The I-4 and Highway 408 interchange in Orlando, Florida, serves as a critical link between two major highways, facilitating regional transportation. Renovations and expansions have been undertaken to accommodate growing traffic demands, including the construction of a prominent flyover ramp from westbound I-4 to eastbound Highway 408. However, the presence of subsidence, typical in Orlando's karstic terrain, presents inherent risks to the foundations of the interchange. Therefore, satellite-based monitoring plays a pivotal role in detecting and mitigating these risks effectively.
