The driver who suffered a severe medical condition and smashed into a fire hydrant Saturday afternoon on Ala Wai Boulevard has died.

Officials identified him as 47-year-old Allan Vierra of Kaneohe.

The crash happened at 2:33 p.m. Saturday between Kaiolu and Lewers Streets on the makai side of Ala Wai Boulevard in Waikiki.

According to sources Vierra was transported in critical condition and his female passenger in serious condition to Queen's Medical Center.

Nearby residents on Ala Wai Boulevard heard the crash and came to the aid of the injured driver.

"We just heard a bang so we ran out and it smelled like rubber burning," said Missy Turla. "The water was gushing and we saw a man who had some kind f medical condition and he was just lying in his seat. We were massaging his arm, trying to keep him awake, but he wasn't responsive at all."

The pick-up truck came to a rest on top of the hydrant, which continued to gush water into its undercarriage and onto the roadway.

Police initially closed the two left lanes of Ala Wai Boulevard surrounding the crash while they cleared the soggy scene. They completely closed off Ala Wai Boulevard around 3:15 p.m. to remove the truck. Traffic was rerouted onto Seaside Avenue during the closure.

Police began to remove the truck around 4 p.m. Firefighters said that the immense amount of water on the street did not flood any nearby buildings.
