Zimmerman Trail will be closed Wednesday and Thursday this week due to gas line work by the Montana Department of Transportation.
Billings Public Works Director David Mumford said he was informed Tuesday of the need to close the road.
On Wednesday Mumford said MDT was "verifying the location and depth of the gas main that is in Zimmerman Trail."
Mumford said by email that the road was scheduled to remain closed Wednesday and "under worse case in the morning on Thursday."
An electronic road sign was placed at the intersection of Rimrock Road and Zimmerman Trail sometime Tuesday advising drivers of the closure and directing them to use an alternate route.
