Motorists are facing disruption in Cheshire after part of a motorway was closed because pools of water from a burst pipe froze on the surface.
The M53 was closed in both directions between junction five and seven after police said conditions were "too dangerous" for drivers.
Cheshire Constabulary advised motorists to avoid the area and said there were potential delays in traffic.
Diversions have been put in place while engineers investigate the leak.
A spokeswoman for Cheshire Police said: "We are advising motorists that there could be potential delays in traffic this morning and to plan extra time for their journeys."
The spokeswoman said pools of standing water had turned to ice across the motorway.
Temperatures in the region fell to about -5C overnight.
"The conditions are too dangerous for drivers and whilst the burst water main is being investigated and dealt with by utility companies the motorway has been closed," the spokeswoman added
"Diversions have been put in place. If you can avoid the area between junction 5 and 7 we are asking drivers to do so."
If motorists cannot avoid the area, the spokeswoman advised them to delay their journeys. THE BBC
