In this situation, do the signs notify you of the end of the expressway?

In the video you are driving on a dual carriageway between noise barriers; on both sides of the roadway there are signs D-9 "motorway", and below them signs with the outline of a car crossed out with a red line - D-8 "end of expressway". The signs inform you about the end of the expressway. The answer is: yes.

The Regulation on road signs and signals states that sign D-7 "expressway" marks the beginning or continuation of an expressway, and its end is marked with sign D-8 "end of expressway"; sign D-9 marks the beginning or continuation of a motorway. The expressway symbol is a white outline of a car, and a red line crossing it out means the end - in the same way, D-10 crosses out the motorway symbol, that is, two roadways with a flyover. Here both signs stand together: the expressway ends because the motorway begins at this point. For the driver of a passenger car, what mainly changes is the speed limit - from 120 km/h on a dual-carriageway expressway to 140 km/h on a motorway. The other rules are the same for both roads and continue to apply: no stopping outside designated places, no U-turns, a ban on vehicles that cannot reach 40 km/h, and a minimum distance equal to half the speed in metres.

Legal basis: § 48 para. 1 and 2 of the Regulation on road signs and signals; Art. 20 para. 3 point 1 letter a and b and Art. 19 para. 3a of the Road Traffic Act (Prawo o ruchu drogowym)
