The Baltic Way will cover the Vilnius-Panevezys road stretch between kilometers 9 and 13.2, and the Panevezys–Pasvalys–Riga road stretch between kilometers 4.6 and 66.
"By naming the roads after the Baltic Way, we will mark this significant and exceptional event in the history of Lithuania," Transport Minister Jaroslav Narkevic told the Cabinet.
Deputy Transport Vladislav Kondratovic told BNS last month that Latvia and Estonia would be invited to commemorate the event in the same way.
Narkevic said on Wednesday he would discuss the initiative with his Latvian counterpart on Saturday.
On August 23, 1989, over a million people formed a human chain spanning Lithuania, Latvia and Estonia to demand an end to the Soviet occupation of their countries.
The Baltic Way has become a symbol of non-violent liberation elsewhere in the world.
In 2004, people in Taiwan joined their hands to protest against China's military treats, and the Catalans seeking independence from Spain did the same in 2013. Last year, thousands of people in Hong Kong formed a 40-kilometer human chain to protest against China's interference.
