The Seefelder Straße (B 177) runs over the Seefeld Saddle. It approaches from the southeast from Zirl in the Inn valley (with a junction at Innsbruck with the A12 or B 171) over the south and east flanks of the Zirler Berg (with a gradient of up to 16%) through Reith and Seefeld and then heads northeast to the village of Scharnitz on the River Isar by the Austro-German border, crossing the Scharnitz Pass, from where it continues in Germany as the B 2 running past Mittenwald via Garmisch-Partenkirchen as far as Gartz (Oder). In the area of the eastern bypass around Seefeld the road reaches a height of more than 1,220 m north of the saddle near the junction of Seefeld-Mitte. At Auland, south of the saddle, the Landesstraße 36 state road branches off the Seefelder Straße passing through Seefeld and heading for Telfs in the Inn valley.
