The Oregon Department of Transportation is prepping for an inspection project on the St. Johns Bridge. The project will close the bridge at night for a week starting Monday, February 1st. Work is scheduled for completion by Saturday, February 6th.
The bridge will be closed to driving traffic from 10:00 pm to 5:00 am for the week; but ODOT will keep one sidewalk open at all times for bicycling and walking traffic.
As you can see in the photo below, the sidewalks on the St. Johns Bridge are quite narrow, so if you use it next week during closure hours, be prepared for close passes with other users. More info via ODOT website.
