The entirety of the R300 Freeway is part of the proposed
Peninsula Expressway, which is to be designated as the N21 and is to be a
toll road. This new national route is to include the current R300 freeway as well as extensions at either end of that R300 freeway. The proposed road is meant to extend the current R300 from its northern terminus (Stellenberg Interchange) with the
N1 highway, past
Durbanville, bending west, up to the
Melkbosstrand and
Blouberg coastal area. It is also meant to extend the current R300 from its southern terminus (
Mitchells Plain) junction with the
M7 route (Jakes Gerwel Drive) westwards, through
Zeekoevlei, up to the
Muizenberg and
Westlake area. ==References==
