Gulf of Paria crossing

The Gulf of Paria crossing is a hypothetical bridge or tunnel spanning the Gulf of Paria that would connect the island of Trinidad and South America.
Background.
Trinidad was connected to Venezuela (as also with Tobago) during the last ice age by natural "land bridges" between them. Trinidad and Tobago are part of the continental shelf of South America, and Trinidad is, at its closest, only about from the South American mainland. A mere short distance, and visible across the Gulf of Paria on a clear day. At various stages of Trinidad's post independent history, members with the government of the Republic of Trinidad and Tobago have spoken of constructing a physical link between the islands of Trinidad and Tobago to physically unify the country. As public discussion and commentary ensued over feasibility and cost, an alternative proposal was made of constructing a shorter connection which would connect Trinidad and Venezuela.
