The old Muda River Railway Bridge is a now disused bridge across Muda River, between Penang and Kedah. The place on both sides of the river is called Pinang Tunggal (though the Kedah Pinang Tunggal is bigger and more prominent). As the old Muda River Railway Bridge has been decommissioned, it has been fenced up to prevent people from entering it and accidents occurring on it.
