(Portland, OR) -- The Portland Bureau of Transportation is spending 50-thousand-dollars from the city's gas tax to improve visibility for drivers near schools. Parking spaces are set back 20 feet near intersections and crossings, to make pedestrians more visible to drivers. 200 intersections and crossings are being updated. Work is expected to get underway in the coming months. Crews will begin curb painting work within three months, and new parking signs will start going up within the next six months.
