Trestle Fire wins Run-Off; I-5 Skagit River and New Castle Bridges tied for second.
All it took was a combination of heat, dry weather and a spark from a passing train, and a 900-foot long wooden trestle bridge with a more than 100-year history, was engulfed in flames. 30 seconds later, it all came tumbling down, like a stack of dominoes. The San Saba Trestle Bridge near Lometa (located 90 miles west of Waco) spanned the Colorado River and featured a steel through truss span over the river and hundreds of feet of wooden trestle on the west end. Yet its demise created some curiosity among the readers as seen in the video here. If a teacher shows this disaster to the students in class and they are awed by the sequential cascading disaster, as one of the voters noted, then there is no wonder that the San Saba Bridge would receive the devious prize it deserves. After a week-long run-off vote, the Texas trestle received the Spectacular Disaster Award because of the intense effects of the fire and the bridge’s sequential disaster that followed seconds later. The video shown of the disaster will definitely be shown in many engineering and physics classes to show how dangerous a fire can do to a structure, whose melting temperature is low enough for it to collapse. A devastating loss for the railroad, for it needs $10 million to replace the trestle approach spans, but one that created a lot of curiosity among bridge engineers and scientists alike.
The Trestle beat out the New Castle and Skagit River Bridge Disasters, as they were tied for second place, missing out by only two votes each. This marks the first time in the history of the (recently changed) Author’s Choice Award, that two bridges received two different awards or honorable mentions in two different categories. The New Castle Bridge west of Oklahoma City had already received the Award for the Worst Preservation Example as the 10-span through truss bridge over the Canadian River was reduced to only one span, thanks to a tornado that destroyed two spans and the city government’s decision to demolish all but one of the remaining spans. It was the same tornado that destroyed Moore and devastated vast parts of Oklahoma City.
The Skagit River crossing in Washington state had received the honorable mention for the Biggest Bonehead Story, as a truck driver dropped the southernmost span into the river after hitting the portal bracing. While this incident raised the debate on what to do with through truss bridges, suggestions by local politicians were above and beyond. The collapsed span has since been replaced and I-5 has returned to normal.
The Bridgehunter’s Chronicles would like to thank everybody for voting in this year’s Ammann Awards and parts of the Author’s Choice Awards. As mentioned in the previous article, the voting format and the dates of the voting for this year’s 2014 Ammann Awards will be different as there will be more options but more simplicity to encourage people to vote on their candidates. It may be like the Bridge Bowl, but it might serve as a way to talk about the bridge candidates at the table, while serving traditional foods over the holidays. Entries will be taken in November, as usual, so go out there and get some pics, write about your favorite bridges and nominate your favorite historian.
Minus the Post Humous version of the Lifetime Legacy, let’s head back out there and look at the bridges that need your help regarding preservation, shall we?
