A £900,000 project to upgrade two motorway bridges which link the M62 to the M6 near Warrington is due to start tomorrow (Thursday).
Contractors for Highways England need to close two slip roads overnight at the junction, known at Croft Interchange, for around three months while essential work takes place to replace the safety barriers and install new lights.
The closures will affect the westbound exit slip road from junction 10 of the M62 onto the northbound M6 at junction 21a along with the eastbound exit slip road from the M62 onto the southbound M6.
The slip roads will be closed between 8pm and 6am, with diversions taking drivers to the next junction to turn around. A 50mph speed limit and narrow lanes will also be in place on the slip roads at other times of day.
