The name of this bridge, the Red Bridge, comes from one very simple fact. The entire 527' long structure is painted in a very bold red color, creating a very recognizable bridge.
The bridge is a landmark for the city of Des Moines, and is very well liked.
It has had a long history though. It was first built in the 1800's, and contained three truss spans, not just the two. Then some time between 1907 and 1930, it was shortened with the easternmost truss span taken out, and a through plate girder and short I-Beam placed in instead.
Then some time in the 1940's, the bridge was extended on its west end, this time with a 45' I-Beam span that was built for 3 tracks, to allow spurs to come in. This went over an access road.
By the time the bridge was abandoned in 1997, as the newly created Norfolk Southern did not need the line, it had a 20' I-Beam, a 75' through plate girder, two 155' pin connected pratt trusses, a 70' steel girder and a 45' I-Beam span.
By 2004, when plans were being finalized to convert the bridge to a trail, the I-beam span was removed, the bridge stripped of its natural silver lead based paint and repainted bright red with a more enviromentally friendly paint.
For the next two summers, work on fixing up the bridge took place. The span that was removed was replaced by a smaller I-beam span.
The bridge was inspected, stripped of it's rail tie deck and replaced with a steel deck and handrails, a very fancy way to convert the bridge. Between the two trusses, an overlook was also added.
As an added bonus, the bridge was installed with several LED lights, creating quite the sight at night too.
Out of the five railroad bridges that crossed in downtown Des Moines, this one is one of three left. Next to this bridge is the Iowa Interstate Bridge, and even further downstream was the Chicago Great Western Bridge
The two other truss bridges, the Chicago Burlington & Quincy as well as the Minneapolis & St Louis Bridges were removed in the 1970's. These were located about a block downstream from the IAIS bridge.
This bridge officially opened to pedestrians in the summer of 2006. It became part of the Principal River Walkway, something that is hoped to connect Des Moines to surrounding areas, and even to other parts of the state.
The bridge will be partially reconstructed to be raised 3 feet for flood purposes, at a cost of 3.5 million. Hopefully rule 408 will apply to block this attack on a historic structure.

The work is for a new higher floodwall. The photo below is looking at the short little I-beam span. This span did see railroad use.
