The traffic speed limit on the Morrison Bridge has been reduced from 35 to 25 miles per hour. New speed limit signs were installed on March 19. Reducing vehicle speeds is one of several steps Multnomah County is taking to keep the bridge in service until the deteriorating lift span deck is replaced. The vehicle weight limit on the bridge will be reduced in mid-April from the current 40 tons (80,000 pounds) to 10 tons (20,000 pounds).
