Greenville's unique Liberty Bridge honors Liberty Corporation founder W. Frank Hipp and his children, Francis M. Hipp, Herman N. Hipp, B. Calhoun Hipp, and Dorothy Hipp Gunter for their commitment and contribution to the Greenville community. A great place to get your feet wet.

Settling Greenville
While bridges with similar structural concepts have been built in Europe, this bridge is unique in its geometry and there is nothing like it in the United States.
Below the bridge the 28 foot Reedy River Falls is the site where Greenville�s first European settler, Richard Pearis, established his trading post in 1768. Later he built grist and saw mills at this same location which was the hub of early industry in Greenville until the 1920s.

At 345 feet long, 12 feet wide and 8 inches thick, the concrete reinforced deck is supported by a single suspension cable. The deck's distinctive curve has a radius of 214 feet and it is cantilevered toward the waterfall from supporting cables on the outside. The bridge deck also inclines 12 feet or 3% from east to west over the river.

Supports & Stability
There are 3 primary cable systems that work with and against each other to support the bridge and hold its position. Underneath the deck, three 80 millimeter diameter �ring� cables provide support and place it into compression in the horizontal plane. The 28 millimeter hanger cables work against the ring cables horizontally and with them vertically.

The hanger cables are set at 35 to 60 degrees from vertical and are supported by the catenary or main cable. The main cable is actually 3 separate 80 millimeter cables � 2 spanning from the abutment blocks to the steel mast and 1 spanning from mast to mast in the center of the span.

The 2-90 foot tall masts weight more than 28 tons each and lean away from the bridge at a 15 degree angle. There are 80 millimeter backstay cables that hold the masts in position. Steel piles and rock anchors, 70 feet deep into bedrock, transfer the bridge loads to the ground at the abutments, mast and backstay foundations.
