Lane and turning restrictions on portions of Saddle Creek Road and Emile Street are likely to continue into next week.
While working to repair road damage caused by a water main break Saturday morning, city crews discovered further undermining of the streets.
Saddle Creek Road is down to one lane in each direction from Leavenworth to Farnam Streets.
There will be no left turns from Saddle Creek, and it is advised the road be avoided during peak times for the next few days.
