Thursday night’s collapse of the I-5 Skagit River Bridge horrified this ex-Secretary of Transportation, as we at WSDOT have always taken great care to maintain the safety of travelers on our structures. While this steel truss bridge is similar to the type of bridges carefully scrutinized nationwide after the I-35 bridge failure in Minnesota in 2007, this was not one of the bridges on our watch list.
In spite of its nearly 60 years in service, it was in reasonable structural condition. With early reports that a truck carrying an oversized load might have struck the bridge and caused the collapse, and the recovery of passengers safely complete, our attention turns to what will happen next.
The good news is there is no other team of public servants as accomplished in emergency management as the Washington State Department Of Transportation and State Patrol. These dedicated employees have had plenty of experience with transportation crises in recent years. As the Skagit River bridge site is secured and damage assessed, WSDOT engineers, traffic managers, budgeters and communicators are already at work on a plan to restore traffic to this critical West Coast economic corridor.
The first order of business is to establish a detour for the over 70,000 vehicles that use I-5 in this area daily. This will require close coordination with the city and county on appropriate local roads that can accommodate a long-term diversion of freeway traffic. Up-to-date road signage, variable message signs and coordination with businesses affected in the corridor are all necessary to help manage the traffic diversion through the duration of the closure. The length of I-5 from the Canadian border through the state will carry electronic messages about the traffic detours available. The most important thing the department will focus on is communication far and wide so that people and businesses know what to expect.

Given that the bridge is too narrow for today’s needs, it would be dangerously irresponsible to replicate it. We need a bridge wide enough to meet today’s standards. Is it even legal to build such a narrow bridge today?
It would be OUTRAGEOUS to duplicate an error by not replacing the existing portion of the bridge as well as the destroyed bridge.
