OKLAHOMA CITY - New riverside attractions, including hiking, biking and zip lining, are coming to Oklahoma City.

It’s something business owners Roger Skeen and Brad White have been wanting to build for years.

"We just recently signed a deal with the city that's going to allow us to utilize about 800 or so acres that's adjacent to the river,” White said.

That land will be used for a large outdoor park, called the Lost Lakes Waterpark and Entertainment Complex, and will be right next to the already existing wake board park.

The area will be used for hiking, biking, horseback riding, zip lining and much more.

"We're building a festival grounds just here on the other side of the lake, which will have a capacity of about 30,000,” White said.

One of the biggest attractions will be a large slide, with only one other like it in the country.

"It'll be a slide that's over 180 feet in length, and there will be various angles. The most extreme angle will actually kick the sliders up about 30 feet in the air, and then they'll be a smaller one and an even smaller one after that,” Skeen said.

The project is privately funded and will cost about $6 million.

Skeen and White said they think the exciting project will help boost economic development.

"We've had a tremendous amount of calls from national promoters, wanting to do large scale festival events, which we think will bring a tremendous amount of traffic to Oklahoma City,” White said.

"It'll bring a ton of out-of-towners in that not only will stay here but we hope to fill up motel rooms in the downtown Oklahoma City area,” Skeen said.

The first part of the project will be constructing the slide, which the owners hope to have open sometime in July, and they expect to have the entire place completed by August.
