A landscaped pedestrian skybridge over Interstate 15 — far more elaborate than a typical cement walkway — was one of several enticements offered by Dreamscape Cos. CEO Eric Birnbaum to the Oakland A’s if the team had accepted a proposal to build a baseball stadium at the Rio Hotel & Casino.

It doesn’t matter that the team chose another site a mile-and-a-half south for its planned $1.5 billion stadium.

Birnbaum still plans to bring the skybridge concept to the Rio.

The proposed structure is loosely based on New York City’s High Line, a one-and-a-half-mile elevated walking trail built on top of a portion of the New York Central Railroad on Manhattan’s west side.
