A significant fire erupted Tuesday afternoon at a three-story apartment building under construction in Cheyenne, drawing a large multi-agency response and prompting crews to prioritize containment to protect neighboring homes. The blaze at 2505 E. Carlson St. was controlled before nightfall, but officials say the scene remains active as investigators work to determine the cause.
Emergency dispatchers sent units just after 3:30 p.m.; the first engine reached the site within minutes and reported heavy smoke and visible flames coming from the structure, which sits behind several existing apartment complexes. Strong winds and limited site access complicated operations and increased the risk to nearby buildings.
Response and tactics
Faced with rapid fire spread and safety concerns, crews shifted to defensive tactics. Firefighters used an aerial master stream and handlines to shield neighboring structures while attacking the main body of the fire from safe positions.
