Federal Highway 3 (, **Fed. 3 **) is a tollfree part of the federal highway corridors. One segment connects Tecate (and California State Route 188 on the US-Mexico border) to Ensenada in Baja California. This segment ends at its junction with Fed. 1 at El Sauzal Rodriguez, just a little north of Ensenada. This segment of the highway is 112 km long. This segment of the highway is important because it shortens the distance between the Baja California peninsula and the interior of the country by providing a link with Fed. 2 bypassing Tijuana. It also connects Valle de Guadalupe, San Antonio de las Minas and Valle de Las Palmas. A second segment of the highway, 196 km, begins at Fed. 1 in Ensenada and links Ensenada with Fed. 5 near the east coast of the Baja California peninsula. Their junction in the town of El Chinero is 55 km north of San Felipe, Baja California. There is a military inspection station just south of the junction, where all passing vehicles in both directions are subject to search.
