(Portland, OR)  --  Portland's sobering station is shutting down over staff safety concerns.  Central City Concern said in a statement that they're closing the program because it's become too dangerous for staff members.  The organization says the ongoing opioid crisis is partially to blame.  The Central City Concern Sobering Station has been in operation near Northeast Martin Luther King Jr. Boulevard and Couch Street since 1985.  Mayor Ted Wheeler says the city is working on finding a replacement.
