Nebraska dissolved their House in 1930s and while they had good reasons, it passed because of the push to legalize horse betting:

After a trip to Australia in 1931, George W. Norris, then U.S. senator for Nebraska, campaigned for reform, arguing that the bicameral system was based on the non-democratic British House of Lords, and that it was pointless to have two bodies of people doing the same thing and hence wasting money. He specifically pointed to the example of the Australian state of Queensland, which had adopted a unicameral parliament nearly ten years before. In 1934, voters approved a constitutional amendment to take effect with the 1936 elections, abolishing the Nebraska Senate and the Nebraska House of Representatives and granting their powers to a new unicameral body simply called the Nebraska Legislature. At 43 members, the new Nebraska Legislature was closer in size to the old 33-member Nebraska Senate than it was to the old 100-member Nebraska House of Representatives.[7][8]

Many possible reasons for the 1934 amendment's victory have been advanced: the popularity of George Norris; the Depression-era desire to cut costs; public dissatisfaction with the previous year's legislature; or even the fact that, by chance, it was on the ballot in the same year as an amendment to legalize parimutuel betting on horse races.[9] This final coincidence may have aided the measure's passage in Omaha, where the unicameral issue was not a pressing one but horse racing was. (Gambling interests campaigned for "yes" votes on all amendments in hopes of assuring the horse-racing amendment's passage.)
