Expert Travel Tips for Your Tunnel Crossing

Safety is the top priority in the Subfluvial Tunnel. You must keep your headlights on at all times. Do not try to overtake other cars inside. The lanes are narrow and the ceiling is low for large trucks. Stay alert for the entire two-mile stretch.

The ventilation fans can be quite loud. If you have sensitive ears, keep your windows up. There are emergency phones located every few meters. If your car breaks down, stay inside the vehicle and wait. Professional towing services are usually on standby at both ends.

Avoid crossing during peak commute hours. Early morning and late afternoon can be very busy. Weekend traffic is also heavy as people head to the beaches. Check the weather before you leave. Heavy fog near the river can slow down traffic significantly. Use common sense to enjoy a safe trip.
