Watch time-lapse footage which captured the demolition of the Old Oak bridge below.
The N1 has been re-opened after one bridge and the rubble was removed on Saturday.
Cape Town Freeway Management deployed a mobile CCTV site to monitor the demolition of the Old Oak bridge. The image was displayed above and was updated every 5 minutes.
An engineer working for Western Cape government explained the bridge needed to be demolished to make way for additional lanes.
The bridge at the Old Oak turn off, which was built in 1963, was demolished on Friday evening.
Chief engineer Simon Blyth explains: "In order to add additional lanes to the area on the N1, it was necessary to remove the columns holding the bridge up. The bridge was also too long."
The N1 was to be closed from 19:00 on Friday 12 May and was set be to re-opened on Monday at 05:00, but has been re-opened due to early completion.
You can also access the image and the rest on the network via the I-Traffic Website.
