The E45 was to be widened due to increased traffic on the stretch and the Road Directorate wanted a smooth process with minimum disruption to traffic during construction. Therefore, during the first stage in 2017, the emergency lanes on both sides were first upgraded to carry the necessary heavy traffic during the extension of the third lane in the central reservation. The extension with the third track was carried out in 2018 as stage 2. Stage 3, which was the last stage of the extension, was a straightening of the road's longitudinal profile to ensure better driving comfort and reduce rolling resistance and fuel consumption. This was done using "3D" milling a special equipment, but at the same time it caused varying thickness in the existing asphalt pavement layers. The solution was reinforcement under the asphalt overlay.
