What is maligno sa tulay?

As an AI language model, I can not confirm any information about "Maligno sa Tulay" as I am unable to process any specific context for this phrase. However, "Maligno" is a Tagalog term that generally refers to an evil spirit or a demon, while "tulay" means bridge in English. There are some folk tales and urban legends in the Philippines that suggest that some bridges are haunted by evil spirits or ghosts, but these stories are not based on any proven scientific facts. It is important to note that such stories are typically considered myths and should not be taken seriously without proper evidence and examination.
