History
Monticello was platted in 1854. A post office has been in operation at Monticello since 1855. Monticello was incorporated in 1856. The nearby village of Moritzious merged with Monticello in 1891. On May 3, 2006, the Monticello Middle School had an electrical fire from the large amount of rain settling on the roof. The smoke damage to the school caused the school to be closed for the rest of the school year. As a result, middle school and high school students had to share usage of the high school building on an alternate-day schedule. The school year did not get extended, and the clean up was completed in time for the 2006–07 school year.
Economy
In anticipation of rapid population growth, Monticello created a comprehensive growth plan in 1996. A new high school was constructed in 1999. A new highway interchange was completed in 2006 on the east end of town, allowing residents full access to Interstate 94 from Wright County Road 18. Since 2002, many retail outlets have been constructed, including Fleet Farm, Wal-Mart Supercenter, SuperTarget store, Muller Family Movie Theatre, River City Extreme Bowling & Restaurant, Home Depot, Marshalls, Applebee's, Taco John's, Arby's, Dollar Tree, Auto Zone, Aldi and Goodwill. This planned growth has also brought new auto dealerships, hotels, and industrial development. A 2004 annexation agreement with Monticello Township is expected to help sustain Monticello's growth for the next twenty years.
