R-13 regional road () is a Montenegrin roadway.
Section from BioÃÂe to Mateà ¡evo is a parallel road to section of BarâÂÂBoljare motorway that was finished in 2022. When this section of BarâÂÂBoljare motorway was finished, R-13 regional road section from Mateà ¡evo to Kolaà ¡in would serve as a major connection from motorway to the highway.
The M-9 highway was officially opened for traffic in 1984. It was built as part of the larger M-9 highway within the Yugoslav highway network, spanning Montenegro, Kosovo and Serbia. It connected Kolaà ¡in and Andrijevica with Peàand Prià ¡tina in Kosovo, and Leskovac and Pirot in Serbia.
The M-9 highway originally flowed through the city of Kolaà ¡in to connect it to the M-2 highway. A bypass was built via the Vladoà ¡ Bridge to merge the M-9 with the M-2. On 27 March 2014, the Ministry of Transport and Maritime Affairs officially realigned the M-9 highway to its current alignment, incorporating the Vladoà ¡ Bridge, while downgrading the M-9's former path through Kolaà ¡in as a municipal road.
In January 2016, the Ministry of Transport and Maritime Affairs published bylaw on categorisation of state roads. With new categorisation, R-13 regional road was created from previous R-19 regional road and section of previous M-9 highway from Mateà ¡evo to Kolaà ¡in.
