            2019 | Oval shaped. ICD = 90 ft x 82 ft. Protected/separated bicycle lanes and separated bicycle-pedestrian crossings. Pedestrian buffer strips only along part of sidewalk between crosswalks. The roundabout was a conversion of an existing intersection. Some corners of the intersection don't have full concrete separators due to right of way constraints. The one separator geometry was based on a sewer air release valve manhole that couldn't be lowered. The center island is slightly oval shaped; earlier concepts had a round center island. The approaches use a zicla barrier. The artwork was added later. |
