A multi-vehicle accident involving two semi-trucks and multiple sedans occurred on the off-ramp from Westbound State Route 37 to Southbound State Route 29. The collision resulted in significant damage to several vehicles, including a black sedan with major rear-end damage and a red sedan with major front and rear damage. All lanes of the off-ramp were blocked, prompting a SigAlert and the full closure of the ramp. Emergency services, including an ambulance and several tow trucks, were requested and requested to handle the heavy-duty recovery of the semi-trucks. Traffic was heavily delayed as authorities worked to clear the scene.
