I-5 Portland: Exit 299B (City Center/I-405)

Exit 299B (City Center/I-405) is a high-traffic junction in the heart of the Portland metropolitan area. This exit serves as the gateway to downtown Portland and the connection to I-405. For professional drivers, this area is strictly a transit zone; it lacks the infrastructure to support long-haul staging or commercial vehicle services.

Parking Availability & Type

Parking Status: The area is intensely urban, consisting of high-density commercial, residential, and government buildings. Overnight parking for tractor-trailers is prohibited throughout the downtown core.

Warning: Do not attempt to use unofficial parking on city street shoulders or industrial dead-ends within the Portland city limits. Parking enforcement is extremely proactive, and unauthorized commercial parking will likely result in a citation or tow.
