The Mt. Rainier Scenic Railroad trestle bridge fire is contained but still smoldering, railroad personnel confirmed Sunday.
Firefighters with the state Department of Natural Resources (DNR) were on scene throughout the weekend and will continue monitoring the fire until it is fully extinguished.
The cause of the fire remains under investigation, though officials told The Chronicle it was “human-caused.”
The bridge, located between Mineral and Morton, caught fire at about 6:30 p.m. on Wednesday, April 30. A large portion of the bridge collapsed at approximately 5:22 p.m. on Thursday, May 1, with a secondary collapse at 5:35 p.m. that same day.
As of Sunday afternoon, Mt. Rainier Scenic Railroad reported that a few spans of the 28-span trestle bridge were still upright on either end of the bridge due to support from the suspended rail.
“They’re unlikely to collapse on their own, which makes cleanup and mitigation even more complex,” Mt. Rainier Scenic Railroad stated in a social media post at about 4 p.m. on Sunday. “We don’t have answers there yet — but it’s going to be a daunting process.”
A bridge engineer with Railstar Engineering, LLC, will be on site this week to help determine “a ballpark replacement cost,” according to Mt. Rainier Scenic Railroad.
“He’s graciously offering his services pro bono to help us estimate costs and start working on a plan to move forward,” Mt. Rainier Scenic Railroad stated in a social media post at about 8 p.m. on Sunday. “We know a lot of folks have been questioning what rebuilding it would look like and we wanted to let you know, we hope to have those answers soon.”
While the trestle fire has not impacted Mt. Rainier Scenic Railroad’s regular operations, it will likely have significant negative impacts on the railroad’s plans for restoration and growth over the coming years.
