The remains of an amusement park that operated for more than six decades in Wichita are gradually disappearing.

The Wichita Eagle reports that Roger Nelson is a member of the family that has owned Joyland Amusement Park since the 1970s. He says efforts are underway to tear down the park “as soon as possible.”

Metropolitan Area Building and Construction Department director Thomas Stolz says there have been problems with graffiti and trespassing at the park since it closed in 2006.

Several buildings have already been demolished and more are scheduled. The remains of the historic wooden roller coaster are being dismantled. The Historic Preservation Alliance of Wichita and Sedgwick County is negotiating to buy a section of the track and some coaster cars.
