Half of all roads across Yorkshire and Humberside are at risk of failing by 2039 according to the new ALARM report.
The annual report from the Asphalt Industry Alliance surveys local authorities on road maintenance and funding and found that the current backlog of repairs alone would cost £1.5 billion to complete.
45% of local authorities reported that their highway maintenance budget had been cut or frozen in the past year.
The report also found the average highway maintenance budgets of authorities had increased by 2.3% over the year.
AIA Chair Rick Green said: “Local authorities in Yorkshire and Humberside have a bit more money to spend this year but the impact of rising costs due to inflation means they have actually been able to do less with it.
“Couple this with the effects of the extreme weather we are increasingly facing, and the result is that the rate at which local roads are suffering is accelerating towards breaking point.”
However, a spokesperson for the Department of Transport said: “We’re taking decisive action to resurface roads and fix potholes by investing an extra £8.3 billion into the biggest ever funding increase for local road improvements.
“This includes £991 million of funding to resurface roads across Yorkshire and the Humber.”
The funding increase was announced in October 2023, reallocating funds from the scrapped HS2 extension beyond Birmingham.
