● History

The D1 road has a long history, dating back to the Austro-Hungarian Empire, when the road was built as a major transportation route between Zagreb and Ljubljana. During World War II, the road was an important supply route for the Axis powers, and it was heavily damaged during the war. After the war, the road was rebuilt and upgraded, with the construction of new bridges and tunnels, such as the Macelj Tunnel. In the 1990s, the road was again damaged during the Croatian War of Independence, but it was quickly rebuilt and upgraded, with the help of international organizations, such as the European Union and the World Bank. Today, the D1 road is an important part of Croatia's transportation network, with plans for further upgrades and expansions, including the construction of new highways, such as the A2 (Croatia).

● Traffic Volume

The D1 road is a busy transportation route, with a high volume of traffic, particularly during the summer months, when many tourists travel to Croatia's coastal regions, such as Istria and Dalmatia. The road is also an important route for trucking companies, with many trucks transporting goods between Croatia and other European countries, including Germany, Austria, and Italy. According to data from Hrvatske ceste, the D1 road carries an average of over 10,000 vehicles per day, with peak traffic volumes occurring during the summer months, when the road is used by many tourists and trucks. The road is also used by many buses and coaches, operated by companies such as FlixBus and Eurolines, which provide connections to other parts of Croatia and neighboring countries, such as Slovenia and Bosnia and Herzegovina.

● Junctions and Interchanges

The D1 road has several important junctions and interchanges, including the Bosiljevo interchange with A1 (Croatia), which provides a connection to the Adriatic coast and the city of Split. The road also intersects with several other important roads, including the D3 (Croatia) and the D6 (Croatia), which provide connections to other parts of Croatia and neighboring countries, such as Bosnia and Herzegovina and Serbia. The D1 road also has several traffic circles and intersections, which provide access to local roads and communities, such as the Krapina and Varaždin cities. The road is also equipped with several rest areas and service stations, operated by companies such as OMV and INA, which provide amenities and services to drivers, including food, fuel, and accommodation.

● Upgrade Plans

There are plans to upgrade and expand the D1 road, including the construction of new highways, such as the A2 (Croatia), which will provide a faster and more efficient connection between Zagreb and Ljubljana. The upgrade plans also include the construction of new bridges and tunnels, such as the Macelj Tunnel, which will improve the safety and efficiency of the road. The plans are being implemented by Hrvatske ceste, in cooperation with international organizations, such as the European Union and the World Bank. The upgrade plans are expected to improve the road's safety and efficiency, reducing travel times and increasing the road's capacity, which will benefit both domestic and international traffic, including tourists, trucks, and buses. The plans will also have a positive impact on the local economy, by improving access to markets and tourist destinations, such as the Plitvice Lakes National Park and the Rastoke village.
