Build It and They Will Ride: New Research Proves Cycling Infrastructure Actually Works

The chicken-and-egg debate about cycling infrastructure has been running for decades. Do you build bike lanes because people want to cycle, or do people start cycling because you built the lanes? The advocacy position — build it and they will come — has always had intuitive appeal but frustratingly mixed evidence to back it up. A major study published in August 2026 has added some of the sharpest data yet to one side of that argument.

The findings, released in the second week of August, provide some of the clearest evidence to date that building better cycling networks can meaningfully increase bike commuting — but with a critical caveat about where cities build that infrastructure and how well it connects.

What the Research Found

The core finding is not simply that infrastructure increases ridership — it's that connected infrastructure increases ridership. Isolated segments of protected lanes that don't link to meaningful destinations, residential areas, or broader networks produce weak ridership gains. Contiguous networks that give a rider a complete, low-stress route from home to work or school produce dramatically stronger responses.

This distinction is crucial for understanding why some cities have seen cycling modal share grow rapidly while others have spent heavily on infrastructure with limited results. The difference often isn't the quality of the individual lanes — it's whether those lanes form a functional network or exist as isolated green paint.

The research supports a growing consensus in transport planning: network completeness is the variable that matters most. A single protected lane on a major road is a start. A connected grid that a rider can navigate without ever mixing with high-speed traffic is a different product entirely — one that unlocks cycling as a genuine transport option for people who currently don't ride.

Money Is Moving — In Multiple Directions

The research arrives at a moment when infrastructure funding decisions are being made at multiple levels of government simultaneously, with results that range from encouraging to concerning.

In Canada, concrete progress is happening. Ottawa announced this week that over $5.1 million in federal investment will create new cycling facilities along Orléans Boulevard and Jeanne d'Arc Boulevard, with separated infrastructure for cyclists and pedestrians designed to connect residential neighbourhoods with commercial corridors. It's exactly the kind of network-completion investment that the new research suggests produces real mode-shift.

In Sydney, a new cycling and pedestrian bridge crossing Manly Lagoon at Queenscliff opened this week, adding another piece to the Northern Beaches cycling network in a region notorious for traffic congestion and limited parking. Bit-by-bit infrastructure addition in a high-density coastal zone — but the cumulative effect is starting to look like a real network.

In Europe, the picture is ambitious. From 2026, €87 billion from the EU Social Climate Fund becomes available for targeted purchase subsidies, cycling infrastructure projects, and bike-sharing schemes — a funding level that dwarfs any previous European cycling investment and one that the European Cyclists' Federation has been advocating for intensively.

The US Picture: Mixed Signals

North of the Rio Grande, the US infrastructure funding picture is murkier. The House Transportation and Infrastructure Committee approved the BUILD America 250 Act, a five-year surface transportation reauthorisation bill that carries mixed news for cyclists. On the positive side, the bill allows up to a 10% increase in funding for Transportation Alternatives — a programme authorised at slightly under $1.5 billion annually. The Congestion Mitigation and Air Quality Programme, which funds some cycling projects alongside air quality measures, would also see a small bump to approximately $3 billion per year.

The downside is more significant. The Safe Streets and Roads for All Grant Programme — which provides planning and implementation grants for safety projects — would be cut from $1 billion annually to $500 million in FY 2027, before ramping back up to $1 billion by FY 2031. The Active Transportation Infrastructure Investment Programme, which provided competitive grants specifically for safe and connected active transportation infrastructure, would be eliminated entirely.

The Senate has not yet moved a competing version, and surface transportation law expires on September 30 — meaning Congress may simply extend current law rather than pass new legislation in the near term.

The Connectivity Imperative

What ties all of these developments together is the research insight: connectivity determines outcomes. Investing $5.1 million in a connected corridor produces measurably different ridership outcomes than spending the same money on fragmented improvements. The EU's €87 billion fund will generate cycling gains in cities that spend it on network completion — and minimal gains in cities that use it for showcase infrastructure that doesn't connect to anything.

For advocates, the 2026 research is useful ammunition precisely because it moves the conversation beyond "build lanes" to "build connected lanes." Network design, destination access, and low-stress routing are the variables that convert infrastructure investment into actual riding.

What This Means for Your Riding

If you commute by bike — or want to — the most effective thing you can do beyond riding is to engage with your local planning process when cycling networks are being designed. Specifically, identify the gaps in your city's existing network: the junctions where the protected lane disappears, the arterials that don't have any cycling provision, the bridges that are pedestrian-only. These gap points are where advocacy energy has the most direct impact. The research is increasingly clear that network completeness is the lever. Push on that lever.
