On-Call: Slater Road Bridge Collision Damage
Repair Design, Whatcom County
Slater Road Bridge is a 240-foot, 32-foot wide, fracture critical, thru-truss steel bridge. In August 2006, this was struck by a truck and experienced major damage. The collision damage included partial tear of east of portal, shearing off of two sway frames, bending of two major vertical members of north thru-truss by as much as 18 inches, and other less major damages gathered around the bridge. The County closed this important roadway and asked TranTech to be involved with this project, in an emergency manner. TranTech staff in a condensed and quick response manner prepared repair drawings and technical specifications for these repairs in a period of less than three weeks.
The repair included heat straightening of many members and accurate replacement of heavily damaged members. A 3-D model of the bridge was used for various retrofit investigations. TranTech also provided construction inspection and support for this project during the construction phase. The construction phase was completed in two weeks and the bridge was open to traffic in early October 2006. Moreover, TranTech provided as-built drawings and post repairs, loading rating for the bridge. Whatcom County was very pleased with the speed and quality of services provided by TranTech on this project.
