Highway 3 connecting Helsinki and Tampere faces a full overnight closure for essential tunnel maintenance. The shutdown affects traffic in both directions at the Hämeenlinna tunnel section. Road authorities confirm the closure began Thursday at 10 PM and continues until Friday morning at 5 AM.
Maintenance crews are performing thorough cleaning and repair work on the tunnel tubes. Workers will address one tunnel tube at a time during the overnight hours. This systematic approach minimizes disruption while ensuring proper maintenance.
Traffic officials have established detour routes around the closed tunnel sections. Drivers should follow posted signage for alternative paths. The tunnel will reopen immediately after completion of all maintenance activities.
Finland's highway maintenance system prioritizes overnight work to reduce daytime traffic impacts. The country's extensive tunnel network requires regular cleaning and safety inspections. These preventive measures help maintain structural integrity and driving safety.
