Oregon 99E (McLoughlin Boulevard) is an urban arterial with a posted speed limit of 40 miles per hour. It is a major connection between the Portland metro area and other cities/communities to the south including Milwaukie and Gladstone. Much of this route includes two lanes in either direction with a center lane.
The corridor ranks in the top 5% of the Safety Priority Index System sites from 2020-2022, with a history of frequent turning, rear-end, angle, pedestrian/cyclist and red-light running crashes. In addition, the distance between existing enhanced crossings is more than 1,500 feet away, resulting in out-of-direction travel for road users not in a personal vehicle.
ODOT will install four new rectangular rapid flashing beacons with median islands, new lighting, fill in sidewalk gaps and upgrade existing traffic signal heads along the corridor.
