The bridge is commonly cited as the highest narrow-gauge railway bridge on the European continent.
It was originally part of a 17-kilometer narrow-gauge track connecting Koronowo with Tuchola.
The structure's construction utilizes a distinctive lattice steel design typical of early 20th-century Prussian engineering.
The bridge crosses the Brda river at a point where the valley banks are exceptionally steep and deep.
Due to the structural condition of the old sleepers and tracks, the bridge is officially restricted to pedestrian use.
The line was part of a larger network built to facilitate the extraction and transport of timber from the surrounding forests.
The narrow-gauge railway bridge over the Brda in Koronowo is recognized as one of the tallest narrow-gauge railway bridges in Europe. Constructed in 1909 as part of the Koronowo to Tuchola line, it spans 140 meters across the deep valley carved by the Brda River. The steel structure sits at a height of 38 meters above the river level. The bridge served as a key infrastructure point for the regional timber and agricultural industry for decades. Passenger rail traffic on this line ceased in the 1960s, followed by the closure of freight traffic in the 1990s. The structure is currently disused for rail transport and functions as an industrial monument and a pedestrian vantage point. It is situated within the dense forested terrain of the Tuchola Forest buffer zone.
The approach path on the north side provides a clear longitudinal view of the steel truss span against the river valley.
Wear sturdy, closed-toe footwear as the path leading to the bridge can be uneven and sandy.
Carry a flashlight if visiting in the late afternoon, as the forest paths nearby lose light quickly.
Bring insect repellent during the summer months due to the proximity to the Brda River.
Do not attempt to walk across the bridge if it has rained, as the wooden ties and metal become extremely slippery.
Open year-round, though access may be hindered by deep snow in winter or overgrown vegetation in summer.
Respect the structure by not climbing on the steel trusses; maintain caution as there are no modern safety railings.
