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. | |

2014 | All paint, no raised islands. Opened November 2014. Previously, Olympia Park Circle made a gentle 90-degree curve. Traffic entering from stop-controlled driveway had trouble making left turn as they had to proceed 60 feet to reach the safety of centerline without knowing if approaching vehicle on their left was going to enter the driveway or curve left in front of them. Now about 50% of driveway exits cheat across the central island, but it works just fine. After six years with no raised islands, a central island was built on 3 Nov 2020: 20 feet in diameter, 4 inches high, designed for asphalt but built with PCC. |
