Outline of opening section

(1) Outline of open section
Do-O Expressway has been opened sequentially between the Ochibe IC and Yakumo IC in 2009 and the Mori IC and Ochibe IC in 2011.
The section to be opened this time has been acquired since 2001, construction work has been started in sequence, and it will be opened this time.

(2) Ingenuity in the field
(2)-1 Initiatives for safety and security
As a measure to prevent lane departure due to sideways driving or drowsy driving, we have installed an alert ditch (rumble strips).

In addition, we are introducing a wire rope type protective fence that can be expected to improve service levels and reduce serious accidents in face-to-face sections in some sections (about 1.6 km).

(2)-2 Environmentally friendly efforts
Aiming to create an environmentally friendly road, we focus on scallop shells, which are disposed of as wastes of about 200,000 tons per year, and use an asphalt paving mixture that utilizes this powder. This contributes to the formation of a recycling-based society. In addition, as a measure to prevent invasion of animals, a fence with a height of 2.5 m is installed against the invasion of large animals such as deer, and a wire mesh is used to block the bottom of the fence to prevent invasion of small animals such as foxes. I will.

As an effort to reduce power consumption, we have adopted LED-type lighting with low power consumption such as self-luminous snow poles in addition to lighting fixtures and road signs that have been introduced in the past.

Maintenance effect

～ Further improvement of convenience in the central and southern areas of Hokkaido and strengthening of redundancy function in case of disaster ～
With the extension of Do-O Expressway opening, the convenience of the central and southern Hokkaido areas is improved, punctuality and safety are ensured, and the total travel time from Sapporo to Hakodate is approximately 80 minutes compared to using general roads. It will be shortened, and it is expected that Large in the tourism area and regional revitalization and exchange will be promoted.

In addition, general national road No. 5 has been closed due to heavy rain and the tsunami during the Great East Japan Earthquake, resulting in a large detour. With the establishment of the Expressway network including the opening of this time, redundancy in the event of a disaster is secured, and it is expected that the functions of logistics and emergency transportation routes will be enhanced by improving punctuality and safety.

-Improved speed of emergency transportation in Southern Hokkaido-
By extending the opening of the Do-O Expressway time required for emergency transportation to the municipal Hakodate Hospital, which has a higher-order emergency medical institution in Hakodate, is shortened and the burden on patients is reduced, contributing to rapid, safe and secure emergency transportation. I will.

～Smooth movement to tourist spots～
Due to the extension of the Do-O Expressway travel time has been greatly shortened, travel to tourist destinations has become smoother, and rich forests and a wide variety of flora and fauna have been recognized, including Onuma, which was registered under the Ramsar Convention on July 3, this year. Access to Onuma Quasi-National Park is improved.
