelers faced detours that added up to 2 hours each way to airport commutes. The timing couldn’t have been worse: July is the busiest month for Logan Airport, with more than 52,000 flights scheduled. Many travelers missed flights or had to leave home hours earlier than usual.

Weekend Closures Continue

Even after the full closure ended, the Sumner Tunnel continued to close on weekends for finishing work. These weekend closures, running from 11:00 p.m. Friday to 5:00 a.m. Monday, are set to continue through November 15, 2024. While the main restoration finished ahead of schedule in October 2024, minor repairs and upgrades are still being completed during off-peak hours to avoid further major disruptions.

Long-Term Benefits: Safety and Resilience

Despite the frustration, officials say the Sumner Tunnel project will pay off for decades. The restoration is expected to extend the tunnel’s life by at least 75 years and make it safer and more resistant to climate-related problems like flooding. According to analysis by VisaVerge.com, the project also serves as a model for how to speed up big infrastructure repairs while keeping people moving.

“This investment means safer, more reliable travel for everyone using Logan Airport and the surrounding roadways,” said Jonathan Gulliver, State Highway Administrator. “We appreciate the public’s patience as we finish this important work.”

How Travelers Coped: Alternative Transportation Options

With both the Sumner and Callahan Tunnels affected, travelers have had to get creative. MassDOT and the Massachusetts Bay Transportation Authority (MBTA) worked together to offer more public transportation choices and discounts to ease the burden.

• Ferry Services:
  The East Boston Ferry ran for free during the Sumner Tunnel closure, giving travelers a way to skip traffic jams. New ferry routes from Lynn and Winthrop to Boston and Logan Airport were also introduced, with fares set at the MBTA Zone 1A rate ($2.40). These ferries helped many commuters avoid the worst delays.

• Logan Express:
  The popular Logan Express bus service offered a 25% discount for tickets bought online, and children under 17 rode free. This made it easier and cheaper for families to reach the airport without driving. Water transportation users also received a “Ticket to Skip,” allowing them to move faster through airport security.

• MBTA Blue Line:
  The MBTA increased service on the Blue Line subway, which connects downtown Boston to the airport. Trains ran at full speed, and extra staff helped guide travelers to the right stops.

“We wanted to make sure people still had good ways to get to Logan, even with the tunnels closed,” said Phillip Eng, MBTA General Manager. “By boosting ferry and train service, we helped thousands avoid long delays.”

Detours and Congestion: The Reality for Drivers

For those who had to drive, the closures meant long waits and confusing detours. The main alternative, the Ted Williams Tunnel, quickly became crowded, especially during rush hour and weekends. Surface streets through East Boston and surrounding neighborhoods also saw heavy traffic, with some drivers reporting delays of more than two hours.

MassDOT strongly encouraged everyone to use public transportation if possible, both to reduce their own stress and to help keep traffic moving for emergency vehicles and airport workers.

Background: Why the Tunnels Needed Work

Both the Sumner and Callahan Tunnels are vital links between downtown Boston and Logan Airport. Built nearly a century ago, these tunnels carry thousands of cars, buses, and trucks every day. Over time, water leaks, crumbling concrete, and outdated systems made repairs urgent.

The Sumner Tunnel Restoration Project began in April 2022. Crews removed 3,800 ceiling panels, installed new arch segments, rebuilt over 13,500 square yards of roadway, and upgraded lighting and drainage. The project was originally expected to require two months of full closure in 2024, but thanks to efficient planning and hard work, the main shutdown was cut to one month.

“We knew this project would be tough on everyone, but waiting any longer would have put drivers at risk,” said Tibbits-Nutt. “We’re proud to have finished ahead of schedule.”

Community Response: Frustration and Understanding

Not surprisingly, the closures caused headaches for many. Travelers worried about missing flights, airport workers faced longer commutes, and local residents dealt with more cars on their streets. Some businesses near the tunnels saw fewer customers as people avoided the area.

Still, most people recognized that the repairs were necessary. “It’s been a pain, but I’d rather deal with traffic now than have the tunnel fall apart later,” said one East Boston resident.

Transportation experts say the project shows how cities can handle big repairs while keeping people moving. By offering more public transportation and clear information, officials helped reduce the worst impacts.

Looking Ahead: What’s Next for Logan Airport Access

As of July 2025, no more full closures of the Sumner Tunnel are planned. Any remaining work will happen during off-peak hours, with the tunnel open for normal use most of the time. However, periodic overnight or weekend closures of other tunnels, like the Callahan Tunnel, may continue for routine maintenance.

MassDOT promises to announce any future closures well in advance and to keep working with the MBTA and Massport to offer alternatives. Travelers are urged to check official sources before heading to the airport, especially if traveling late at night or early in the morning.

Practical Tips for Travelers and Commuters

If you need to reach Boston Logan Airport during a tunnel closure, here are some steps to make your trip smoother:

• Check for Updates:
  Always look at official websites like MassDOT and Massport before you travel. They post the latest closure times, detour maps, and public transportation options.

• Use Public Transportation:
  The MBTA Blue Line, Logan Express buses, and ferries are often the fastest ways to reach the airport during closures. These services are usually increased during major shutdowns.

• Plan for Extra Time:
  Even with the best planning, detours and crowded trains or buses can add time to your trip. Leave home earlier than usual, especially if you have a flight to catch.

• Consider Alternative Routes:
  If you must drive, use the Ted Williams Tunnel or follow posted detour signs. Be ready for heavy traffic and possible delays.

• Look for Discounts:
  During major closures, discounts on Logan Express and free or reduced ferry fares may be available. Check online before you buy tickets.

• Stay Informed:
  Sign up for email or text alerts from MassDOT or Massport to get real-time updates about closures and traffic conditions.

Implications for Different Groups

• Travelers:
  The closures mean travelers must plan ahead and allow extra time, especially for early or late flights. Missing a flight can be costly and stressful, so using public transportation or leaving early is wise.

• Airport Workers:
  Many Logan Airport employees rely on the tunnels to get to work. Longer commutes can affect shift schedules and family life. The extra ferry and train options help, but some workers still face longer days.

• Local Residents:
  People living near the detour routes see more traffic and noise during closures. Some worry about emergency vehicle access and parking. MassDOT has tried to limit these impacts by scheduling work at night and on weekends.

• Businesses:
  Shops and restaurants near the tunnels may lose customers during closures, while others, like ferry operators, see more business. The long-term improvements should help everyone by making travel safer and more reliable.

Expert Perspectives: Lessons Learned

Transportation analysts say the Sumner Tunnel project is a good example of how to handle big repairs in busy cities. By speeding up the work, offering more public transportation, and keeping people informed, officials reduced the pain for everyone involved.
