The solution
Tamil Nadu's highways department was spending heavily but thinly. A World Bank transport note says that in 2011-12 it spent $310 million across 2,675 upgrade contracts and about $76 million across 2,672 maintenance contracts, creating high transaction costs and poor economies of scale.
The smarter answer was not simply more budget. The second road sector project introduced EPC lump-sum contracts with 5-year performance-based maintenance for 435 km of highways, shifting design and quality risk toward contractors.
The operating change scaled. By 2017-18, the number of procured contracts had fallen to 878 from 5,347, while about 3,000 km of non-project highways were under performance-based maintenance. The department was managing a 29,000 km network with a $1.5 billion budget and fewer staff than 10 years earlier.
What it achieved
Bundle roads into accountable assets
Why it worked
Bundling gave contractors enough scale to use better equipment and planning.
Five-year maintenance made construction quality matter after opening day.
Fewer contracts reduced the agency's supervision burden and made asset management possible.
What can be applied
Fragmented procurement can make an agency busy but weak; larger output contracts let it manage asset condition instead of paperwork.
Aftermath
The World Bank note says the department mainstreamed performance-based maintenance and paired the contract shift with digitized procurement, HR and financial-management improvements. The broader insight is blunt: a road agency can be too fragmented to be competent, even when it is spending real money.
