SR-252 Wilson Pike Williamson County, Tennessee

SR-252 Wilson Pike

TRC Worldwide Engineering, Inc. was retained by the State of Tennessee, Department of Transportation to design the re-alignment and addition of two lanes to this existing State Route 252. TDOT considers this section of Wilson Pike in Williamson County as a priority for reconstruction because of substandard geometry and the need to improve safety.

Information relative to accidents, traffic and geometric deficiencies were evaluated. Existing traffic information was assembled to establish design criteria to meet current standard. Work elements that were included in the design of this project included: surveying, traffic design, highway design, geotechnical design, right-of-way design, utility design and permit preparation.

The final design included widening to provide two lanes in each direction making it a four lane highway. The improvements span a segment of approximately 2.5 miles.

The roadway cross-section width was increased to TDOT standards of 12 ft wide lanes with 8 ft wide shoulders including intersection improvements at each end.
