Bus Line Refresh (BLR) is Pittsburgh Regional Transit’s strategic update to the bus network—designed to reflect how people travel today while building on the routes riders rely on every day. Shaped by more than 16,000 comments from riders, operators, and community members over multiple phases of engagement, BLR reflects what we heard clearly and consistently:
BLR is not a wholesale redesign of the system. It’s a focused, network-level refresh that strengthens what works, improves reliability and frequency, and reallocates our limited resources where they will have the greatest impact.
The bus network we have today was built around travel patterns from decades ago when peak-hour commuting to Downtown drove service design. Today, travel looks different.
Since the pandemic, ridership has returned strongest during the midday, evenings, and on weekends. At the same time, some routes operate with very low ridership while other corridors experience overcrowding or reliability challenges. Meanwhile, transit demand exceeds the available funding and staffing.
BLR realigns service with current demand. Downtown remains the region’s primary transit hub, but service is adjusted to better support everyday trips such as shift work, healthcare visits, education, errands, and weekend travel. This refresh reflects how people actually use the system today - not how it was used in the past.
Transit needs in our region exceed the funding and operational resources currently available. The Proposed Final Network is PRT's answer to that gap — not a reduction in service, but a smarter redeployment of it. The plan is fiscally constrained to today's operating budget and doesn't assume funding PRT doesn't have.
The segments proposed for discontinuation carry extremely low ridership, serving less than 1% of current riders. Every hour saved is reinvested in the network — increasing frequency on high-demand routes, expanding seven-day service, improving reliability through shorter and more direct routes, and strengthening connections to jobs, healthcare, and neighborhoods. The result: 99.4% of current riders would continue to have fixed-route service within a quarter mile of their existing bus stop, on a network that delivers more than today's with the same resources.
Rather than spreading service thinly across underutilized coverage, the Proposed Final Network focuses resources where transit is working and where riders depend on it most. This approach improves overall service quality while staying grounded in financial and operational realities.
Public feedback on the first draft of Bus Line Redesign made one thing clear: too much change was proposed and too quickly. Riders and operators emphasized the importance of maintaining service that worked and improving what didn’t.
BLR reflects what we heard. High-ridership corridors remain the backbone of the system. Direct service is restored to several communities. Route naming and structure more closely resemble the current network, making the system easier to understand and navigate. The refreshed network operates a similar number of peak routes as today, while improving service during midday, evenings, and weekends.
This is modernization with continuity.
The Proposed Final Network shifts service toward when riders are traveling. Saturday, Sunday, and weekday service increase. More routes run every 30 minutes or better — increasing from 27 routes today to 43 — and every route in the network operates at least hourly. The plan also establishes a frequent network of 19 routes running every 20 minutes or better during weekday peak hours across Allegheny County, up from 11 today — and overlapping routes create even more frequent corridors.
Shorter, straighter routes improve on-time performance by limiting the ripple effects of delays. Higher frequencies cut wait times and make transfers more reliable. Together, these improvements create a network that's easier to use and more dependable throughout the day — not just during peak commuting hours.
Equity is central to BLR’s decision-making framework. Service planning is guided by PRT’s Equity Index of Mobility Need, which prioritizes neighborhoods with higher transit dependence and fewer transportation options.
Under the proposal, 195,000 residents in equity communities* would gain access to 30-minute or better service, a 28% improvement. Nearly 380,000 job locations would be accessible at that same level of frequency — meaning thousands more jobs would be served by 30-minute or better service than today. More than 99.2% of current riders retain access within walking distance of transit.
These outcomes reflect a deliberate strategy to align service with both demand and need.

