The project was divided into 3 tasks: 1) Route of the waterway on the lakes pass: Mikołajskie-Tałty by redevelopment of footbridges on Lake Nicholas. 2) Reconstruction of the waterfront of Ryno Lake. 3) Construction of the lock “Guzianka II”, in Rucianem-Nida, connecting Lake Bełdany and Guzianka with J. Nidzki. Task 1 consisted of paving the narrowest part of the trail by rebuilding the footbridge and removing elements of the former bridge limiting the track. The reconstruction included demolition of the existing support structure and construction of a new footbridge, rebuilding existing supports in order to use them for a new construction, lighting and navigation marking of the footbridge. The elevation of the pillar and pylon allows the higher vessels to move freely. Task 2 consists of developing the shoreline of Lake Ryński through: —construction of shore fortifications that prevent erosion of shores, provide access to berths for sailors and accompanying infrastructure, construction of pedestrians for the operation of vessels with resting areas and accompanying infr., which will provide communication to the built ecological mini marina, construction of field stairs and ramps for disabled persons, construction of technical infrastructure (ground lighting, rainwater drainage) serving the waterfront. Task 3 includes the construction of a lock that communicates Lake Bełdany with J. Nidzki’s navigable route, along with avant-ports, control room building, airlock facilities, erection and flooding. The construction of Guzianka II lock also involves the demolition of the existing one and the construction of a new bridge on the Ruciane-Wejsuny road. The project shall be consistent with the objectives of the prior axis. The 6-culture and heritage of the RPO WiM indicated in the SZOOP, as the result will be a modernised waterway, enabling improved water traffic and navigability, thereby increasing the tourist attractiveness of the region’s natural heritage resources.
