The R487-million upgrade of a section of the N1 between Plattekloof road and Old Oakinterchange, in the Western Cape, is 60% complete. The project is expected to be completed by May 2019. About 120 000 vehicles travel on this stretch of road during the morning inbound and afternoon outbound peak periods. The addition of a third lane in both directions will significantly reduce traffic congestion on the road once the project is complete.
Work on installing the Freeway Management System, fibre-optic bank and Wemmershoek pipeline is complete, as is work on the concrete retaining walls, the Old Oak inbound on-ramp temporary bypass and the Phase 1 widening of the third lanes in the median.
The Old Oak inbound on-ramp is also complete and open to traffic. Current work in progress includes pavement rehabilitation on the N1 carriageways, which will be completed in October; Phase 2 median widening and installation of the concretemedian barrier, which is 75% complete; Phase 3 median widening and barrier, which recently got under way; and inbound auxiliary lane widening between Durbanroad and Jip de Jager drive, which is 50% complete.
New lanes have been marked between the Old Oak off-ramp and the R300 to reduce congestion while construction is under way. Daily closures are required on the main carriageways for removing existing surfacing and laying new ultrathin friction course surfacing.
