PURPOSE OF THIS MEETING The purpose of this meeting Is to update the merger tearn on the project status and introduce the revised alternative to be carried forward for detail study. 2. INTRODUCTION The North Carolina Department ot Transportation (NCDOT), in cooperation with the Federal Highway Administration (FHWA), proposes a bridge replacement and an improvement to the existing interchange on US 29 at SR 4771(Reedy Fork Parlcway) in Guilford County. The proposed project would also inciude the realignment, part on new location, and upgrade of the existing SR 4771 {Reedy Fork Parkway} and SR 2526 (Summit Avenue}. The proposed action Is included in the 2p16-2025 StateTransportation Improvement Plan (STIP) as project number R-4707. 2.1: PROJECT IIVFORMATION The project is located in northern Guilford Caunty, approximately eight miles northeast of downtown Greensboro (Figure 1). U5 29 is a four-lane, rnedian-divided facility that linlcs I-40 in Greensboro with US 58 in Danville Virginia. The study area is moderately developed and includes a mixture of light industry, institutional, and residential uses. There are currently plans for additional commercial, industrial and resi@ential development in the vfcinity of the existing interchange. Trafflc volumes are projected to increase on Reedy Fork Parkway Interchange from an average of 40,000 vehicies per day (vpd) in 2015 to 72,000 vpd in 2035. 7he existing US 29 Interchange, Sumrnit Avenue, and Reedy Fork Parkway are not capable of handling these traffic volumes without experiencing substantial delays and increased accident potential. 2.2. PUBLIC lNVOLVEMENT A Citizens Informational Workshop (CIW) was held on November 13, 2006 at the Reedy fark Community Center. Participants were able to view the alternative exhibits that depicted environmental constraints, proposed study area, business access and typical sec#ions. Some concerns raised by the public regarding the project included truck access to local businesses, existing delays at study areas intersections, and increased truck traffic within the study area. Employees from local businesses directly impacted by the proposed project expressed the need for a traffic Iight at the intersection of Eckersan Road and Reedy Fork Parkway. Concerns were also raised concerning the existing roadway design not supporting wide #urns for large trucks and the need for future designs to support the large truck volume that is anticipated to serve the local industrlal facilities in the study �rea. Citizens also praised the inclusion of future bicycle facilities included in the project design. Due ta the passage of time and re-initiatEon of the praject development process, a Public Meeting was held on April 21, 2016 to update the public on the project studles, to present the design alternatives, and to request their comments on the design alternatives and the project in general. Cancerns were raised similarto the one raised in the 2006 Public Meeting. Merger Concurrence Poinf 2 Revisifed S7lP Project R-4707 ' Page 1 May 18, 2016 3. MERGER TEAM CONCURRENCE TO DATE 3.1 CP1 & CP2: PROJECT PURPOSE AND NEED AND STUDY AREA DEFINED AND DESIGN OPTIONS FOR DETAILED STUDY The Merger Team concurred on the following Purpose and Need Statement and Study Area on September 21, 2006. � The Study Area extencls approxfmately 5,000 feet north of the existing interchange along tJS 29 and approximately 3,000 feet south along iJS 29, SR 2641(Bryan Park Road) and 5R 25Z5 (Summit Avenue). The Study Area also extends approxfmately 3,000 feet south east along SR 4771(Reedy Fork Parkway) • 1'he project's purpose is to provide a set of objectives that will address the transportation needs identified in the study area. The purpose of the proposed project is to replace the�structurally deficient bridge over US 29, improve the interchange to meet interstate standards and accommodate future traffic volumes from the Reedy Fork Ranch Mixed Use Development. The Merger Team also concurred on the Design Options for Detailed Study on September 21, 2006 for the following alternatives: • No-Build Alternative: Make no improvements • Alternative 1(SPUI1: This is a single point urban interchange where all left turns are handled at one signalized intersection and all right movements are free flow. • Alternative 2(Partial Cloverleafl: All ramp movements are located on the south side of the interchange.. • A(ternative 3(Traditional Diamond}; This design has a one-way diagonal ramp in each interchange quadrant with future loops at two quadrants. The ramps are aligned with free-flow terminals on US 29 with signalized intersections on Reedy Fork Parkway at the ramp intersections. 