In this section of the road, a comprehensive reconstruction was carried out to improve traffic safety, ensure smoother traffic flow, and provide safe conditions for both vehicles and wildlife migration. The existing two-lane road was upgraded to a four-lane AM category motorway, significantly improving travel conditions and enabling safe and comfortable long-distance travel.
Project Solutions:
- Road Reconstruction and Expansion:
- The old, worn-out, and unsafe road was rebuilt into a four-lane motorway (AM category), which significantly improved traffic conditions, increased capacity, and reduced congestion.
- Connector roads were constructed to accommodate local traffic, allowing residents safe and convenient access to the main routes.
- Intersection Upgrades:
- At-grade intersections were removed and replaced with a grade-separated interchange and a tunnel viaduct, greatly enhancing safety and reducing the risk of accidents.
- Wildlife Migration Measures:
- A green bridge (wildlife overpass) was built to allow animals to safely cross the motorway, minimizing wildlife-vehicle collisions.
- Protective fencing was installed along the entire road section to prevent animals from entering the roadway at dangerous points.
- Drainage and Irrigation Improvements:
- The drainage system was upgraded to ensure proper water runoff from the road surface, helping to preserve road quality and prevent deformation caused by water accumulation.
- Lighting:
- Intersections were illuminated to improve visibility during nighttime and enhance safety for both drivers and pedestrians.
Project Benefits:
- Safety: Grade-separated interchanges and tunnel viaducts significantly enhance safety by reducing the risk of accidents. Lighting and other safety features ensure better visibility in low-light conditions.
- Environmental Protection: The wildlife overpass and fencing reduce animal-vehicle collisions, helping to preserve biodiversity and improve ecological balance.
- Convenience and Efficiency: The four-lane motorway facilitates better traffic management and reduces congestion, ensuring faster and more comfortable travel. Local access roads improve daily life and mobility for nearby communities.
- Economic Value: The improved infrastructure enhances the transportation of goods and services, supporting regional economic growth and logistics efficiency.
The reconstruction of the A5 Kaunas–Marijampolė–Suwałki road, section from 72.5 to 79.00 km, significantly enhanced both safety and efficiency within the road network. The implemented solutions have reduced accident rates and improved comfort for users, while also contributing to a more sustainable and secure transportation system.
