Today, road construction which works as a natural consequence of extending the transport network and concordantly making tunnels and viaducts have brought change and differences in general appearance of the landscape. Roads, bridges, viaducts and tunnels, as elements of the transport network are straight corridors that solve the flow of traffic. They also play an effective role in creating beautiful landscape. So simultaneously they have various functions in city structure. The design of highway tunnel portals includes the structure entrances design, hillside stabilisation, greenery systems, and landscape design effects. This paper reveals the importance of the tunnel portals in terms of landscape design and how they must be addressed with respect to design principles. Moreover, the architectural and landscape aspects of design applied to tunnel portals was analysed and compared with alternative architectural solutions.
