In 1978, Government of Pakistan (GoP) decided to Federalize five important Inter-Provincial Roads named “National Highways” and created the National Highway Board for Monitoring the development and Maintenance of these Federalized Roads by Provincial Highway Departments.
The National Highway Authority (NHA) was established, in 1991,
through an Act of the Parliament, for Planning, Development, Operation, Repair
and Maintenance of National Highways and Strategic Roads specially entrusted to
NHA by the Federal Government or by a Provincial Government or other Authority
concerned. Total length of the Federalized Roads under NHA now stands at 8780
KMs, account for 3% of the entire Road Network and 75% of the Commercial Road Traffic
in the country.
