The M6 from J13-J15 was meant to have massive progress done this summer. It's already a 60 limit from just north of J14 up to J15, thereby lowering journey times by a couple of minutes over previously. However, this current situation may mean far less work can take place due to social distancing, thereby prolonging the works beyond winter 2021/2022.
That stretch of motorway has been plaqued with problems for many years. The whole M6 corridor through Cheshire & Staffordshire is just horrific - journey times are doubled, there are collisions/incidents everyday and the motorway cannot handle the volume of traffic connecting the Midlands with the North West anymore.
The stretch of the A56 running between the M56 & M6 was turned into a mini motorway about a decade ago to accommodate the rise of traffic commuting from Manchester & the rapidly expanding Airport. However, once traffic reach the M6 they are on a hiding to nothing.
There were plans to turn the whole of the M6 between Birmingham & Preston into a smart motorway which would mean the hard shoulder being turned into a 4th lane at peak times. The whole project would take years & millions of pounds of government money to upgrade.
In light of the economic crisis looming over us all now, its very unlikely any motorway projects like this will be considered in the immediate future.