4. CP2: ALTERNATIVES CONSIDERED 4.1 SUMMARY OF ALTERNATIVES TO BE CONSIDERED 7he identification, consideration, and analysis of alternatives are key to the NEPA process and the goal of objective decision-making. Consideration of alternatives leads to a'solution that satisfies the transportation need and avoids and minirnizes adverse impacts to environmental and cornmunity resources. In addition to the Na Bufld Alternative, build alternatives listed in the next section were studied. With the funding constraints, this project was on hold for few years. In 2013, the project was reinitiated to refine and update the design aiternatives with updated traffic voiumes. At the request of the City of Greensboro and the Greensboro Urban Area Metropolitan Planning Organization (GUAMPO}, a Diverging Diamond Interchange (DDIj Alternative was added. Merger Concurrence Point 2 Revisifed STIP Project R-4747 Page 2 May 18, 2096 4.1.1 Bufid Afternatives 7he 8uild Alternatives under consideration for R-4707 consist of four interchange configurations. Each interchange configuration wfll meet the project's purpose and need by providing a new bridge and improved interchange. All build alternatives wfll meet the purpose and need of the project. The connecting roadways associated with the tonstruction of the new Reedy Fork Parkway Interchange on US 29 would not vary between the Build Alternatives: In all Build Alternatives, Reedy Forlc Parkway connects to US 29 with the following improvements: • Removal of the exlsting structurally cteflcient bridge over US 29; • improvements to the existing SummitAvenue; • Improved traffic flow, safety, and truck movements; • Improved bicycle and pedestrian facilities on Reedy Fork Parkway. Bulld A{ternetive 1: Single Potnt Ur.ban Interchange (SPUIj - The SPU1 AlternatiVe involves the signalization of three intersections on Reedy Fark Parkway between Summit Avenue and Eckerson Road (see Figure 2). Summit Avenue will be realigned to tie into the realigned and extended Reedy Fork Parkway forrning a signalized four-leg intersection. Build Alternative 1 Revised: Diverging Diamond Interchange (ODI) — A Diverging Dfamond Interchange �DDI) is a type of diamond interchange in which the two directions of traffic from US 29 cross to the opposite side on both sldes of the bridge at the interchange {see Figure 3). The DDI Alternative involves the signalixation ofthree intersections on Reedy Fork Parkway between Summit Avenue and Eckerson Road. The DDI has a smaller bridge cornpared to the SPUI and fits within the footprint established for the SPUT Alternative. Bulld Alternative 2: Partial Cloverleaf Interchange — The partial cloverleaf interchange includes a loop and a ramp in the southeast and southwest quadrants of the proposed Reedy Fork Road Interchange (see Figure 4). The ramp terminals connect with planned roadways on the north side of Reedy Fork Parkway. Buifd Alternative 3: Traditional Diamond - The Traditional Diamond Alternative design has a one- way diagonal ramp in each interchange quadrant and two future loops at two quadrants (see Figure 5). The ramps are aligned with free-flow terminals on US 29 with signalized intersections on iteedy Fork Parkway at the ramp intersections. 4.2 ANALYSIS OF BUILD ALTERNATIVES The project Roadway Engineers have established anticipated right-of-way requirernents based on preliminary functionat roadway design. Due to �ariations in the topography, among ather factors, there are some variations along each alternative. 7he anticipated right-of-way limits were utilized to develop anticipated impacts foreach Build Alternative. Merger Concurrence Point 2 F2evisited STIP Project R-4707 Page 3 May 98, 2016 Stream impacts were caiculated in GIS to include the portions of ffeld-delineated streams beyond the existing right-of-way limits (where applicable) and wtthin the anticipated right-of-way requirements. Table 1 summarixes the impact analysis. All impacts included in this report are based on preliminary functionaE roadway design; avofdance and minimization will continue to be pursued throughout the clesign development.

INTERIM DESIGN The existing Reedy Fork Parkway Bridge (Bridge IVo. 360 in Guilford County} carries SR4771 over US 29. The bridge was constructed in 1961. The 2014 bridge inspection report indicates a condition rat}ng of "Poor' for the Deck, Superstructure, and Substructure. The estimated remaining fife per the bridge inspectian report completed in 2014 report is 2 years. Due to the extensive deterioration of essential superstructure and substructure components and the associated condition ratings, this bridge is cansidered "Structurally Merger Concurrence Point 2 Revlsited STlP Pro%ect R-4707 - Page 4 May 98, 2016 Deficient" according to FHWA guidelines. The FHWA Structural �valuatfon of the bridge is 2, indicating that the structural condition of the bridge is basicaliy intolerable, requiring hlgh priority of replacement (per the FHWA Coding Guide). Based on the condition of the existing bridge, an Interim Design (Figure 6) is developed to replace the bridge priorto the construction of the full interchange. The Interim Design is located within the footprint of the build alternatives. The phased construction is programmed to start in 2419. 6.
