A tragic incident on Thursday morning resulted in a deadly crash, leading to the closure of all lanes on I-5 South near the Marquam Bridge in Portland, Oregon. The accident, involving a motorcyclist and no other drivers, took place at approximately 9:46 a.m., prompting a swift response from the Portland Police Bureau's North Precinct officers.

Upon their arrival at the scene, authorities discovered a motorcyclist lying on the ground while bystanders attempted to administer first aid. Urgent measures were taken to transport the injured individual to a nearby hospital. Regrettably, the motorcyclist succumbed to their injuries and was pronounced dead at the medical facility. At present, no additional information on the identity of the victim has been released.

Given the severity of the crash, officials have announced that the closure of I-5 South is expected to last for several hours. Alternative routes have been advised for motorists traveling southbound, with traffic being diverted to I-405 South, I-84 East, or the Morrison Bridge downtown. Furthermore, several ramps have been closed, including the on-ramp from northbound I-405 Fremont Bridge to I-5 South, as well as the I-84 West ramp to southbound I-5.

In order to alleviate congestion, westbound I-84 traffic has been advised to reroute onto I-5 North and subsequently onto I-405 South. Motorists are urged to exercise caution and follow the guidance of authorities during this period of detours and closures.

The Portland Police Bureau's Traffic Investigations Unit is actively seeking witnesses to the deadly crash and encourages anyone with information to come forward.
