The crossings that we built under the national road No. 16 in Masuria pass the test. This has been confirmed by monitoring conducted for 3 years. Unfortunately, there are also unpleasant situations. Again, a section of the guiding fences was destroyed. A car fell into a ditch, and the elements of the fences were carelessly broken while pulling it out. The perpetrator could not be identified. The incident probably happened at night, and the driver did not want to deal with the police. We can't help it - we're starting the renovation.
