They closures will primarily affect streets along designated neighborhoods which have lower car traffic in general, according to KGW8. Temporary barricades and signage will be installed to alert drivers of the closures.

The plan also includes expanding space for pedestrians along streets that are "narrow or missing sidewalks," and provide more room with pop-up walking and biking lanes.

In business districts, PBOT said they'll establish space so customers can line up with enough physical distance, and create dedicated loading zones for pickup and delivery.

The city of Portland has seen a dramatic spike in speeding since the pandemic began and a major decrease in traffic congestion.
