Twelve-foot turn and bypass lanes will be constructed at Ivanhoe Street. <br /> <br />Proposed improvements also include a 10-foot bituminous detached trail located on the <br />north side of 175th Avenue. <br /> <br />The proposed street section is shown on Exhibit 2. <br /> <br />3 <br /> <br /> <br />
