Present state of the bridges

Two of the seven original bridges did not survive the bombing of Königsberg in World War II. Two others were later demolished and replaced by a highway. The three other bridges remain, although only two of them are from Euler's time (one was rebuilt in 1935). These changes leave five bridges existing at the same sites that were involved in Euler's problem. In terms of graph theory, two of the nodes now have degree 2, and the other two have degree 3. Therefore, an Eulerian path is now possible, but it must begin on one island and end on the other.

The University of Canterbury in Christchurch has incorporated a model of the bridges into a grass area between the old Physical Sciences Library and the Erskine Building, housing the Departments of Mathematics, Statistics and Computer Science. The rivers are replaced with short bushes and the central island sports a stone tōrō. Rochester Institute of Technology has incorporated the puzzle into the pavement in front of the Gene Polisseni Center, an ice hockey arena that opened in 2014, and the Georgia Institute of Technology also installed a landscape art model of the seven bridges in 2018.

A popular variant of the puzzle is the Bristol Bridges Walk. Like historical Königsberg, Bristol occupies two river banks and two river islands. However, the configuration of the 45 major bridges in Bristol is such that an Eulerian circuit exists. This cycle has been popularized by a book and news coverage and has featured in different charity events.
