Transportation Construction Expert Witnesses & I-5 Bridge Collapse

Transportation construction expert witnesses may provide reports and testimony regarding design, surveying, construction, operation, and maintenance of highways, roadways, bridges, and tunnels, as well as associated matters. In the news, a bridge on I-5 near Mount Vernon, WA, collapsed after a semi-trailer truck hauling over-sized drilling equipment struck the bridge's trusses. The 55 year old bridge is rated a "fracture critical" design - the failure of just one part could cause the entire bridge to collapse. According to the US DOT website:

The bridge carries an estimated 71,000 vehicles each day and is a major commercial route between Washington and Canada. Approximately 11 percent of the vehicles are commercial trucks transporting goods between the two countries.
