Welcome to the captivating world of the Jinan Yan Shan Overpass, a marvel of urban engineering that connects the bustling city of Jinan with ease. This magnificent structure, often referred to as the "First Engineering Pride of the Province," deserves a closer look.

The燕山立交, a true masterpiece, stands as a five-level互通式 marvel, seamlessly integrating various traffic flows with its intricate design.

Constructed as a half cloverleaf and half定向型, the Yan Shan Overpass is not just a bridge, but a vital transportation hub for the southeastern and southern outskirts of济南. Spanning an impressive 401 acres, it reaches a towering height of 28 meters, featuring two mainline bridges and an impressive eight loop ramps, totalling a length of 7,812 meters. With a staggering investment of 2.74 billion yuan, this is no ordinary project, but a cornerstone of the 'Great Transformation of Jinan in Five Years' initiative by the provincial government.

Under the capable hands of China Railway Fourteenth Bureau Group's First Company, the 2A contract segment of the Yan Shan project took on the task of building a portion of this grandiose bridge. With a remarkable 3,127.7 meters of its length, the 413,690 square meters of bridge deck is adorned with 371 sturdy桩基, 159 massive concrete foundations, 190 elegant墩柱, and an impressive 47 consecutive spans of poured concrete, collectively representing half of the entire construction.

This engineering marvel not only showcases the city's commitment to efficient transportation but also stands as a testament to human ingenuity and the dedication of those who built it. The Yan Shan Overpass is not just a structure, but a gateway to a more connected and efficient Jinan, making it an essential part of the urban landscape.
