Eagan Sperry Communications Tower


When the City of Eagan, Minnesota, was making plans to decommission an aging water tower that was also being used a telecommunications site, they wanted more than a typical monopole to take its place.


The project team designed an innovative, 178-foot communications tower – complete with a programmable lighting system – in its place. The new tower features 112, four-foot color-changing LED fixtures and six flood luminaires. The tower lighting schemes can be preprogrammed or controlled remotely with specially developed computer programs.
