Consisting of six lanes, it stretches from Cumhuriyet Boulevard in Çankaya to the İzmir-Çeşme motorway in Üçkuyular, running along the southeastern coast of the Gulf of İzmir.

The route was constructed upon reclaimed land, due to lack of space on the pre-existing coast, and built as a six-lane boulevard.

Considered an urban extension of the Çeşme motorway, the Mustafa Kemal Coastal Boulevard was originally planned to continue north into Alsancak along the shore, then turn east and connect to the D.300 and D.550 state highways in Halkapınar.

This part of the project was never built, due to public opposition, and the land originally reclaimed in Alsancak for the boulevard was converted into an esplanade.

Following the interchange, the boulevard turns west and runs directly along the coast with the Konak Tram and a wide pedestrian walkway on its north side.

The history of the Mustafa Kemal Coastal Boulevard dates back to 1973, when the Ministry of Public Works released the Metropolitan Area Masterplan (Turkish: Metropoliten Nazım İmar Planı).

[3] Two years later, the İzmir Municipality put forth plans to build a six-lane road from Üçkuyular (near İnciraltı) to central Konak, based on the 1973 masterplan.

Halil Rıfat Paşa Avenue was redesigned and the four-lane roadway continued into the tunnel, directly from the interchange with the coastal boulevard.

The extension was approved by the Ministry of Public Works on 15 November 1996, however the section between Konak and Cumhuriyet Squares was to be further studied and thus construction was delayed.

[2] In February 1997 the İzmir Board of Architects requested that the entire shore from Konak to Alsancak be declared a protected, historical area.

[2] On 17 April 1999 Ahmet Piriştina was elected mayor of İzmir and vowed to continue the construction of the boulevard in accordance with the law.
