Traffic signal improvements at PGA Boulevard and Shady Lakes Drive will begin Tuesday, October 31 in Palm Beach Gardens. A single outside lane, eastbound and westbound, will be closed as needed along PGA Boulevard at the intersection of Shady Lakes and Hickory Drive. The contractor will be installing the foundations for the new mast arms for the northeast and southwest corner of the intersection with lane closures at Hickory Drive during the foundation installation. The lane closure will be used to install a new mast arm structure and remove the existing mast arm structures. This work has been approved by FDOT through Wednesday, December 20, 2017.
