At the same time, limited by field conditions, some weighing more than 100 tons of slab to be raised to 60 meters high from the ground to set up the bridge. Shop particular kilns - Ling section of the river, widening existing roads on the transformation of the construction work is more narrow face, many places can only guarantee
The width of the basic machinery operation permit.
Xu said, Fujian, Guang Shan high-speed builders made a "military order" at all costs, the 2010 Chinese New Year before the reopened section of 1.5 km off the board. Moreover, the wide side of Shaanxi to build high-speed construction, while the second expressway to ensure that line operators Guangmian normal road traffic safety, to the construction side of the great difficulty of building management and security through pressure.
25 months of "eating" the longest tunnel under

Introduce Fujian Xu, Guang Shan Mountain in the ancient highway tunnel length of 2100 meters, multi-hole the lava is very complicated geological conditions, leading to driving speed is very slow, start from April 2008 since the construction of the tunnel builders to overcome difficulties.
"Guang Shan Freeway tunnels total length of 7 km, 27 km bridge." Xu said, Fujian, June 13, 2010, wide off the board of Shaanxi Highway Tunnel, tunnel slope Qinglin, Jiashan ancient tunnels, moon Gap tunnel, fly Cui Jia Ya Sin tunnel off the tunnel and finally all six through the tunnel. Construction, the rugged terrain of the road as far as possible through the use of bridge and tunnel options, less filling little digging, try to protect natural vegetation and along the mountain slope, reducing soil erosion.

Smooth traffic
Connect Northwest North Second Line contingency channel
Shaanxi High-speed wide four-lane two-way full range of standard construction, the design speed of 80 km per hour. Asphalt concrete pavement.
In the neutron, air, building trenches, Shahe, kilns and other shops and six on the West Dam set the interchange, Ling Jiang Extension Interchange, located a main toll stations, ramp toll station 6. The road connecting the Northwest of Sichuan, an important hub in North China and Sichuan and out of the important channels.

"In recent years, cotton wide high-speed traffic pressure particularly the second line." Guangyuan City Public Security Bureau deputy director overturned District Public Security Bureau, said Yuan Ming, in particular, "5.12" earthquake, the second line Guangbei traffic surge average daily traffic volume soared to more than 40000 vehicles, is designed to pass 10 times the amount, once the traffic is congested.
