A total of £13.2m was allocated for a host of projects in 2020/21, with a projected £9.9m and £8m more in 2021/22 and 2022/23 respectively.
All three financial years include work to carriageways and bridges, drainage, traffic signals, road restraint systems, footways, cycleways, street lighting, road signs and markings.
According to the local authority’s forward plan - which includes major infrastructure projects for the next 12 months - its highways capital programme for 2022/23 will be formally agreed on March 23.
A report said: “The highway asset is the single highest value asset the council owns. The last reported gross replacement cost for the entire asset was £2.1bn.
“The proposed investment will make it more sustainable in the longer term and provide a better experience for highway users.”
