According to the article below, this was converted from a rotary to roundabout in 2011 (but no apparent geometric changes). https://ici.radio-canada.ca/nouvelle/682505/carrefour-rond-point-sept-iles [Translation note: French has two terms for circular intersections: rond-point and carrefour giratoire. According to the article, the former term means rotary (traffic in circle yields) and the latter means roundabout (entering traffic yields). However, Google Translate translates them both as 'roundabout', making for a confusing article if you don't refer back to the original French.] ICD estimated from Google Maps linework. | |