Bus Line Refresh improves service quality, strengthens connections, and makes more strategic use of limited resources while maintaining flexibility for the future. It demonstrates that PRT can deliver more frequent and reliable service with current funding, use data and public input to guide decisions, and build a stronger foundation for future investment.
Stable state funding remains essential to sustaining and expanding these improvements. If additional resources become available, the refreshed network is well-positioned to grow.
Now is the right time to update the bus network so it works better for how people travel today and is prepared for tomorrow.
Improve service quality and reliability by streamlining routes, making routes more direct, and improving on-time performance.
Prioritize equitable service by aligning routes with land use and socio-economic changes since our network was created, better serving transit-dependent and vulnerable riders.
Expand transit connections to major job centers, healthcare facilities, shopping centers, and between neighborhoods.
Metrics shown above are based on service proposed during the midday on weekdays.
Bus Line Redesign is more than a route plan, it includes a number of other improvements to make the system better for our riders. Learn more about these other components of the project below.
Bus Line Refresh creates a more connected bus network that provides riders new opportunities to make connections without having to travel to Downtown Pittsburgh. PRT’s existing transit hubs downtown, along the busways and light rail system, and at McKeesport Transportation Center, provide shelters, seating, and lean rails that support a more comfortable transfer experience. PRT envisions expanding this system of transit hubs to a broader network of bus stops throughout Allegheny County where riders can transfer between three or more routes that intersect from different directions. These bus stops would be prioritized for added improvements. Based on rider demand, PRT may roll out the service connections first, while it works to install shelters, seating, and other features as funding and property availability allows.
Bus stop balancing refers to strategically locating bus stops at key locations that riders need to access but at distances that allow buses to move efficiently. PRT’s current system has a high number of bus stops which can slow buses down in some locations. As PRT makes changes proposed in Bus Line Refresh, PRT will continue to identify opportunities for bus stop balancing on a route-by-route, case-by-case basis. With challenging topography, street network, and historical transit system, great care is needed when changing bus stops. New service areas proposed in Bus Line Refresh will aim to place bus stops consistent with PRT’s Bus Stop and Street Design Guidelines.
Route Names and Numbers: Familiar by Design
For most riders, the answer to "what happens to my route number?" is simple: almost nothing changes. Your route number still works the way it always has.
Earlier drafts of Bus Line Refresh tested a new lettering system that put prefixes in front of route numbers. Many riders and stakeholders told us that changing the routes and their numbers and names was too much change too fast. We listened. The Proposed Final Network drops the prefixes and keeps the historic numbering system riders already know.
Here's how naming and numbering work in the Proposed Final Network:
Every route has its own unique number. Routes follow PRT's historic geographic numbering system, and no two routes share a number. Today, branches like the 61A, 61B, and 61C share a number even though they serve different places — in the Proposed Final Network, each becomes its own distinct route, ending the misconception that every branch goes to the same destination.
Familiar suffixes stay, with the same meaning as today. "L" continues to mark commuter routes (like the 19L), and "X" continues to mark PRTX and airport routes (like the 28X).
Route variants are named by destination — just like today — rather than with letter suffixes.
Route names describe the area a route serves, not just its endpoint. For example, "59 Mon Valley" rather than "59 McKeesport" — a name that's more useful to more riders along the route and stays accurate over time.

PRT is committed to addressing the needs of riders and communities that are often underrepresented in transit planning. Equity has shaped decisions about route design, connections, frequency, and hours of service. This includes carefully evaluating how proposed changes may affect riders who rely on transit the most.
As part of this work, PRT reviews potential service impacts to help ensure that improvements do not disproportionately burden low-income riders, communities of color, seniors, people with disabilities, or households without access to a vehicle. More information about this analysis is available in the Equity Memo at BusLineDesign.com.
Equity also guides the public engagement process. This phase focuses on accessible outreach across neighborhoods, languages, and abilities to ensure all riders have meaningful opportunities to share input.
PRT is providing a variety of ways to participate, including in-person meetings, virtual sessions, and pop-up events designed to meet people where they are. All project materials and feedback opportunities are available in translatable and screen-readable formats, making it easier for riders with busy schedules or accessibility needs to contribute.
The project team will use this feedback to ensure that the updated network reflects the full diversity of riders and stakeholders, particularly those who rely on transit the most.

The Proposed Final Network is now in its formal public comment period, which runs through September 30, 2026. After the comment period closes, PRT staff will summarize all comments and report them to the PRT Board, who is expected to consider the plan for approval in November 2026.
If the Board approves the plan, PRT will implement the new network in the latter half of 2027. The months between Board approval and implementation are for preparation: scheduling, operator assignments and training, stop and signage changes, and a major rider education campaign to help everyone learn the new network before it launches.
As Pittsburgh Public Schools considers its consolidation plans, PRT will continue to coordinate with the district to understand which schools will remain open, what feeder patterns are being considered, and how a combination of transportation services including PRT can meet the needs of students and their parents. During this phase of engagement, parents and caregivers should use PRT’s network preview on the Transit App to understand how the proposed network would allow their students to get to any of the proposed schools.
BLR makes the most cost-effective use of PRT’s current funding, but will be unable to keep up with transit demand without additional funding. Click here to learn more about what PRT could do with a 20% increase in service hours.
