The longitudinal construction joints on this segment of roadway, Interstate 494 from Mile Post 2.143 to Mile Post 7.461 in both directions a three to four lane divided urban freeway, had deteriorated to the point that they were a possible safety issue, especially for motorcyclist. The Metro District maintenance forces had tried different methods of patching the longitudinal joint failure. The methods tried are either very expensive or leave poor driving surface. The decision was made to try using the Micro Surfacing technology to see if this would fill the joints and leave a smooth durable driving surface. The intent of the project was to repair the right fog line and the two skip lines that where exhibiting failures.
