Engineering and design

The Portland Bureau of Transportation (PBOT) will improve safety on NE Marine Drive from NE 33rd to 185th avenues by laying new striping and pavement markings to increase the visibility of lane limits and installing rumble streets. The changes will reduce crashes caused by lane departures.

Construction planned July - October 2020

Project background and description

NE Marine Drive is one of Portland's High Crash Corridors. High Crash Corridors are streets in Portland with a high concentration of crashes. 

  • The fatality rate on NE Marine Drive is substantially higher than the citywide rate. On average, for every 1,000 crashes in Portland, three result in a fatality. However, out of 1,000 crashes on Marine Drive, 28 result in a fatality.
  • The percentage of crashes that occur when a vehicle goes outside of its travel lane (e.g. head-on crashes, sideswipes, roll-overs, hitting fixed objects) along Marine Drive is three times higher than the citywide percentage (19% versus 5.5%).

Open stretches of roadway, clear sight lines and few intersections are all characteristics that may contribute to the high percentage of lane departure crashes.

  • DUII Crash Rate: The incidence of crashes involving DUII is slightly higher than the citywide average.
  • Speeding: About 7% of drivers are driving 10 mph or more over the posted speed limit.
  • Marine Drive is not a designated truck route, yet trucks make up 16-22% of traffic. In comparison, nearby NE Columbia Blvd is a Priority Truck Street and carries 17-18% truck traffic.
