re: #197 Decatur Deb

At some scale roads, railroads and river navigation all become organic—the need to replace dead tissues is part of the life process.

These projects are a bit above repair to same state. Most are widening from 4- to 6- lanes or conversion from state highway with at-grade crossings to limited access freeway and thus eligibility to be declared interstate highway. The I-99 work has also included new highway construction and bypasses since the old roads were not in good locations for widening.
