This project includes some 4km of experimental road surfacing with ultra thin continuously reinforced concrete. Consisting of a specialised mix of silica, cement, steel and polypropylene fibres, 6,7mm concrete stone and plasticisers, this 50mm concrete layer has an estimated compression strength of between 90 and 120Mpa.

The toll-highway project included the construction and upgrade of roads and associated infrastructure on:
▶ certain portions of the N1 between the R300 and Sandhills, and on the N2, in the Western Cape;
▶ the construction and upgrade of portions of N1/N2;
▶ the upgrade of the second bore of the Huguenot tunnel;
▶ the construction of toll plazas between the R300 and Bot river;
▶ and the construction of the new, closed ‘cut-and-cover’ tunnel alignment through Helderzicht, extending west from the Danie Ackerman Primary School to the Victoria street interchange.
