Until 1999 it was a single carriageway that, especially during summer time, made driving to the south east part of the island a bad experience.
In 1999 the first part of the road from the city to Faliraki was expanded to a dual carriageway with 4 lanes and jersey barrier island.
From there up until Exit 21/Kolympia is dual carriageway with speed limits varying due to passing within residential and tourist areas.
From Kolympia to Lindos the road becomes single carriageway making junctions hard to record, as every 50 or 100 metres one exists.
The main junctions of the road are (Rhodes City to Lindos direction): In June 2018 South Aegean regional governor announced that further widening of the avenue from Kolympia to Lindos is back on track as a works prestudy and an environmental study were finally submitted for approval and estimating that by 2019 June the complete study will be ready in order for funds to be allocated and proceed with a tender.
