Alton Lake Crossing Retaining Wall

The Alton Development in Palm Beach Gardens contains a major lake crossing between the residential neighborhoods north of Grandiflora Road and the commercial parcel adjacent to Donald Ross Road. To link these distinct areas a dynamic roadway crossing was needed.

WGI designed a 200-foot long arched lake crossing with two parallel retaining walls. These retaining walls included large at-grade planters for trees and eight-foot and ten-foot wide pedestrian and bike shared-use paths offset from the roadway by four-foot green spaces woven into the sidewalk alignment. The exterior parapet walls of the crossing included two large cantilevered overlook viewing and seating areas at the center of the lake crossing. Special lighting was integrated into the decorative parapet columns along the crossing perimeter.

This integrated roadway, landscape, hardscape, and pedestrian-friendly crossing provides a key gateway between the residential and commercial areas of the development.
