Nashville Public Works: Roads, Infrastructure, and Maintenance Responsibilities

Nashville's Department of Public Works manages a road network, stormwater system, and maintenance operation that directly affects the daily mobility and safety of Davidson County's roughly 700,000 residents. This page covers the definition and functional scope of Metro Nashville Public Works, how the department executes its responsibilities, the scenarios residents most frequently encounter, and the critical decision boundaries that determine which entity — Metro, the state, or a private party — is responsible for a given asset or complaint.

Definition and scope

The Nashville Public Works department operates under the Metropolitan Government of Nashville and Davidson County, the consolidated city-county government established by charter in 1963. Its mandate covers the construction, repair, and maintenance of public infrastructure within Davidson County's jurisdictional boundaries, including approximately 5,800 lane miles of roadway, stormwater drainage infrastructure, traffic signals, street lighting, and solid waste collection.

Public Works is a department of Metro government, meaning its budget is approved annually through the Metro Council and the Mayor's Office. Funding flows through the general fund and dedicated stormwater utility revenues. The department operates distinct divisions, including Road Operations, Stormwater, Traffic and Parking, and Fleet Management.

Scope and coverage limitations: This page addresses the responsibilities of Metro Nashville's Public Works department within Davidson County only. State-maintained roads — including Interstate highways, U.S. routes, and Tennessee state routes passing through Nashville — fall under the jurisdiction of the Tennessee Department of Transportation (TDOT), not Metro Public Works. Residents in municipalities adjacent to Nashville, such as Brentwood (Williamson County) or Hendersonville (Sumner County), are governed by their respective county or municipal public works departments. Infrastructure within private subdivisions or gated communities generally does not fall under Metro Public Works maintenance obligations. Metro's authority does not extend beyond Davidson County lines.

How it works

Metro Public Works executes its responsibilities through a structured operational framework organized around four core functions:

1. Road maintenance and repair — Crews address pothole patching, resurfacing, crack sealing, curb repair, and signage replacement on Metro-maintained streets. Annual resurfacing programs prioritize roads based on Pavement Condition Index (PCI) scores, a standardized 0–100 scale used nationally.
2. Stormwater management — The Stormwater division maintains drainage infrastructure including culverts, detention basins, and storm sewer lines. It also enforces Nashville's Municipal Separate Storm Sewer System (MS4) permit, issued by the Tennessee Department of Environment and Conservation under the federal Clean Water Act.
3. Traffic operations — The Traffic and Parking division manages approximately 800 signalized intersections in Nashville, maintains pavement markings, and coordinates construction zone traffic control plans.
4. Solid waste and recycling — Residential curbside collection, bulk item pickup, and household hazardous waste disposal programs are administered through Public Works, with collection routes covering the residential areas of Davidson County served by Metro.

Requests for service — pothole repair, debris removal, drainage complaints — are routed through the Metro Nashville 311 system, which logs, assigns, and tracks each request. The department also coordinates with Nashville Metro Planning Commission on capital improvement projects that involve road realignment or new infrastructure tied to development approvals.

Funding for major infrastructure projects is appropriated through the Metro budget process, and large capital projects may involve federal funding administered through TDOT or the Federal Highway Administration (FHWA).

Common scenarios

Residents interact with Metro Public Works in predictable situations:

• Pothole on a neighborhood street — If the street is Metro-maintained (not a state route), a 311 service request triggers a work order for the Road Operations division. Response times vary by severity classification.
• Flooded yard or standing water after rain — If the flooding originates from a Metro-maintained storm drain or culvert, the Stormwater division investigates. If the drainage issue is on private property or within a private subdivision, Metro typically does not intervene.
• Damaged traffic signal or missing street sign — Reported through 311 and routed to Traffic and Parking. Signal outages are treated as priority responses given public safety implications.
• Tree limb or debris in the roadway — Metro Public Works handles debris on public streets. Trees on private property that overhang or fall into public right-of-way follow a shared-responsibility protocol depending on ownership.
• Construction damaging a public road — Contractors performing utility or development work in the public right-of-way must obtain a Right-of-Way permit from Metro Public Works. Damage to pavement caused by permitted work is the contractor's responsibility to restore to Metro specifications.

Decision boundaries

Understanding which entity holds maintenance responsibility prevents misdirected complaints and delays. The key distinctions follow a clear hierarchy:

Metro Public Works vs. TDOT:
State routes (identifiable by their Tennessee route shield signage) running through Nashville — such as SR-155 (Briley Parkway) or portions of SR-24 (Murfreesboro Road) — are maintained by TDOT, not Metro. Crash damage, pothole repair, and signal maintenance on those corridors are TDOT responsibilities. Residents should contact TDOT's Region 3 office for complaints on state-maintained roads.

Metro Public Works vs. private responsibility:
Infrastructure inside recorded private subdivisions — internal roads, private drainage easements, shared driveways — is the responsibility of a homeowners association or the property owner, not Metro. Metro does not typically accept dedication of substandard roads; roads must meet Metro specifications before Public Works assumes maintenance liability.

Metro Public Works vs. Nashville Water Services:
Water and sewer infrastructure falls under Nashville Water Services, a separate Metro department. A sinkhole caused by a broken water main is a Water Services matter, not a Public Works matter, even if it appears on a public street surface.

Metro Public Works vs. Nashville MTA/WeGo:
Bus shelters, transit infrastructure, and paratransit operations fall under Nashville's transit authority. Public Works may coordinate on road access and right-of-way, but transit asset maintenance is a distinct function.
