Bago River Crossing
Project description
The new Bago River Crossing in the Yangon region of Myanmar has a total length of over 2.6 kilometers, including a cable-stayed bridge of length 448 m.
The new bridge was necessary to meet the increasing traffic demand between Yangon city and Thanlyin, and especially that of the Thilawa Special Economic Zone.
The structure also forms an important part of a series of the construction of the East-West Economic Corridor.
Upon its completion, it will reduce heavy traffic congestion and save time and fuel for commuters.
mageba scope
The bridge required the supply of four exceptional pendulum rocker bearings as well as almost 70 m of TENSA-MODULAR expansion joints with up to eight movement gaps each.
Pendulum rocker bearings can be designed to resist very large uplift (tension) forces, making them a good choice for this bridge in which the bearing tensile forces of 3,700 KN even exceed the compressive forces of 3,300 KN.
But the use of bearings of this type and size in bridge construction is rare, so each project to design and manufacture them presents challenges that demand skill and experience. The manufacturing tolerances were very low, and quality control and testing were closely monitored by the client. Careful planning, including an in-depth study of the installation sequence and trial assembly in the factory, was required to ensure proper and efficient installation on site.
