The final 12-hour detour at the Skagit River Bridge on Interstate 5 is expected starting Thursday, Nov. 7.
That day, both directions of the freeway will detour through Burlington from 8 p.m. until 8 a.m. while contractor crews continue to retrofit the steel overhead trusses.
Plans also call for early morning delays Friday, which will likely occur between 5:30 and 8 a.m., lasting 20 minutes or more by 7 a.m. and until the bridge reopens to traffic.
The bulk of the bridge retrofit work has required nighttime eight-hour detours and single-lane closures. Fortunately, the crews will have completed that part of the work using only five of the seven planned 12-hour detours.
Drivers will follow the same detour routes established when the bridge was closed last May. A section of the bridge collapsed into the Skagit River after the bridge was struck by a tall truck.
More lane closures and eight-hour detours are scheduled at the bridge next week.
