Data from new bridge to aid future designs
Published: December 09, 2003
Information gathered from a new “smart bridge” in New Jersey will be used to verify national design specifications. The US$30 million Doremus Avenue Bridge replacement includes technology to monitor conditions and provide data on the response to heavy loads and to the stresses due to seasonal temperatures. The bridge replaces a heavily loaded 1918 structure which was structurally deficient and had suffered differential settlement. The 401m bridge takes road traffic across 33 busy rail lines and has a superstructure of three three-span continuous welded plate girder units. It is the first of 11 schemes to be completed under the state’s Portway project to improve access between key places such as port and rail facilities. |
