SIOUX CITY, Iowa (KCAU) – UPDATE: Officials gave more details on the incident on I-29 that took place Wednesday afternoon.
Police said that fire along I-29 sparked in a homeless camp under a culvert along the interstate. That culvert is located just south of Tri-Vew Avenue and the Hard Rock Hotel.
Fire crews responded to the scene to discover propane tanks were also located under that culvert.
It all started just before 2 p.m. when firefighters noticed smoke coming from the culvert below I-29. Sioux City Fire Rescue said the first started in a homeless camp set up in the space.
It quickly turned into a massive plume of black smoke that could be seen throughout downtown Sioux City. They said propane tanks in the camp exploded, quickly fueling a major fire.
“What made this particularly difficult is this is a box culvert that goes underneath this bridge, a box culvert is a way for water to drain through the area, as such the Iowa DOT has a membrane over the culvert to protect the concrete. That membrane is flammable which aided in the development of the fire,” Ryan Collins with the Sioux City Fire Rescue said.
Officials with the Iowa DOT were on the scene all afternoon inspecting the structural integrity of the interstate. They re-opened the southbound lanes but are still working to fully inspect the area under the northbound lanes for damage before opening the interstate back up to traffic.
There is still no word yet on when that inspection might be complete, so for now, dozens of emergency crews are spread throughout downtown Sioux City directing traffic. They’re asking everyone to slow down, pay attention and be patient.
