CENTRAL BOULEVARD RECONSTRUCTION AND TUNNEL

Palm Beach Gardens, FL

This reconstruction of a one-mile arterial road in Palm Beach County required construction of a tunnel for the Old Palm Golf Club private residential development. Roadway improvements included raising Central Boulevard approximately 11.5 feet to accommodate a 10-foot by 26-foot cast-in-place tunnel with a slab elevation at approximately eight feet. Additionally, existing stormwater management facilities were evaluated and designed to address grade changes associated with raising the roadway. A three-phase duplex stormwater pumping station was also designed to ensure that the tunnel remains dry at all times.
