Working closely with the Florida Department of Transportation (FDOT), B&N re-evaluated plans for a partial cloverleaf interchange at I-75 and Fruitville Road, which was known for gridlock.
B&N prepared an Interchange Modification Report (IMR) to re-evaluate future traffic operations based on updated population/traffic growth projections using VISSIM microsimulation analysis. The IMR concluded that a Diverging Diamond Interchange (DDI) was the preferred alternative, rather than the previously approved partial cloverleaf interchange with an arterial traffic separator. Traffic data and Bluetooth Travel Time and Origination-Destination data was collected and used to analyze speed trends and vehicle route patterns.
B&N designed the project, which included the widening and reconstruction of 1.95 miles of I-75 to accommodate the future 10-lane interstate typical section and the widening and resurfacing of 1.64 miles of Fruitville Road to accommodate the DDI configuration. The work on Fruitville Road also provided additional capacity improvements from Honore Avenue to Coburn Road.
