PROJECT HIGHLIGHT
Hot Springs Creek Greenway Trail Bridge
The Hot Springs Creek Greenway Trail runs through town along the historic waterway and will eventually link downtown Hot Springs, AR with Lake Hamilton, 4.5 miles to the south. The 276′ long Phase V section of the trail, just north of Golf Links Road, is very narrow and uneven. It was determined that an elevated boardwalk would be the most cost-efficient way to extend the trail through this difficult section.
The FSGC team designed and installed the micropiles, steel pile caps, and steel bridge bents to support the pre-fabricated concrete trail bridge.
