September 25, 2023 is a significant date for transport infrastructure in China. Today the tunnel on the Huanggang road near Jinan is officially open for the rukhu. This object is the first single-block double-decker tunnel in the region, laid under the Huanghe River behind the other tunnel complex.

Revolutionary breakthrough in everyday life.

The new tunnel will significantly shorten the travel time between key areas of Jinan. Previously, I walked by car from Longhu Park to Lanxiang Street, taking about 40 minutes. Now you can get up for only 5 rubles. This was made possible by an innovative two-tier design, which made it possible to accommodate six smugas (three per skin tier) in one tunnel block. The upper tier of assignments for the Rukh is from day to day, and the lower tier is from day to day..

Design with one block and two tiers is a significant advantage compared to traditional double-block tunnels. Thus, the decision is not only to save space, but also to substantially reduce investment costs for everyday life. The secret of being able to accommodate six smuhas in one block lies in the history of the giant tunnel complex " Its diameter should be 17.5 meters, which is 2-3 times larger than that of standard cars, which are used for everyday life in small subways..

Expansion of transport links and developments in the region.

Through the Huanggang Tunnel there is a greater number of crossings across the Yellow River between Jinan and 22. The tunnel directly connects with the Longhu interchange on the national highway G309. This will significantly improve transport accessibility and facilitate the integration of the main city district of Jinan with a new zone of transformation of kinetic energy. This, in its turn, gives strong support to the ecological protection and high-quality development of the Huanghe River basin.
