paraFlorida DOT had awarded engineering consulting firm Greenhorne & O'Mara (G&O) a contract to prepare construction contract documents for the 6 mi of Interstate 95 through the City of West Palm Beach and Palm Beach County. The contract called for G&O to submit a Lighting Justification Report for FDOT. A benefit-cost analysis had to prove that new lighting would achieve twice benefit in crash reduction costs when compared to the new lighting costs. A range of lighting techniques was used to illuminate travel lanes and ramps on the Interstate, which included conventional light poles, median barrier-mounted dual-arm light poles, and ground-mounted single-arm light poles.

FDOT's standard design solution was to provide six aluminum light poles with 50 ft mounting heights each situated on a pilaster attached to the proposed bridge widening sections./para
