Tidal Flow in Bogotá
I found myself on the carerra septima this afternoon in Bogotá just shy of 5 p.m. (having just consumed a wonderful dish of la posta negra de Cartagena at the Club Colombia, watched the Netherlands defeat Uruguay, and had a cup of tea from coca leaves to counter the effects of altitude sickness — it seemed to do the trick). In any case Carerra 7 is one of the city’s principle arteries, multiple lanes divided by an island. At 5 p.m., though, something curious happens on this street: It turns into a massive one-way boulevard out of the city, and towards the north. This is an old and much-discussed idea — contraflow lanes — one that was practiced briefly in cities like Los Angeles and made a splash recently in emergency management circles for mass disaster evacuations.
But it was striking to see it in action. At just the stroke of 5 our car was still on 7, and there was already a small stream of vehicles beginning to seep across from the other lane. Their movement was cautious, exploratory, with the first vehicles coming across employing their hazard flashers. Their numbers began to surge, and it was immediately evident that staying on 7 was not prudent. There were one or two traffic police scattered about, and there are signs advising of the change, but one got the sense this was just a bit of ingrained civic behavior, as routine as the clock itself.
