Transmission Gully is the name of a massive road-building project, involving the construction a 4-lane motorway between Paekakariki and Porirua in the Wellington area, New Zealand. Controversial due to its high cost, environmental implications, the challenging terrain and the earthquake-prone route, it has been promoted as a road that will provide less-congested access into Wellington as well as an alternative to the three main ways into the city, all of which might be cut off in the event of a severe earthquake. The road is expected to be completed in 2020.
The project was officially started on the 8th September 2012, although work didn’t begin on the route for some months. However, this date was marked with a ‘turning the sod’ ceremony by the then-Prime Minister John Key. Photo records show this to have taken place at 1:41pm, just outside Paekakariki, and the chart below is drawn for this moment.
What might we expect to see from such a chart?
