A large fire engulfed an apartment building under construction in Denver, authorities said, as thick smoke rose over the city and crews rushed to contain the blaze. The fire broke out early Friday and spread quickly through the unfinished structure, according to Reuters.

Because the building was still under construction, flames had access to exposed materials. As a result, firefighters faced difficult conditions while trying to prevent the fire from spreading to nearby buildings. Officials said no fatalities were reported, although the situation caused widespread disruption.

🚒 Firefighters Battle Intense Flames

Fire crews responded swiftly after receiving reports of the blaze. Firefighters worked from multiple angles to control the flames, using ladder trucks and ground hoses. However, strong winds and the size of the structure made the response more challenging.

Officials said the fire produced heavy smoke that was visible across parts of Denver. Because of safety concerns, emergency teams kept residents at a distance while crews continued their work. Firefighters remained on the scene for several hours to fully contain the fire and prevent flare-ups.

⚡ Power Outages Hit Surrounding Areas

The fire also triggered power outages in nearby neighborhoods. Utility officials said flames damaged electrical infrastructure, forcing crews to shut off power as a precaution. As a result, thousands of customers temporarily lost electricity.

Restoration efforts began once conditions allowed utility workers to access affected lines. Officials warned residents that power restoration could take time, depending on damage assessments. Meanwhile, authorities urged people to avoid the area to allow emergency operations to continue safely.

🚧 Evacuations and Public Safety Measures

Although the building was unoccupied, officials evacuated nearby residents as a precaution. Emergency services said the evacuations helped reduce risk while firefighters battled the blaze.

Police closed roads around the construction site to keep the public away. In addition, authorities advised residents to keep windows closed due to smoke. Public safety officials said these steps were necessary to protect health and maintain order during the emergency response.

🔎 Investigation into Cause of Fire

Once crews brought the fire under control, investigators began examining the scene. Officials said they will review construction materials, equipment, and site conditions to determine how the fire started.

At this stage, authorities have not released a cause. Investigators said they will provide updates once they complete their review. Construction site fires can spread rapidly, especially when structures lack completed fire-suppression systems.

🏙️ Impact on City and Next Steps

City officials said the incident highlights the risks associated with large construction projects in dense urban areas. They also stressed the importance of safety planning and rapid emergency response.

As cleanup continues, authorities will assess structural damage and determine when roads can reopen. Meanwhile, residents and businesses affected by the outage are awaiting full restoration of services.
