??As important traffic infrastructure, the “five vertical and seven horizontal” of national
trunk highways have faced with many challenges, such as how to deal with ecological civilization
development demand, how to respond to the international development trend of perfect fusion for
road engineering technology with aesthetic, philosophy, sociology, landscape and recreation, etc.
and finally achieve successful transformation and upgrade in the new period. It has been a hot spot
and has shown an unprecedented necessity and urgency at the present. How to upgrade trunk road
and what the landscape of trunk road should be after the upgrading and reconstruction are all major
issues which should be studied seriously. Historic River Columbia Highway is an excellent example
of being reborn through successfully restoring, constructing and upgrading, which offer a new trend
of construction and upgrading for that of arteries in China. Firstly, this paper summarizes the realistic
demand of constructing and upgrading of the arteries in China. Furthermore, the case of Historic
River Columbia Highway is introduced and profoundly explained, through the general situation
and history, combined with the project of restore and construction. Finally, the enlightenment
about restoration of Historic River Columbia Highway for upgrading and construction of Arteries
in China is raised.sformation of bicycle all over the world, how about our country’s situation of
bicycle? Where is the gap between us and the present bicycle-rich countries? Where is the way of
the development of bicycle? This article presents the development history and research progress of
bicycle overseas, as well as analyzes the research situation and predicament of bicycle traffic in our
country. The paper then concludes with some useful insights for the development of the bicycle
use in urban China.
