Lyons Road, North of Forest Hill Blvd To South of SR 80

American was responsible for the planning and design of improvements along Lyons Road, Dillman Road, 7th Place South, and Pioneer Road. The study examined several intersections and made recommendations as to the appropriate configurations of each. Improvements included a four-leg single-lane roundabout for the intersection of Lyons Road and Dillman Road that was designed to meet Palm Beach County standards. This intersection was previously a two-way stop along Lyons Road that allowed Dillman Road to operate as the primary roadway. Safety concerns were raised in changing this operation as it had been in place for many years. By introducing a roundabout, both roadways were given equal importance. Other improvements along the project limits included a new 0.9-mile two- and three-lane facility with 4-foot paved shoulders, improvements and paved shoulders along 0.12 miles of both Dillman Road, and 7th Place South. This project also included complete permitting and drainage design. The project falls within SFWMD’s C-51 drainage basin and also within LWDD’s jurisdictional limits. Project specifics included development of roadway component plans, signing and pavement marking component plans, and all permitting required for construction.
