American/Avalon developed construction plans for the 2-mile widening of County Barn Road from a two-lane roadway to a four-lane divided urban arterial. Close coordination was required with the County to incorporate extensive regional drainage improvements in the roadway design. A 4’x8’ box culvert was designed down the center of the roadway to carry regional flows. A special drainage design was developed to accommodate the box culvert within the roadway. Drainage ponds were incorporated into the design. The project included the design of three county utility lines (water, reclaimed water, sanitary force main), signalization, lighting and noise walls as well permitting with South Florida Water Management District and Army Corps of Engineers. All private utilities within the corridor were relocated which required extensive coordination. Multiple public involvement meetings were held to solicit public comment and address access management concerns.
