SOUTH BEND, Ind. (AP) – Plans are in the works for interactive light sculpture that could cast a variety of colors over the St. Joseph River in downtown South Bend.

The $750,000 South Bend River Lights is being planned for unveiling next May during planned Memorial Day weekend events marking the city's 150th anniversary.

Downtown South Bend Inc. director Aaron Perri says about 90 percent of the needed money has been raised for the project. The South Bend Tribune reports (http://bit.ly/1qjoAw0) the project will include light structures on each side of the river and lighting under the arches and on the columns of the Jefferson Boulevard Bridge.

Mayor Pete Buttigieg (BOO'-tah-juhj) says he believes it will be an appealing feature that will make the city's downtown more inviting.
