The comparative evaluation of a roundabout with a signalized intersection on Highway 117 in Val-d'Or was undertaken for the Quebec Ministry of Transportation. Safestreet also provided designs to improve both options, most noticeably an innovative central island in the form of a half cercle to allow the passage of oversize trucks. This resolved the controversy that had erupted, allowing the Ministry of Transportation to open the first roundabout on its own network of highways.
