A man suffered only minor injuries this morning after his vehicle crashed through a guard rail and plunged 25 feet, landing upside down on top of a Dumpster in downtown Seattle this morning.

The man’s brakes may have malfunctioned or there may have been some other mechanical problem since the driver was honking his horn as he drove west on Seneca Street towards First Avenue, said Seattle police spokeswoman Debra Brown. He crashed through a guardrail near the Seneca Street off ramp from the Alaskan Way Viaduct at 10:30 a.m. and fell approximately 25 feet onto the Dumpster on Western Avenue.

The guardrail slowed the driver’s momentum and the Dumpster “probably absorbed a lot of the impact,” Brown said.

Less than 20 minutes earlier, another driver suffered life-threatening injuries after he crashed into a building and utility pole on Elliott Avenue.

Medics performed CPR on a man as they took him to Harborview Medical Center after he apparently lost control of his vehicle at 10:12 a.m., slamming into the RealNetworks building at 2601 Elliott Avenue and coming to rest against a pole, said Helen Fitzpatrick, a spokeswoman for the Seattle Fire Department. The man was unconscious when he was pulled from his vehicle, she said.

The man was traveling at high speed as he drove west on Cedar Street, Brown said. The man, who was not carrying identification, went through a green light at the T-intersection with Elliott Avenue and crashed into the building. He suffered life-threatening injuries in the crash, she said. “He was in pretty bad shape,” Brown said, adding there was minimal damage to the RealNetworks building.
