A weekend closure on the M6 in Cheshire has been delayed for a week due to a cold snap.
The first of two weekend closures at junction 19, Knutsford, was due to take place this weekend but will now begin on Friday, January 22.
Highways England was meant to be installing a bridge beam across the carriageway as part of a £43 million improvement scheme.
But a drop in temperatures meant there was not enough time to complete the support columns in the hard shoulder and central reservation.
It means work cannot begin on Friday as expected.
A Highways England spokesman said: “The two Friday night to Monday morning closures will now take place on the weekends beginning Friday 22 January and Friday 29 January with an operation to crane 36 huge, 90 tonne bridge beams into place over the northbound and southbound carriageways.
“Highways England is constructing a bridge over the M6 through the existing junction roundabout to improve traffic flow between the motorway and the A556 and reduce congestion around the roundabout itself.”
