CR4 and 9th Line Innisfil Roundabout


The County of Simcoe is constructing a roundabout at the intersection of County Road 4 (Yonge Street) and 9th Line in Innisfil.  The roundabout will have a two lane configuration to accommodate the future widening of County Road 4 to four lanes (two lanes per direction of travel).  Benefits of the roundabout include improved traffic flow, increased traffic capacity, and enhanced safety due to lower vehicle speeds and fewer vehicle conflict points.  The County will be coordinating with InnServices to install water and sewer mains during road construction.
