The Steel-Box Girder Section Of The Overpass Which Crosses Xinyi Street On Kaiyuan Highway Was Completed For Closure
The steel-box girder section of the overpass which crosses Xinyi street on Kaiyuan highway was completed for closure after hoisting of the last steel-box girder at 4am on 26th December by Henan Province Installation Group ltd.
The steel-box girder,which is made up of three spans, is around 120 meters long, 22.4 meters wide and 1800 tons in total. The part that crosses Xinyi Street is 45 meters long with bi-directional four lanes. In order to reduce the effect to nearby community, market and public traffic, the project team discussed several round and come up with the optimized solution that the steel box-girder be made and pre-assembled for each section in workshop, do the whole assembling on-site, and start hoisting at mid-night and resume traffic in the morning. Regardless of the cold weather, our workers complete the installation in 5 nights which is 4 days earlier than the plan. The following units offered us great support to ensure the installation in safe and order:
Luoyang Housing and Urban-Rural Development Bureau
Henan Tianxing Project Construction Supervision Co., Ltd
Henan Guoan Construction Group
Luolong District Traffic Police
Next we will continue to speed up the progress of welding to save time for the following procedures like deck pavement and other ancillary works.
It is known that the project that crosses Xinyi Street on Kaiyuan Highway starts from Chang Xiamen Street to Kaiyuan Bridge and is 1.05 kilometers long with red-line width of 65-123 meters and it will works as urban arterials. The project sets On & Off ramp at east side of Xinyi Street and Semi-Cloverleaf interchange at west side of Letian Road. And its completion will release the traffic stress by increasing traffic efficiency of Kaiyuan highway and Xinyi Street and will also play an constructive role for the development of Luolong district and Yibin District.
