Starting at the Omaha side of the river, the bridge featured a short through truss span, a longer deck truss span, a main channel through truss about 200 feet long, then a lengthy series of deck truss spans on the Iowa side of the river crossing the east half of the Missouri River as well as the river flats area. At some point in the bridge's lifespan, the structure was expanded to double its width. One addition pier was added to the downstream side of the bridge next to each pair of existing bridge piers. The truss spans were then doubled in width by adding structure to the downstream side of the existing trusses. I have not determined when this expansion took place, but it probably happened about the time that cars became popular in the 1920s.
Once cars did become common on the bridge, local residents started to complain about those tolls. To address the toll problem, a local charity called the Knights of Ak-Sar-Ben purchased the bridge in 1938, as well as the South Omaha Bridge, with the intention of eventually removing the tools. The Knights first had to pay off their bridge debt, but followed through with removing the tolls in 1947. The name Ak-Sar-Ben is Nebraska spelled backwards. This is somewhat tongue-in-cheek since the name was picked after someone commented that everything was going backwards in Nebraska at the time the organization was founded in 1895 to save the Nebraska State Fair.
The Ak-Sar-Ben Bridge was becoming obsolete in the 1960s due to its light iron structure. When the Interstate highway system was planned, Interstate I-480 was planned to run just north of downtown Omaha, with the mainline I-80 bypassing downtown to the south. I-480 featured a long elevated expressway on the north side of downtown, then a long steel girder bridge over the Missouri River, where it connected to Interstate I-29 just after entering Iowa. The I-480 bridge opened in November 1966, at which time the Ak-Sar-Ben Bridge closed. Local residents attempted to keep the Ak-Sar-Ben Bridge as a pedestrian walkway, but that was not to be. The old structure was removed in 1968. All that remains today is a single set of bridge piers standing tall in the Missouri River just east of the navigation channel near the Iowa shore.
By the way, Omaha did eventually get its pedestrian bridge over the Missouri River when the magnificent Bob Kerrey Pedestrian Bridge opened in 2008. This signature cable stayed structure has proven to be popular with local residents as well as becoming a tourist attraction.
Road scholar Jeff Morrison has researched the highways that used the Douglas Street Bridge, and later when it was known as the Ak-Sar-Ben Bridge. Here are his findings, and reproduced from the Iowa Highway Ends web site:
|1926 - 1931||US-30, US-75|
|1931 - 1934||US-6, US-30S, US-75|
|1934 - 1939||US-6, US-30A, US-75|
|1939 - 1941||US-6, US-30A, US-75, US-275, IA-92|
|1941 - 1960||US-6, US-30A, US-75, IA-92|
|1960 - 1966||US-6, US-30A, US-75|
The only remaining part of the Ak-Sar-Ben Bridge is a single set of iron piers in the middle of the Missouri River located just downstream from the Interstate highway I-480 Grenville Dodge Bridge. Douglas Street ends on the Nebraska side of the river at South 8th Street, about 1,000 feet short of the river. The Nebraska side was extensively landscaped to build a park, so there are no traces of the old bridge remaining in Omaha. On the Iowa side, the right-of-way for Broadway Street is still visible between the levee and Interstate highway I-29.
