The main road in Embrun is Notre-Dame Street (County Road 3). This busy street travels east–west across Embrun, linking its neighbourhoods together. At its western end it connects to Castor Street in neighbouring Russell, while its eastern end travels to the nearby village of Casselman, located 12 km to the east. As Embrun grows, the street has experienced significant congestion. Part of this is aggravated by the fact that, with the exception of a 1 km section in western Embrun which has a centre turning lane, the street is still a conventional two lane street. The municipality has studied the possibility of widening the entire stretch of the street to two lanes in each direction with a centre turning lane, however the cost of this is seen as prohibitive, so instead, the municipality has focused on projects to make traffic flow more efficient. This included the upgrading of intersections, including the installation of new left-turn signals at two intersections (completed in 2011) and the replacement of another intersection with a roundabout (completed in 2012).
