During the French rule, at the beginning of the 19th century, at a time when major public works were started regularly employing prisoners, a bridge across Korana was built in Rastoke, which had an important role in the later development of the magistral road through Slunj.
With the construction of a new magistral road from Karlovac towards the Adriatic Sea, two more bridges were built according to the design of Krunoslav Tonković, the most able Croatian bridge builder, one across Slunjčica and the other across Korana. Massive concrete construction was formed into an elegant link hovering above the canyon and dynamically flattering the nature beauty found there.
St. John of Nepomuk is at the place of the first bridge across the Slunjčica river, dating back to 1825, the construction of which made the road from Karlovac through Slunj and further to the south of a magistral character, attracting new inhabitants, while Rastoke became an important milling centre. According to the common habit in Central Europe at the time, the seat of St. John of Nepomuk was built onto the bridge in 1886.
Moćan’s bridge as a picturesque wooden bridge on concrete pylons can be found beneath the Old Town of Slunj. It is one of the first, very rare and significant examples of bridge building from the first third of the 20th century in Croatia; it was renovated in 2015.
