It happened just north of 24th Avenue.
Part of the eastern wall of the creek crumbled into the water, along with the soil and grass on the other side.
The city hired a contractor to temporarily fix the problem, but it highlights the immediacy of an issue the city has been working on for some time.
“The longer-term solution is a big question, it’s probably a very expensive question, and it involves the habitat, flooding control, it’s a big picture thing and we’re only dealing with an emergency repair today,” said Eric Jones, Eugene Public Works Manager.
The bike path wasn’t damaged but will be closed for repairs Monday and Tuesday this week between 24th and 19th avenues.
