Many bridges that use these triangular frames(trusses)are suspension bridges. Like the Mid Hudson bridge for example. Some suspension bridges have their trusses placed below their decks so there is less veiw obstruction. The Mid Hudson bridge and the Whitestone bridge have their trusses placed above their decks and that's why you can see them when driving over them.
