Officials are betting the new attraction will lure more visitors the downtown area, which has struggled to compete with the flashier Strip three miles away.
It is intended to reflect the "vintage Vegas" vibe that characterizes the promenade, nicknamed "Glitter Gulch" for the classic casino signs that glow amid the souvenir shops and buffet signs.
Riders will be able to stop halfway, or continue to the end of the 1,700 course, landing near the Golden Gate casino. They will have the option of flying along the lines in a horizontal "superman" position, and accelerating their ride using a new "power launch" system.
Bootleg Canyon Flightlines operates the current ride. The new structure will be built by the Hawaii-based company Skyline, better known for zip lines that span waterfalls and forests.
