M27 Motorway Closure for New Junction Construction: Diversions, Delays, and What Tourists Need to Know

As of December 24, the M27 motorway in Hampshire is closed in both directions to allow for a significant infrastructure project. The closure is part of a collaboration between National Highways and Hampshire County Council to create a new junction for the £100 million Welborne Garden Village development. This project, aimed at improving local transport, will see the construction of 6,000 new homes.

With the M27 closed between junction 9 (Whiteley) and junction 11 (Fareham), motorists are facing considerable disruptions during the festive period. The closure is expected to last for two weeks, reopening on January 4, 2026. The diversion routes and the project’s impact on travel are already causing concern for locals, tourists, and business travelers alike.

Which Part of the M27 Is Closed?

The section of the M27 impacted by the closure runs from junction 11, which serves Fareham, to junction 9, which serves Whiteley. This stretch of motorway is a key route for both local commuters and tourists heading towards popular destinations in Hampshire.

Though the rest of the M27 will continue to operate normally throughout the holiday period, other roadworks are still in place elsewhere on the motorway, meaning that travelers will need to remain vigilant for potential delays. The closure on this stretch is particularly significant due to the ongoing work to build an underpass for the new junction, which will form an essential part of the Welborne Garden Village development.

Why Is the M27 Closed?

The closure is required to move an 8,500-tonne underpass into position, a crucial step in the creation of the new junction that will serve the massive Welborne Garden Village project. The village, which will feature 6,000 homes once completed, is expected to significantly transform the local area and improve connectivity for future residents and visitors. However, the scale of this project means significant disruption for current travelers, especially during the busy Christmas and New Year period.

The new junction will involve the construction of a dual carriageway with four roundabouts, designed to create a smoother, “free-flowing link” between the motorway and local roads. While these improvements are vital for future development, they are causing a major inconvenience for those traveling during the closure.

How Long Will the M27 Stay Closed?

The M27 closure began on the morning of December 24, 2025, and is expected to last for two weeks, with the motorway reopening at 4:00 AM on January 4, 2026. This timeline is subject to change, depending on how quickly the underpass can be positioned and the work progresses.

This long closure period coincides with one of the busiest travel times of the year, adding pressure to holiday travel plans. National Highways has emphasized the importance of allowing extra travel time during this period, as drivers will be diverted onto alternative routes.

What Is the Diversion Route?

Motorists traveling between junction 9 (Whiteley) and junction 11 (Fareham) will need to follow a diversion route, which is expected to take approximately 15 minutes longer than the usual journey. The diversion takes drivers along the A27, a stretch of road that runs through Segensworth, Titchfield, and Fareham, before reaching junction 11.

The total length of the diversion is 5.9 miles, which is significantly longer than the normal motorway route. However, it is important to note that the diversion could take even longer due to the increased volume of traffic on this alternative route. Drivers are advised to factor in at least 30 extra minutes to their journey to account for potential delays.

For tourists and travelers, this diversion could add significant time to travel plans, particularly if they are heading to or from the Southampton area or other destinations near Fareham and Whiteley.

Impact on Business and Tourism Travel

The M27 closure is particularly disruptive for business travelers who rely on this route to access various business hubs in Hampshire. The delays on the diversion route will affect not just local commuters but also travelers attending business meetings or conferences. The diversion could cause delays, particularly if traveling during peak times or if unfamiliar with the alternative roads.

For tourists visiting Hampshire, including attractions in Southampton and the New Forest, the road closure is likely to lead to longer travel times. Those planning to visit popular spots like the historic city of Winchester or the nearby coast should also prepare for disruptions. Visitors planning to take public transport or rent vehicles will likely encounter additional delays and should adjust their plans accordingly.

Key Points to Remember:

• M27 Closure: The M27 is closed between junctions 9 (Whiteley) and 11 (Fareham) for two weeks from December 24, 2025, to January 4, 2026.
• Diversion Route: Drivers will be diverted along the A27, a 5.9-mile route that runs through Segensworth, Titchfield, and Fareham, adding 15 minutes or more to the normal journey time.
• Allow Extra Time: Motorists are advised to plan for at least an extra 30 minutes due to the increase in traffic on the diversion route.
• Impact on Travel: The closure will affect both business travelers and tourists, especially during the busy holiday period.
• Reopening Date: The M27 is expected to reopen at 4:00 AM on January 4, 2026, although this is subject to change based on the progress of the works.

Travel Tips for Tourists and Commuters:

1. Plan Extra Time: If you’re traveling through Hampshire, especially between Fareham and Whiteley, be sure to leave extra time for your journey. Allow an additional 30 minutes or more for potential delays.
2. Use Public Transport: If possible, consider using public transport options to avoid the traffic disruptions caused by the diversion. Train and bus services may offer a more reliable option during this time.
3. Check for Updates: Stay updated on the progress of the roadworks and diversion routes by checking official government websites like National Highways and Hampshire County Council for the latest travel information.
4. Avoid Peak Travel Times: Try to avoid traveling during peak times, such as early mornings and late afternoons, when traffic congestion on the diversion route is likely to be at its worst.
5. Alternative Routes: If you’re familiar with the area, consider using alternative routes to bypass the diversion completely, especially if you’re heading to destinations like Southampton or Winchester.

Conclusion: Navigating the M27 Closure This Holiday Season

The M27 closure is a major disruption for both residents and visitors during the holiday season. While the roadworks are crucial for future development in the Welborne Garden Village area, the immediate impact is felt by those relying on the M27 for travel. Tourists, commuters, and business travelers should plan ahead to navigate the road closures and diversions, ensuring they have ample time to reach their destinations.

As the project progresses, National Highways and local authorities will continue to provide updates. Travelers are urged to stay informed and adjust their plans accordingly to avoid unnecessary delays during this busy period.
