Portland Bridges

All clearance above “0″ water (MLLW or CRD datum) – Check NOAA for adjustment to the current Columbia River level or Willamette River level.

When navigating the Willamette River, call the Hawthorn Bridge first as it is manned 24/7 and also can tell you the clearances of the other 3 bridges. Bridges will not be opened during rush hours and you need to call at least 2 hours in advance for an opening on weekdays from 8:00am to 4:30pm, and 4 hours notices at all other times. The Broadway, Burnside and Hawthorn are all manned during the Rose Festival. For further details, check Multnomah County’s Requesting A Bridge Opening.

The bridges’ links are to Wikipedia unless stated otherwise (a good way for visitors to Portland to acquaint themselves with the looks of our bridges).
