TIP Description: y
The North Carolina Department of Transportation proposes to construct interchanges on US 421, south
of Greensboro, replacing the temporary at-grade intersections of Woody Mill Road (SR 3389) and
Neelley Road (SR 3418). All existing, temporary at-grade intersections along US 421 within the project
limits will be permanently closed. Minden Road (SR 3413) will be extended parallel with US 421 and
will intersect Company Mill Road (SR 3394), south of the proposed Woody Mill Road Interchange.
1. Meeting Purpose
Presentation of relevant information concerning the recommended widening altematives, studied in the
Environmental Assessment, for inclusion in Merger 01 Process at the 4B Stage. An Environmental
Assessment for this project was approved on October 30, 1998 and distributed.
2. Project Status
• Purpose & Need:
Pureose: Safety enhancement of US 421 by eliminating at-grade
intersections between the I-85 Bypass Interchange and the existing
NC 62 Interchange, south of Greensboro.
Need: US 421 was relocated and constructed as a four-lane, divided
highway with full control of access in 1972. Interchange locations
were designated; however, the proposed interchanges at Woody ~z~^
Mill Road and Neelley Road were built as temporary at-grade ~ ry~v1 L ,
intersections due to funding constraints. Right-of-Way wasp ~~ ,.,;~`
acquired for future interchange construction.

^ Alignment Alternative A-2 (Diamond Interchange) and Service
Road A are currently recommended for construction at Woody
Mill Road.
^ Alignment alternatives B-3 (Half-Clover Interchange) is currently
recommended for construction at Neelley Road.

Based upon the current functional design plans for the Neelley Road

~, and wetlands south of this interchange will be impacted.
Based upon the current functional design plans for the Woody Mill Road
Interchange, there will be two crossings of an unnamed tributary to Big
Alamance Creek, downstream of the existing crossing. The existing
upstream structure is a 60-inch CMP. In order to reduce the number of
stream crossings and to mitigate for riparian buffer impacts to the
stream, it is recommended that the stream be relocated north of the

proposed westbound exit ramp in the northeast quadrant. This will
result in crossing the stream once with a 60-inch RCP: The length of
the proposed stream relocation would be approximately 820 feet. This
action would provide an opportunity for stream enhancement since the
new stream would be designed and built with the requisite replacement
of riparian buffers.
Both interchanges are in a water supply watershed with a best usage
classification of WS-IV NSW. The project is not in a designated high
quality watershed or within half a mile of the critical water supply area.
No hazardous spill containment measures will be needed. Standard
levels of erosion control will be applicable. The project will follow
NCDOT Best Management Practices for Protection of Surface Waters.
