The Split required the removal of 60,800 sq yd of existing
asphalt and concrete pavements and 72,000 cu yd of excavation.
During the removal phase, an area of soft subgrade
was discovered in the southbound lanes between Fletcher
Avenue and Calvary Street bridges. Widening and lowering
the road called for the existing slopes to be re-cut to match
the new road grade. The slopes were much steeper than
anticipated, and the solution called for the use of rip-rap
to keep the slope in place.
