A roundabout on the M6 will be closed overnight every weekday until November.
The closure comes as the opening of a new £43m bridge at junction 19 near Knutsford is delayed.
It had been hoped that the project would be finished by the end of August.

But further closures are required to enable work to continue.
The roundabout at junction 19 will be closed overnight.
The new bridge is being installed to ease congestion and improve traffic flow on the motorway slip roads and on the A556.
Delays to the project were put down to 'industry-wide product shortages' and the impact of Covid restrictions, with workers having to isolate.
National Highways said: "There will be total closures of the M6 junction 19 roundabout between 9pm and 6am every Monday to Friday until completion of the project in November.
"All approaches to the roundabout will be closed.
"There will be no access to, from or across the M6 motorway at junction 19.
"Motorway traffic will continue to run from junction 18 to 20, in both directions.
"A556 will be closed in Tabley, northbound from A5033 junction and southbound from the M6 junction 19 roundabout.
"A556 will be closed southbound from Bucklow Hill to the junction 19 roundabout.
"M56 junction 7 westbound exit slip road will also be closed with a diversion to junction 10 and back."
