Construction Delays During construction of the park, developer Mike Ferguson halted excavations after the
Army Corps of Engineers told him they wanted him to stop due to controversy and the lack of a required
permit for building in the
Snake River wetland. Work was halted in late April-early May 1998, but by that point most of the work for the park was already completed. According to the terms of the
Clean Water Act, developers are required to show that they will do no or little damage to wetlands before work is begun. There is no evidence that Ferguson knew that he needed such permits in advance of beginning development. On May 28, 1998,
Madison County Commissioners voted to grant Mike Ferguson a permit to allow construction on the wetlands where the park was to be located. The vote was unanimous after local residents showed strong support for the project. This was the last step the park needed from county government officials for construction to be completed. On June 12, 1998, the first of Bear World's bears arrived, two days after Ferguson reached an agreement with Idaho wildlife officials who gave him permission to bring in the bears on a temporary basis. This move allowed Ferguson an opening to temporarily avoid a ban on the commercial
importation of
black bears.
Direct Highway Access Closure In 2016, the
Idaho Department of Transportation started construction on the Thornton Interchange on
Highway 20. When the interchange was completed in early 2017, it closed off the direct access to Yellowstone Bear World from Highway 20. Now visitors must follow
signs, taking a less convenient route through
backroads. According to Courtney Ferguson (
general manager of Bear World) the closure of the direct highway access resulted in a 10% drop in
business. A
frontage road was later constructed to the west of Highway 20 to reinstate direct access. The road opened on May 30, 2019. ==Attractions==
