The Brda river flows at the southern end of the street, where are located one active water lock and the remnant of a second one.

The original wooden lock, known as Śluza Miejska (transl.
 City lock), was built when the Bydgoszcz Canal was put into service in 1774, but was regularly rebuilt:
in 1788, when the lock collapsed;
in 1790, a construction using brick and stone started, but eventually in 1792, a wooden lock was set up again (it collapsed anew in 1803);
another rebuilding happened in 1794;
in the following years, the lock was modernized and repaired many times.

In 1884, a brick lock with an unusual trapezoidal shape was put into force, in order to lessen the stress on the Śluza Miejska.

In 2014, on the occasion of the 240th anniversary of the Bydgoszcz Canal, as part of the restoration of Brda river's edge, the walls and the chamber of this former trapezoidal lock were exposed for educational and historical purposes, the basin being filled with sand.
Nearby, a playground for children and a fountain network have been opened.

In 2005, the city lock ensemble (lock, engine room, control room and lock house) was entered on the Kuyavian-Pomeranian Voivodeship Heritage List (No.601229 Reg.
A/209), 31 March 1931.

In October 2014, a major year-long overhaul of the lock has been performed including the maintenance of walls and bottom of the lock chamber, mechanical elements, slopes, retaining walls, circulation channels, installation of sound and vision monitoring, renovation of access roads and fences.
Eventually, the lock re-entered operational service on April 30, 2016.
