As of Sunday morning, contractor crews had replaced half of two of the huge expansion joints on I-90 at the East Channel Bridge and were putting down concrete over the new joints. Still to come is the removal of the other half of the old joints, installation of new joints, a 30-hour welding job and more concrete pouring.

The concrete needs about 12 hours to cure and reach a strength of 2,500 psi (pounds per square inch) in order to withstand for traffic.
