"The History of Grundy County" (1881) mentions that the county contracted with the Missouri Valley Bridge Co. in 1876 for a 192-ft Whipple truss bridge over the Grand River at Trenton with a cost of $4876.80. This is probably the same bridge.

The Trenton Bridge was just south of the city over the old Grand River channel. It was built in 1870 by Smith Truss Bridge Company at cost of $9,000 dollars. Iron piers were added later at cost of $1,800. (40.066N ,93.621W). The bridge was repaired 1877 which the 1881 source cited. There was a major flood in 1909 that moved the county to straighten the river channel. With the completion of the Charlie Dye Bridge in 1923 the channel was changed and the Trenton Bridge was no longer needed. The Trenton Bridge was removed in 1937 and replaced with a concrete culvert. The site of the bridge had been the Benson ferry crossing from 1846 until 1870.

Actually the Grand River does not go through Trenton. The Thompson River is sometimes refered as the Thompson Branch of the Grand River.
