BHC Pic of the Week Nr. 140: Tribute to James Baughn-Easter Edition Part 1

This week’s Pic of the Week features a two-pic special in observance of the Easter holiday weekend. The first part will be showcased today on Easter Saturday, the second part on Easter Sunday- all in honor of the bridgehunter webmaster himself, James Baughn.

Today’s Pic takes us to Chester, Illinois and this bridge, the Gage Junction Bridge. This pic was taken by Mr. Baughn in 2013 at the time where Spring is beginning to take its course with the blossoming of trees and the melting of the snow. When this pic was taken, the river levels were higher because of the run-off caused by the melting snow. Nevertheless, this shot deserves recognition for its beauty as the greening process takes its course.

The Gage Junction Bridge is one of the newer versions of the truss bridge. The bridge features a polygonal Warren through truss span supported by multiple plate girder spans. The portals are Washington-style (WA) and the connections are riveted. The total length is 1380 feet; the truss span is 240 feet. The bridge is located over the Kaskaskia River just above the Lock and Dam northwest of Chester, in Randolph County, Illinois. It was built in 1976 replacing a swing bridge that had been built in 1903 but was destroyed in a train wreck in 1975. Union Pacific continues to operate the line and this bridge to this day.

The Gage Junction Bridge represents an example of truss bridges that were still being used during the 1970s. Even though truss bridges became rare to build because of other bridge designs that were more commonly used, such as beams and girders. However, in the past decade, there has been an increase in the number of truss bridges being built. Even though nine out of ten newer truss bridges have been built for railway traffic, we have seen new truss bridges that have been built either for pedestrian use, like the Sutliff Bridge in Johnson County, or for roadway use, like the Motor Mill Bridge in Clayton County– both located in Iowa. We’re not talking about the mail-order-truss structures that are welded together at a manufcaturing company and installed on the spot. We’re talking about truss bridges that are put together and supported by riveted connections and feature genuine portal and strut bracings, V-laced vertical beams and upper and lower chords. And they are built together onsite and over the river. 🙂

This leads me to some questions for you to ponder:

  1. How historically valuable are these modern truss bridges compared to the ones built between 1870 and 1940, including those made of iron and also those with special (ornamental) features?
  2. Will truss bridges make a comeback and become another option for bridge building? We’re seeing many examples of such bridges dating back to the 1980s and later in places like Indiana and Ohio. But what about the other states?
  3. What truss designs are used to construct modern truss bridges and which ones would you like to see built?
  4. And lastly, what’s a typical truss bridge to you and in your opinion, will these modern truss bridges meet your own expectations?
