Tenth Line Road

Tenth Line Road (Ottawa Road #47) is a designated arterial road that stretches for 9.5 km in Orléans, Ontario. Its northern terminus is at Jeanne d'Arc Boulevard in Ottawa's east end. From there, it intersects or crosses with roads such as Regional Road 174, St. Joseph Boulevard, Innes Road, and further south into the rural areas of Ottawa across Navan Road. Tenth Line's southern terminus is at Smith Road, southwest of the Navan community.

Tenth Line Road has many commercial areas, housing developments, a high school, a recreational complex, and restaurants located along its north/south trajectory.

In 1993, a small portion of Tenth Line Road was realigned near St. Joseph Boulevard. The re-alignment was placed slightly to the west. The old portion was kept and renamed Old Tenth Line Road which connects to a Highway 174 exit ramp.
