The Portland Bureau of Transportation will reduce the speed limit on a two-mile stretch of North Marine Drive, between Interstate 5 and NE 33rd Drive, starting Tuesday Sept. 25, from 40 mph to 35 mph.
PBOT won state approval for the change, as part of the City's Vision Zero effort to eliminate traffic fatalities and serious injuries, on Aug. 30.
There were 140 reported crashes, including six people seriously injured, on this segment of Marine Drive, where the speed limit will be reduced, from 2012 to 2016, the most recent five-year period for which data are available.
The Speed Safety Camera on eastbound NE Marine Drive, which were installed in February, will issue warnings starting Tuesday for two weeks. Citations will resume Oct. 10.
The goal of the Speed Safety Camera program is to reduce speeding and save lives. Marine Drive is one of 30 streets that comprise Portland's High Crash Network. The roads in this network make up just 8 percent of Portland streets, but account for 57 percent of fatal crashes citywide.
The cameras are located in two locations on the corridor – westbound near NE 138th Avenue and eastbound near NE 33rd Avenue. The speed limit is not changing near the NE 138th Avenue cameras, so enforcement there will not be effected.
In addition to the new speed limit, PBOT is delivering a variety of safety projects on Marine Drive including several in East Portland. Slated for construction starting in early 2019 on Marine Drive:
- Shoulder and centerline rumble strips* (NE 33rd to NE 185th)
- New traffic signal at NE 122nd
- Buffered bike lanes (NE 112th to NE 122nd)
- Gaps filled in multiuse path (NE 112th to NE 185th)
- Rapid flashing beacons (NE 112th and NE 138th)
*19% of crashes on Marine Drive are lane departure crashes where a person drives out of their travel lane. On average, centerline rumble strips reduce all crash types by 9% and head-on or sideswipe crashes (which are often serious) by 44%. On average, shoulder rumble strips reduce crashes by 36%.
