A section of the M56 will be closed in both directions over the coming weekend to allow for a new bridge to be lifted into place.
Drivers are being warned to avoid the Runcorn stretch of the highway in both directions between junctions 11 and 12 as the new 67 metre-long bridge is installed. National Highways say clearly marked diversions will be in place during the work, which is expected to take a full weekend to complete.
Delays are expected, and motorists are advised to allow extra time for journeys on this route.
