WASHINGTON -

 A Tyrannosaurus rex skeleton bound for the Smithsonian Institution is set to arrive in Washington in April as a new home is built for the specimen on the National Mall.

The National Museum of Natural History announced Friday that the T. rex unearthed in Montana in 1988 will arrive in the nation's capital April 15. The Smithsonian is planning a new 31,000-square-foot dinosaur hall that is scheduled to open in 2019.

On April 28, the museum will close the current fossil hall to begin a complete redesign and renovation. But Museum Director Kirk Johnson says dinosaurs will continue to be on view during construction.

The museum has unveiled a new display featuring a cast of the T. rex skull. Next year, the museum feature fossils from the dinosaurs' last days.
