Holidaymakers are being warned to plan ahead of upcoming overnight closures on the M56.
Allow extra time for your journey if you have any late-night or early-morning flights from Liverpool and Manchester coming up.
Work begins today (August 15) for eight weeks, with the closures expected in late September and early October.
Road resurfacing, joint repairs and replacement manhole covers all need to be done as part of the £1.5m work.
Each closure between junctions 12 and 14, Runcorn and Hapsford, will stretch from 8pm through to 6am the following morning.
Highways England project manager Mark Mosley said: “These are essential, if routine, wear and tear repairs and will add time to people’s journeys.
“It’s vital people plan their journeys carefully over the next few weeks – especially if they are heading to the region’s two main airports during a handful of overnight carriageway closures.
“We run a very busy schedule of repair, maintenance and upgrading work across the whole network, and unfortunately it isn’t possible to organise everything we do to avoid the holiday season.Bank holiday chaos on the M56 as holidaymakers abandon cars and WALK to airport
“This kind of work, by its nature, also needs to be done during drier periods.”
The planned closures are currently scheduled for September 30 (Friday) and each day from October 3-5 (Monday to Wednesday).
But Highways England said the times could change due to poor weather or other factors.
Either the westbound or eastbound carriageway will be closed off, but not both at the same time.
The Weaver Viaduct carries traffic over the River Weaver near Runcorn at J12.
Traffic will be diverted along the A56 through Frodsham and Helsby when the closures are in place.
Throughout the eight weeks there will likely be single lanes shut which could also cause congestion.
Both Manchester Airport and Liverpool John Lennon Airport have warned passengers to allow extra time to make their flights.
Manchester Airport director of landside operations Wayne Poole said: “Whilst the work is scheduled to be carried out overnight, it is likely to impact passengers travelling to the airport for our first wave of departures early in the morning.
“We’d advise passengers to check the latest travel advice before they set off and allow additional time to make their journeys.”
