As of Monday, May 18, 2026, pavement structure testing will be carried out on the E 661 Gradiška – Banja Luka highway section, specifically on the Glamočani – Mahovljani Interchange subsection, in the direction from the Mahovljani Interchange to Glamočani.

As a reminder, activities preceding the preparation of the pavement rehabilitation project on the aforementioned highway section—namely geodetic surveying and pavement structure testing in the direction from Glamočani to the Mahovljani Interchange—were conducted during March and April.

The testing of the pavement structure from the Mahovljani Interchange to Glamočani is expected to be completed within the next five working days, starting from May 18, 2026. The testing procedure will take place in the driving and emergency (hard shoulder) lanes.

We advise drivers to exercise extra caution when driving on the specified section while these activities are ongoing, and remind them to adjust their speed to the road conditions and comply with the variable message signs (temporary traffic signaling).
