WJE Provides Specialty Bridge Engineering Services for Route 291 Truss Bridge

November 1, 2009
Wiss, Janney, Elstner Associates, Inc. (WJE), completed a three-month evaluation of the Route 291 truss bridge over the Missouri River. The Missouri Department of Transportation (MoDOT) retained WJE in early July to provide specialty engineering services to address concerns about the structural integrity of the sixty-year-old northbound structure located outside Kansas City. Gusset plate corrosion had reached a point where MoDOT inspectors and bridge engineers felt remedial work might be necessary. Over the three-month period, WJE structural engineers analyzed the structure to determine its capacity, performed detailed evaluations of the deteriorated gusset plates, developed repair details that addressed the full range of existing conditions and could be installed quickly and without shoring, and completed eighty-four gusset plate and member repairs to restore live load capacity to the desired level. WJE completed work on the project in early October.

"The Route 291 Bridge project was an excellent opportunity to demonstrate cost-effective repair options for deteriorated gusset plates in truss bridges," said WJE Project Manager Jonathan McGormley
