R101 (Western Cape)

The R101 is a regional road in South Africa that is the designation for old sections of road that were previously the N1, prior to upgrading.

The R101 begins in Bellville at the R102 and runs to the south parallel to the newer N1 freeway and is called Old Paarl Road. It crosses the Drakenstein Mountains as Du Toitskloof Pass (820m) where the new route bypasses as the Huguenot Tunnel. Through the pass it rejoins the N1 for 8 km until it separates again towards Rawsonville until it joins the N1 again at Worcester. The R101 does not separate from the N1 again up to Kroonstad in the Free State more than 1000 km to the north-east.

A section of the R101 in Gauteng and Limpopo provinces connects Johannesburg with Polokwane via Pretoria and Bela Bela. The first part connects Johannesburg and Pretoria. It begins at Louis Botha Avenue (forming part of Johannesburg Metropolitan Route M11), intersects with R55, and continues as Pretoria Main Road (later Old Pretoria Main Road), passes through Midrand, and becomes the Old Johannesburg Road in Centurion, later changing names again to Jan Smuts Drive in Pretoria, where it merges with the endpoint of the N14 Ben Schoeman Freeway at Potgieter Street.
