Driving Change: How Innovation and 3D Modeling Transformed Miami’s Turnpike

Like other major metro areas in the U.S., Miami is no stranger to congested roadways or rush hour traffic. With more than 1.4 million passenger vehicles on Miami-Dade County roads annually—and the population expected to reach 3.3 million by 2040—the region’s transportation infrastructure is under increasing pressure. According to the INRIX 2024 Global Traffic Scorecard, Miami ranks sixth in the nation for worst traffic congestion, with drivers losing nearly 75 hours each year to delays.

To help relieve that burden, Florida’s Turnpike Enterprise recently completed a $235 million construction project to widen the Homestead Extension in Miami-Dade County. The 8-mile-long expansion included work at 16 bridge sites and two complex structures, along with the modernization of six toll facilities and aesthetic improvements to meet anticipated future growth and demand.

But infrastructure improvements go beyond asphalt and bridges. Technology—specifically, Intelligent Transportation Systems (ITS)—plays a critical role in improving safety, efficiency and sustainability on today’s roadways. ITS uses sensors, cameras and communication networks to monitor traffic conditions, manage congestion and deliver real-time updates to drivers.

As the ITS designer for the project, Jacobs developed a system that included fiber optic cable communication, closed-circuit TV cameras, dynamic message signs, toll rate message boards, vehicle detection systems and a travel time tracking system. Jacobs also handled the design of sign structures.

While the original design called for express lanes, Florida’s Turnpike later shifted to a managed lanes approach. Jacobs quickly revised the design to meet the new requirements—demonstrating both agility and deep coordination among teams.

A standout feature of the project was a 3D model of the entire corridor. This digital model helped verify traffic camera placement to ensure clear, unobstructed views of the roadway. Another innovation involved placing conduit infrastructure on the same side of the road as device and cabinet installations, which reduced fiber crossings and future maintenance needs.

“This was a fast-paced design with extensive coordination between teams," says Jacobs Engineer-of-Record Ernest Sackey. "Our familiarity with each other was key to the project’s success. The Homestead Extension will significantly ease traffic for Miami commuters, reducing travel times and improving mobility. With road demand only projected to rise, these improvements are crucial.”

Thanks to its innovative design and strong collaboration, the project earned a Grand Award at the 2025 ACEC Florida Engineering Excellence Awards in Orlando.
