A bypass is a road or highway that avoids or "bypasses" a built-up area, town, or village, to let through traffic flow without interference from local traffic, to reduce congestion in the built-up area, and to improve road safety. A bypass specifically designated for trucks may be called a truck route.
In the picture, the bypass section called Paasikiven–Kekkosentie of the Highway 12 bypasses the city center of Tampere in Pirkanmaa, Finland. Highway 12 was moved between Santalahti and Naistenlahti to the Tampere Tunnel in 2016.
