This work will include removing damaged portions of concrete, grinding the deck smooth with a specialized piece of equipment called a skidabrader, and repouring a new concrete deck. Northbound I-5 will continue to be reduced to two lanes around the clock until work on the left side of the bridge deck is completed, now scheduled to be May 25. Earlier in the week, crews were ahead of schedule and predicting they may be able to open the bridge to four lanes of traffic a few days early. Delaminated concrete is concrete that did not bond properly to the bridge deck. Delamination is a common occurrence and can happen for a variety of reasons.
Weather continues to be a critical factor in completing the project on time.
Weather permitting, the current schedule is to shotblast the left side of the bridge deck Thursday, and begin the 20-hour process of pouring concrete on Friday. Since crews are now working on the left side of the deck, these ramp closures are no longer necessary and both ramps are scheduled to remain open through the remainder of the project. The I-5 Express Lanes will continue to operate northbound for longer hours each weekday and over weekends to help alleviate northbound congestion resulting from the lane closures. They will open southbound each weekday from 5 a.m. to 9 a.m. Over the weekend of May 18, the Express Lanes will remain open northbound around the clock.
