Before World War I, there were few isolated routes suitable for transit traffic e.g. present-day A12 highway, connecting Riga with Kaliningrad, or present day A6 highway which was part of highway Warsaw-Saint Petersburg that ran through Kaunas. After Lithuania becoming an independent country in 1918, there was increased demand for new highways for inner needs. First long-distance highways built exclusively by Lithuanian Government were opened in late 1930s. These are following:
Samogitian highway – old highway built in the course 1930s, connecting Kaunas and Klaipėda. Road section between Kaunas and Ariogala is now completely refurbished to motorway, and the road section from Ariogala to Klaipėda is serving as alternative road for a parallelly-built motorway A1 and connects local towns such as Ariogala, Raseiniai, Rietavas.
Aukštaitian Highway – old highway built in the 1930s. It connects Kaunas, Kėdainiai, Panevėžys and Biržai to Riga. After building an original route, new routes were built through the course of Soviet Union and after its dissolution. The road was gradually rerouted to avoid larger urban areas, and now runs from Sitkūnai, bypasses Kėdainiai, Panevėžys, Pasvalys, Biržai, and reaches Latvian border to Riga. Rerouted highway now forms part of Via Baltica.
