Basic information
Lin Lan Expressway is an important part of Lanzhou-Chongqing Expressway on National Highway 2 12, and it is the inter-provincial passage from Lanzhou to Mohan Port in western Gansu Province. It is also the south exit of Lanzhou and a shortcut to Lintao, the "back garden". The highway starts from Yanjiaping in Lanzhou, passes through Qilihe and Lintao counties, 8 towns and 55 administrative villages, and ends at Caojiagou in Lintao, with a total length of 92.69 kilometers.
On June 5438+February 18, 2004, Lanzhou-Lintao Expressway will be officially opened to traffic, which will further boost the high-speed process of 2 12 National Road going south along Lintao to Sichuan, optimize the road network structure in northwest China and promote the economic development in Longnan. At the same time, an "one-hour economic circle" centered on Lanzhou will also be formed.
This tunnel with a length of 4003. 19 meters (excluding ancillary parts) has not only become the longest highway tunnel in Gansu, but also won praise for its fast construction progress, good quality and no safety accidents during construction.
be open to traffic
After the Lin Lan Expressway was opened to traffic, all five exits in Lanzhou have been speeded up, and it takes only one hour to get from Lanzhou to Lintao. Lanzhou people who live in dry and dusty winter can buy Dahlia, gladiolus or purple peony brought from Lintao that morning.
The goal of building Lintao County into a satellite city and a back garden in Lanzhou is realistic because of the road. At present, the investment promotion project of the emerging 1,000-mu flower high-tech demonstration zone with a total investment of 65.438+0.29 billion yuan has been started. Its creative advertising words highlight the positioning of "the east bank of Taohe River, at 2 12 National Road 108 km". Lintao's real estate industry is also booming. Next to the expressway, there are rows of commercial houses. As the opening date of the expressway approaches, house prices are also rising.
The completion and opening of Lin Lan Expressway has further accelerated the process of 2 12 national highway entering Sichuan along the south of Lintao. It is reported that the preliminary work has been started for the national highway 2 12 high-speed project in Gansu. The Lintao-Guanzigou route at the junction of Gansu and Sichuan has a total length of 452 kilometers and an investment scale of about 28 billion yuan. It is known as the "Big Mac" in Gansu highway construction projects. The project will be implemented in three stages from the first 1 1 five-year plan.
