Conservative-run Essex County Council has increased its funding for road maintenance over the past five years.
The Labour government has also provided councils across the East with a £72m injection for pothole repairs.
Essex County Council spent £64m last year on road repairs and resurfacing, up from £48m from 2020-21. More than 12,000 carriageway defects were fixed in the past 12 months, it said.
The Conservative Party, which runs Essex County Council, said the authority secured record investment for Essex roads.
The Liberal Democrats proposed increasing council tax by an extra 1% and putting £10m into road repairs.
Labour called for an independent inspector to stop poor repair work.
The Green Party has said Essex County Council “is good at inspecting and monitoring, but less good at actually fixing”.
Nigel Farage MP said Reform UK would take fixing potholes “very seriously” and use technology to make more permanent repairs.
