UPDATE 4:15 p.m.
Here's what we know from M.U.D:
M.U.D. crews are on scene of a 16-inch water main break at 42nd and Marcy Streets. Water has been shut down and approximately 75 customers are affected.
The rear portion of a M.U.D. crew truck sank into a void under the pavement.
Once power lines are turned off in the area, two tow trucks will extricate the truck and crews can begin repairs on the main.
Main repairs are estimated to take from 6 to 9 hours. Once the water main is repaired, M.U.D. will turn the site over to the City of Omaha to make road repairs.
The cause of the break is under investigation.

A little after noon, authorities received calls about a water main break near 42nd Street and Marcy Streets. It's causing traffic around the UNMC/Nebraska Medicine campus to be diverted.
The water weakened the street enough that a crew from MUD had their truck sink into the street as they were trying to repair the break.
According to 3 News Now staffers on the scene, homeowners in the area are taking steps to protect their properties from flooding as water pours into the street.
This is a developing story and we'll provide updates when more information is available.
