The Gautrain Rapid Rail Link is a modern rapid rail network for Gauteng that will be extended in the future. This investment in the future of the Province and South Africa, will link Tshwane, Johannesburg and OR Tambo International Airport. There will be 10 stations linked by 80 kilometres of rail, which will allow urban commuters to travel safely at high speed (160 km/h) between centres.
The Gautrain crosses the N14 Freeway in Centurion at Jean Avenue and runs parallel to the Freeway past Trichardt Road. The northbound on and off ramps at Trichardt Road were in conflict with the Gautrain alignment and needed to be closed. A new half interchange was therefore constructed at the K103 (M10 Wierda Road) cross road.
The project involved a detailed survey of all existing road signs related with the relocation of the northbound intersection. A total of four roads were involved with this change, the N14 northbound, the K103 (M10 Wierda Road), the M24 Trichardt Road and the R101 Old Johannesburg Road.
A total of 50 Road Signs were involved in the survey of which 15 could be retained, 16 new signs are needed, of 8 signs the text needed modification, of 3 sign an extra panel was added and 15 signs could be removed. Of all the new signs and signs that needed modification a detailed manufacturing drawing was supplied.
