M13 (Durban)

The M13 is a metropolitan route in the Ethekwini Metropolitan Municipality in the KwaZulu-Natal province of South Africa. For most of its route, it is a highway named King Cetshwayo Highway and it acts as an alternative route to the N3 highway for travel between the suburbs closer to the Durban CBD and the Outer West Suburbs.

Route

The route starts in the Durban Central Business District at an intersection with the M4. For the first few kilometres of its length, it runs parallel to the N3 on both sides as King Dinuzulu Road North and King Dinuzulu Road South. At the Tollgate Bridge, it then turns to the south and passes westwards through Mayville, before turning north and crossing under the N3 to pass through Sherwood.
At 45th Cutting, the route becomes a dual-carriageway freeway and remains as one for the rest of its length. The route passes over the N2 highway westwards as a flyover and passes through Westville and Cowies Hill. The route then briefly touches the N3 at the Paradise Valley interchange, before passing west-north-west through Pinetown.
After Pinetown, the route goes up Fields Hill, a 3 km 1:15 gradient. The route then enters the Upper Highway Area, passing westwards through Kloof and Gillitts, before the R103 diverges, providing access to Hillcrest. The route then passes south of Hillcrest and through Assagay before merging with the N3 freeway at the Key Ridge Interchange, where it ends.
The route is roughly 35 km long.

Significance

The M13 is the main thoroughfare to Durban for residents of the nearby towns of Westville, Pinetown, Kloof, Gillitts and Hillcrest.
The M13 between the Paradise Valley interchange and its termination at the N3 used to be part of the N3 route until 1986, when the N3 was re-routed to pass south of Pinetown, Westmead and Winston Park. The M13 remains an alternative route to the N3, and is commonly used by motorists wishing to avoid the Mariannhill Toll Plaza, located on the N3 outside Westmead.
