How to find bike-friendly roads

Car navigation looks for the fastest way. A good cycling road is often the opposite: slower, quieter, with room at the edge. Here is what to look for, and where to check it before you ride.

The three things that make a road good to ride

1. Room at the edge: shoulder or bike lane

A paved shoulder gives you somewhere to be when a truck passes. Road design guides treat 4 feet of paved shoulder as the minimum that really works for bikes. Two feet helps a little; a painted edge line with nothing outside it is no shoulder at all. Watch for shoulders that come and go: many roads have a good shoulder between towns and none through the bridges and intersections, where you need it most.

2. Traffic: speed first, then volume

A 25 mph street with steady traffic is often easier to ride than a 50 mph county road with a car a minute. Speed limits, the number of lanes and the road's class (local street, collector, county route, state highway) tell you most of it. Roads that link two highways or lead to a shopping center tend to be busy at every hour.

3. Pavement

Potholes, patched trenches, broken edges and rumble strips in the shoulder turn a quiet road into a bad one. Pavement changes faster than maps do: a road repaved last summer and one due for repaving next year look the same on a map.

Where to check before you ride

Street View. The best single check for shoulders and pavement. Look at the date on the image: a few years old can mean a different surface today.
Satellite view. Shows shoulder width and edge lines along a whole road quickly. Zoom in at the bridges and intersections.
OpenStreetMap. Mapped bike lanes, signed bike routes and road classes. Cycle maps like CyclOSM draw them. Shoulder tags are often missing, so a road with no tag isn't necessarily a road with no shoulder.
State road surveys. Many state transportation departments publish lane and shoulder widths for the roads they track. New Jersey's NJDOT, for example, has measured shoulder widths for county routes, mile by mile.
Popularity heatmaps. Where other cyclists ride is a useful hint, but popular isn't the same as safe: a road can be busy with bikes because it's the only way through.
Local clubs. Club route libraries are written by people who ride those roads every week.

Riding the roads you can't avoid

Sometimes the only way out of a neighborhood is a busy road without a shoulder. Keep that stretch short, ride it at quiet hours, use a daytime rear light, and ride far enough out in the lane that drivers have to pass properly instead of squeezing by. In New Jersey, the Safe Passing Law (2022) requires drivers to change lanes to pass a cyclist when they can, give at least 4 feet when they can't, and slow to 25 mph when neither is possible.

How RideLoop does this for you

RideLoop grades each road on a loop for pavement, shoulder and traffic, from satellite and street-level photos, and adds state survey data where it exists. Grades are shared, so every rider's loops make the map better for the next. Loops are built from graded roads: state highways and fast roads are left out, shoulderless county roads are used only as short connectors, and roads you mark rough are avoided.
