HOUSTON — When voters in Houston head to the polls today, they could be deciding whether shuttered Astrodome is saved or razed.

A referendum on today’s ballot would authorize up to $217 million in bonds to transform the so-called “Eighth Wonder of the World” into a giant convention and event center and exhibition space. Houston-area leaders have said the stadium that was once home to professional baseball and football teams would likely be torn down if the ballot measure fails to pass.

Houston resident Wilton Schexnayder, 62, said he plans on voting in favor of the referendum.

“I think they should preserve it,” he said.
