History
The N14 is the only National Route in Gauteng that was not upgraded in 2010 and is the only National Route within Gauteng without a tolling system on its roads. In 2015 - 2017 the Highway was upgraded and re-tarred from Krugersdorp to Diepsloot. In 2017 - 2019 the remaining section will be upgraded to the Brakfontein Interchange upgrading the N14 from 2x2 to 2x3. The upgrades are done by the Johannesburg Roads Agency and the route remains toll-free.
