There are two separate phases to this work. Phase 2 Concrete Pouring - Upcoming Crews will complete the concrete pours one area at a time. Each area will take approximately 2 weeks to complete the concrete pouring. A work zone will be set up around the concrete trucks as they pour, and it will be taken down nightly. Concrete pour work will occur between 7:00AM and 11:00PM. During the pouring phase, there will be an increase truck flow to deliver the concrete to the site. Once the concrete pouring is complete the roadway holes will be filled and restored. 8
