It comes two months after The Scotsman highlighted the country’s motorways were in a worse condition and deteriorating faster than other roads.
The work, between now and March, will cover 25 roads including the M8, M9, M90 and M74.
Other trunk roads to win repairs include the A82, A90 and A77.
Repairs will also be made to the carriageway of the 80-year-old Kincardine Bridge over the Forth.
The Scottish Government’s Transport Scotland agency, which is responsible for trunk roads, aid the spending was being targeted “at the sections of the network that need it most”.
A spokeswoman said: “The additional resurfacing to address wear and tear will address potholes and reduce the need for more expensive and disruptive major maintenance at a later date.”
The proportion of motorways which need resurfacing increased from 30 to 42 per cent in three years, according to figures from public spending watchdog Audit Scotland published in August.
By contrast, the figure for other roads - which are maintained by councils - remained unchanged at 37 per cent.
Motorways have been historically the country’s best-maintained roads, but the watchdog’s report said less was being spent on them, with more patching work rather than more significant repairs.
It said Transport Scotland had cut spending on trunk roads by 4 per cent to £162 million over the three-year period between 2011-12 and 2014-15.
Mr Yousaf said today: “While our trunk routes remain in overall good condition, it is clear that extra investment could make further improvements.
“Careful thought has been given about how to get the most out of this new funding, and it is being used on projects that will help prolong the life of the network.”
