Construction of this section is proceeding. The redesign for this section has required the removal of the natural soil (generally red clay) down to a depth of ~8' below the road surface level and the building of substantial bulkheading (subsurface sidewalls) to accomodate the aggregate materials which will underlay the asphalt surface. The final surface will be raised to ~the same height as the original road shoulder. These aggregates are being applied in 6" layers with compacting done for each layer. As of September 25th several additional aggregate layers are still to be put in place before final surface grading and smoothing can be done. With these steps still to be done, it appears that the asphalt surface will not be laid before the week of October 7-11.
The initial portion of the ATT bridge over I-40 was installed overnight on April 27-28. I-40 was closed and detoured for about 8 hours and the installation went as planned. See picture of the span above.
