Residents near Óseyrarbraut in Hafnarfjörður have been raising complaints about a persistent foul odour linked to bitumen operations carried out by road construction company Colas Ísland, according to Morgunblaðið (mbl.is). Local authorities say they are actively working toward a resolution.
The smell has prompted a wave of reports to municipal officials, and the matter is now being treated as a formal concern. Hafnarfjörður, a coastal town of roughly 30,000 people located just south of Reykjavík along the Reykjanes Peninsula, is one of the more densely settled communities in the capital region — meaning even localised industrial odour can affect a significant number of households.
Colas Ísland, a subsidiary of the international Colas Group, is one of Iceland’s major road surfacing and asphalt contractors. The company’s work along Óseyrarbraut appears to be the source of the bitumen smell that has been drifting into nearby residential areas.
What is causing the Hafnarfjörður smell?
Bitumen — the dense, petroleum-derived material used as a binder in asphalt — is well known for producing a strong, acrid odour when heated during road laying. The smell can travel considerable distances, particularly in calm wind conditions, which are not uncommon in sheltered coastal areas like Hafnarfjörður’s inner harbour district.
Óseyrarbraut runs along the eastern edge of the town, close to the shore of Hafnarfjörður bay. Construction and resurfacing activity there would be consistent with ongoing infrastructure work in the broader capital region, where road maintenance is a regular fixture of the warmer months. Summer is typically when Iceland’s road authorities schedule the bulk of surface work, taking advantage of longer daylight hours and drier conditions.
Reports indicate that multiple residents contacted the town with complaints, suggesting the odour was not a brief or isolated incident but something sustained enough to prompt official attention.
Authorities working toward a fix
Municipal officials in Hafnarfjörður have confirmed they are engaged with the issue and are pursuing a solution. The exact nature of the proposed remedy has not been detailed publicly, but the acknowledgment that a process is underway signals that the complaints were taken seriously.
Bitumen-related odour complaints are not entirely unusual in Icelandic towns during road construction season. Still, the scale of reports in this case appears to have elevated it beyond routine nuisance territory. Whether the resolution involves changes to Colas Ísland’s working hours, methods, or the use of lower-emission bitumen products remains to be seen.
Colas Ísland has not issued a public statement as of the time of reporting. The company handles significant volumes of asphalt work across Iceland each year, including major contracts for the Vegagerðin, the Icelandic Road and Coastal Administration.

What residents near Óseyrarbraut should expect
For those living close to the affected stretch of road, the immediate outlook will depend on how quickly the parties involved can agree on practical measures. If road work continues at the same pace and with the same materials, the smell is likely to persist until the project is complete or conditions change.
Wind direction plays a significant role. Hafnarfjörður sits at the foot of the Hafnarfjall highlands, and onshore breezes from the bay can funnel odours directly into the residential streets that run parallel to Óseyrarbraut. Locals familiar with the area will know that summer evenings, when the wind often drops, can make industrial smells linger well past working hours.
Authorities have not indicated a specific timeline for when the situation is expected to be resolved, but the issue is understood to be under active review. Further updates from the town are expected as talks with Colas Ísland progress.
