The mayor's office says the storm sewer that collapsed over the weekend is located underneath the walkway connecting the Martin Luther King Jr. Blvd and Wilson Street intersection to Monona Terrace.
Emergency repairs are being coordinated and will take place this week.
The sinkhole is fenced off and fencing installed to identify allowable walk routes.
City staff are working with Monona Terrace as it prepares for a conference this week, assuring guests will have a safe passage into and out of the facility.
Shake the Lake activities will not be affected by the sinkhole.
