The closure is expected to remain in effect for about a week.
Traffic will be detoured to US 84 Business and routed around the overpass before being directed back to westbound I-20.
The 3/4-mile detour is the same route that was used immediately following the collision. Signs, cones and message boards will be in place to direct drivers.
Both westbound lanes of I-20 will reopen after this phase of the work is complete, but future closures will be necessary as work progresses to replace the bridge.
