South Corridor Study Progress Update - September 15, 2021

Progress Update September 15, 2021

Impetus & Objectives

Regional Vision

• Regional Commuter Rail Study (1998) • Southeast Corridor Alternatives Analysis (2007) • Northwest Corridor Conceptual Feasibility Study (2010) • Downtown East‐West Connector Alternatives Analysis (2011) • I‐24 Corridor Study/ Monorail Assessment (2014) • Southeast Area Transportation and Land Use Study (2016) • Northwest Corridor Transit Study/ AA (2017) • High‐Capacity Transit Study (2017) • South Corridor Transit Study (CURRENT)

Study Area Stretching nearly 35 miles and connecting communities along the I‐65 and US 31 corridors between downtown Nashville through Maury County

Study Purpose • Advance recommendations from the publicly adopted Regional Transportation Plan and nMotion Transit Master Plan • Inform the regional Transportation Policy Board as it updates the regional plan and makes associated funding decisions • Identify potential capital and operational improvements for TDOT, local government, and transit agency implementation • Recommend a locally preferred alternative for introducing regional rapid transit along the corridor • Help inform site selection for economic development opportunities along the I‐65 and US 31 corridors • Identify opportunities to align local plans, design guidelines, and zoning ordinances to ready the landscape for a major investment

Key Outcomes A Community‐Driven Recommendation for Rapid Transit

Corridor‐level transit project with conceptual design, costs estimate, and advanced analysis on community and environmental impacts Guidance for funding, project phasing, and minimizing disruption • Optimization and augmentation of existing transit service • Guidance for local planning pertaining to land development and right‐of‐way preservation • Suggested considerations for pursuing changes to local or state policies and legislation • Useable information for continued education and outreach

Build Alternatives

Bus Rapid Transit 2 Alignment Options

Light Rail Transit 2 Alignment Options

Commuter Rail CSX & NERR Corridors

Bus Rapid Transit Interstate Alignment • 20.5 miles • 12 modified bridges • 2 bridges/stream crossings

Bus Rapid Transit Hybrid Alignment

• 21.5 miles • 21 modified bridges

• 1 highway‐rail grade crossing • 12 bridges/ stream crossings

Light Rail Transit Interstate Alignment • 23.4 miles • 1–2 tunnels • 7 modified bridges • 14 highway‐rail crossings • 50 bridges/ stream crossings

Light Rail Transit Hybrid Alignment

• 20.6 miles • 2 tunnels • 9 modified bridges • 17 highway‐rail crossings • 37 bridges/ stream crossings

Commuter Rail CSX & NERR Corridors • 47.5 miles in length • 10 modified highway bridges • 25 highway‐rail crossings • 29 bridges/ stream crossings

Baseline Assumptions 1. Implement programmed roadway and intersection improvements 2. Provide more frequent commuter bus service with potential for limited Bus on Shoulder service 3. Increase frequency and availability of local transit service 4. Upgrade technologies to bring the corridor on par with the I‐24 Smart Corridor 5. Increase the amount of mixed‐use and higher density development according to local plans and transit development potential
