West Burnside Road is expected to remain closed at least through Friday afternoon. The soonest the roadway will be reopened is 4 p.m. on Friday, March 24, after crews work to repair and improve the road after a recent landslide.
Crews may reopen Burnside at 4 p.m. Friday, but the work is weather dependent, so the schedule may change and the closure may last longer.
Crews will make multiple repairs to improve the condition of West Burnside this week. They are repairing two sinkholes and several potholes. They are improving drainage in areas where stormwater was not draining properly into roadside storm drains.
In addition, there are several places where the base underneath the pavement has been compromised and needs to be replaced. When roads need such base repairs, they often appear to have wavy surfaces that distract drives, collect rain and form potholes.
PBOT is also using this closure as an opportunity to replace the top layer of pavement. Repaving the street will prevent potholes from occurring and prevent the need for a more expensive rebuild later on.
"We don't want to have to come back and repair West Burnside again in two weeks,” said Suzanne Kahn, maintenance operations group manager for PBOT. “With a few more days, we can leave the road in condition that will last one more decade rather than a few more weeks."
Crews are assessing what damage resulted from the slide and what stems from poor pavement condition. Crews from Portland General Electric and other utilities have been in the area this week, locating and protecting their infrastructure as PBOT crews dig into the roadway to make street improvements.
The largest landslide to affect a Portland street this winter occurred at about 7 a.m. Wednesday, March 15. The road has been closed since then.
The public should stay away from the area until PBOT crews decide to reopen it. West Burnside is closed to people biking, walking or driving between NW Skyline Blvd and SW Barnes Road, near the Mount Calvary Cemetery. People driving through the area are encouraged to use U.S. 26 or NW Cornell Road as alternate routes, or consider public transit.
A signed detour guides westbound traffic to use SW Skyline to Barnes Road, then to West Burnside. Eastbound traffic is directed to SW Barnes, then SW Skyline before returning to West Burnside.
PBOT crews removed 1,380 cubic yards of debris on Wednesday through Friday. This is by far the largest of the 42 landslides PBOT crews have responded to this winter. A landslide on SW Skyline Blvd in February displaced more than 600 cubic yards of debris.
PBOT crews using 12-yard dump trucks have hauled scores of loads from the site, and forestry crews have also hauled woody debris.
Winter storms and spring rain have taken a toll on hills in the Portland area. PBOT crews have responded to 42 landslides this season, through March 15.
The public should stay away from the area. We ask travelers to observe all street closures and directions by reader boards and flaggers, and use alternate routes if possible.
