See Photo 4 dated 06/26/2018. <br />The bottom 12 inches of the abutments and Piers 2 and 3 have light scaling for the full width of the culvert. In a few places, this <br />condition has progressed to large, shallow spalls, exposing the large aggregate. The aggregate appears sound. See Photos 2 and 6 <br />dated 06/26/2018. There is an outstanding work recommendation to clean the sediment out of the spans and test the soil for corrosive <br />conditions. <br />There is heavy efflorescence build up in the bottom half of Abutment 5 between the abutment face and the right wingwall. See Photo <br />5 dated 06/26/2018. <br />There is a 0.13 inch wide full height vertical crack with edge spalling in the left side of Abutment 5. Extending from this crack are full <br />width 0.02 inch wide discontinuous horizontal cracks spaced at 4 feet apart into Abutment 5. See Photo 1 dated 06/26/2018. <br />The abutments and Pier Walls 2, 3 and 4 have full height vertical cracks up to 0.02 inch wide and spaced as close as 4 feet on <br />center. <br />There is a 6 foot wide x 12 foot long x 2 foot deep scour hole along Abutment 1. See Photo 2. <br />The downstream invert is exposed up to 1.3 feet vertically for a length of 10 feet with no observed undermining at Pier 3. See Photo 4 <br />dated 06/14/2020.
