The northbound side of the bridge was widened ten years ago. To keep traffic flowing while the construction takes place, both north and southbound traffic will share the existing four lanes on the northbound side. Northbound traffic will be separated from southbound traffic by concrete barriers. On Sunday, contractors will begin building the lane shifts needed to channel southbound traffic over to the northbound side of the highway and back again at the end of the construction zone. The lane shifts will be constructed about a quarter mile before the bridge and a quarter mile after the bridge.
Contractors expect to complete the job by the weekend.
The traffic shift will remain in place until the Mousam River Bridge project is completed in late fall.
