Drivers travelling westbound on the M62 near junction 34 Whitley Bridge turn off are advised to allow extra time due to essential roadworks.
Works are taking place to repair a section of the motorway which has been affected by mining subsidence.
For safety reasons, lanes two and three on the westbound carriageway are closed while engineers look into the cause of the subsidence and investigate solutions to fully reopen the carriageway as soon as possible.
Highways Agency project manager, Steven Wright, said: “Unfortunately, ground conditions have caused a sudden deterioration in the structure of the carriageway and we have to take action to ensure the ongoing safety of road users. By later this lunch time we hope to open the hard shoulder to drivers to increase the capacity of the westbound carriageway and minimise the disruption to drivers. For safety reasons a 50mph speed limit will be put in place.
“We regret any inconvenience this essential work is likely to cause to drivers in the area but it is paramount that we ensure the safety of the travelling public.
“At this time we are not able to determine when the carriageway will be fully reopened as this is dependent upon the results of the investigation work. We will keep drivers updated once we know more details. We encourage all drivers to drive carefully through the roadworks, keeping within the speed limit, and concentrating on the road ahead.”
