The B4, or Horner Straße, is situated in the northeastern part of Austria, traversing the Lower Austria region. The road stretches between the vicinity of Zwettl and extends towards the east, passing through a mix of inhabited areas and open countryside. The starting point is located approximately 7 km (4.3 miles) from the town of Zwettl, a settlement known for its historic abbey and picturesque setting. The B4 serves as a connector between several rural communities and is recognized for its accessibility and infrastructure.

The B4 road covers a distance of approximately 21.5 km (13.4 miles), with elevations ranging from 586 m (1,923 ft) to 929 m (3,048 ft). The road surface is asphalt and is generally rated as excellent, providing a smooth and predictable ride. The majority of the route features wide lanes (about 87%), with two lanes being predominant (about 72%), ensuring ample space for overtaking and maneuvering. The road is gently curved, making it suitable for riders who prefer a relaxed journey over highly technical riding. About 53% of the B4 passes through inhabited areas, offering glimpses of local life and easy access to amenities. The maximum speed limits along the route vary between 50, 60, and 70 km/h (31, 37, and 43 mph), depending on the specific section and proximity to settlements.

One of the notable features of the B4 is its proximity to several viewpoints, providing opportunities for riders to pause and appreciate the surrounding landscapes. The region is characterized by rolling hills, forests, and agricultural land, typical of Lower Austria. Zwettl, near the starting point, is home to the Zwettl Abbey, a Cistercian monastery with a rich history dating back to the 12th century. The area also offers access to local hiking trails and rural attractions, making it a suitable base for further exploration. While the B4 itself is not renowned for dramatic mountain scenery, its viewpoints and rural charm contribute to a pleasant touring experience.
