In a rare occurrence fueled by exceptionally cold temperatures, Estonian authorities have opened a 20-kilometer (12.5-mile) “ice road” across the frozen Baltic Sea, connecting the country’s two main islands of Saaremaa and Hiiumaa. The frozen passage was officially opened on Sunday, with eager residents forming a line of vehicles waiting to cross.

The decision to establish the ice route came after officials observed locals already attempting to drive across the frozen sea without proper safety measures in place. The improvised crossings began as ferry services struggled to maintain regular schedules due to sea ice following weeks of temperatures plummeting to minus 10 degrees Celsius (14 degrees Fahrenheit).

For the 9,000 residents of Hiiumaa, the smaller of the two islands, the ice road provides critical access to Saaremaa, home to 31,000 people. The crossing allows Hiiumaa residents to reach essential services including shopping facilities, schools, and cafes, as well as establishing a more direct connection to mainland Estonia.

Hergo Tasuja, mayor of Hiiumaa, emphasized the cultural significance of the ice road beyond its practical benefits. “For generations and generations, local people who live here, especially those who live near the sea, swim and use boats in the summertime,” Tasuja told The Associated Press. “And in winter, it’s in their blood to go to the sea” and venture out onto the ice.

The creation and maintenance of such ice roads require specialized expertise and constant vigilance. Marek Koppel, a road maintenance supervisor at Verston Eesti, the construction company managing the ice road, detailed the elaborate preparations involved. Workers must measure ice thickness every 100 meters (328 feet) to ensure at least 24 centimeters (9.5 inches) of solid ice, the minimum required for safe passage. The process includes smoothing over ice ridges and cracks, with constant monitoring of weather conditions and ice stability necessitating route adjustments as needed.

Strict safety protocols govern the use of the ice road. Vehicles cannot exceed 2.5 tons (5,500 pounds) in weight and must drive either below 20 kph (12.4 mph) or between 40 and 70 kph (25 and 43 mph). These specific speed restrictions prevent dangerous vibrations that could compromise ice integrity. Additional safety measures prohibit stopping, require adequate distance between vehicles, ban the use of seat belts, and mandate easily openable doors to facilitate rapid evacuation in case of emergency.

Alexei Ulyvanov, who traveled from Estonia’s capital Tallinn to experience the ice road with his children, reported favorable conditions. “The road was pretty good, it was easy to ride,” he said, noting he wanted to show his children “that it’s possible to ride a car over the sea.”

The phenomenon is increasingly rare due to warming winter temperatures across the Baltic region. According to Mayor Tasuja, this marks the first time in approximately eight years that conditions have allowed for an ice road between the two islands, highlighting the exceptional nature of this winter’s prolonged cold snap.

The successful implementation of this inter-island route has prompted authorities to commission Verston to establish two additional ice passages this week, connecting mainland Estonia to smaller offshore islands. These additional routes will further enhance winter mobility for coastal communities during this unusually cold season.

The Estonian ice roads represent a fascinating intersection of traditional local practices and modern transportation needs, allowing communities to adapt to harsh winter conditions while maintaining vital connections across the frozen Baltic waterways.
