NIP, sorry.........

You do need to check out exactly where, and what limits were there last week.

 

OS maps and Google Street View for a mile or so in both directions along the A5 from the Halton roundabout show a single carriageway (part with 3 lanes) with derestricted signs. In one direction there are lamp posts but still with occasional derestricted signs.

That I believe, means 60mph. However, Street View was photographed in the autumn of 2018.

 

A thought - you say you are a courier. Was your vehicle subject to speed limits lower than for private cars?

For example, non car based vans over 2 tonnes laden weight have a 50mph limit on single carriageways - as does anything towing a trailer.

 because my side became a dual after the roundabout,

 

You can't have a dual carriage way on one side!

 

On Street View there is no dual carriageway there, only a single carriageway with white lines separating traffic directions. Maybe things have changed since their photographs of 18 months ago.

 

Even with two lanes in a direction it was still a single carriageway as there was no physical separation of traffic directions

 

Others will clarify exactly what defines a dual carriageway in terms of barriers, kerbs, central reservations, signeage, etc but it's not white lines alone.
