PR slogan for the four-lane expansion project Doto Expressway
To promote the four-lane expansion project Doto Expressway, we adopted the slogan "Eastern Hokkaido, One Heart."
This slogan embodies the firm determination of all those involved in the construction to work together as one to complete the four-lane expansion project, and the hope that the people of eastern Hokkaido will also support the project, as it will make Doto Expressway safer and more comfortable.
The logo was calligraphed by Suibi, a calligrapher from Obihiro, and features a design that incorporates the radical for "road" (道) into the "N" of NEXCO.
