Keystone Bicycle Boulevard Project

North Kenneth - Winona Bicycle Boulevard Project

A Bicycle Boulevard is generally a low-traffic neighborhood street that has been optimized for bicycling. They provide direct attractive routes for cyclists, while also enhancing and improving the character of the neighborhood. This is accomplished by using a combination of Class III Bike Route and Share the Road signage, “sharrows”, and a variety of different traffic calming treatments. 


As all roadways and adjacent neighborhoods have different characteristics, each Bicycle Boulevard should individually address these differences. As a result, not all Bicycle Boulevard are the same, but rather “designed to fit”. However, the theme remains consistent.

What all Bicycle Boulevards share is commonly referred to as the “Toolbox”. This Toolbox consists of the various roadway treatments, or “tools”, which can be used to best enhance the roadway and neighborhood for both cyclists and neighborhood residents. The Bicycle Boulevard Toolbox breaks down as follows:

AUTO SPEED REDUCTION – Research shows that by limiting auto speeds to 25mph or less, the risk of collision, injury, or death is greatly reduced. The ideal car speed on bicycle boulevards is 15-20mph. The purpose of the tools in this section is to slow cars down on neighborhood streets making them safer for everyone. Examples include:

  • STOP SIGNS – Stops car traffic, oriented to favor cyclist traveling on bicycle boulevard
  • MINI TRAFFIC CIRCLES – Reduces auto speed, only within 100 feet of circle 
  • TRAFFIC ISLANDS – Reduces auto speeds as vehicles turn from major arterials to bicycle boulevard
  • MEDIAN ISLANDS – Reduces turning radii at intersections

AUTO TRAFFIC REDUCTION – The maximum average daily traffic (ADT) on a bicycle boulevard is 3,000 cars per day or less, preferably as low as 1,500 cars per day. When auto speed reduction is combined with auto traffic reduction or "diversion", safety on bicycle boulevards is maximized. Cars are still allowed on bicycle boulevards, but diversion treatments encourage them to drive on arterial streets instead of neighborhood streets when they need to get somewhere quickly. The tools in this section limit auto access to bicycle boulevards at critical points, while allowing bicycle traffic to get through. Examples include:

  • SEMI-DIVERSION – Limits auto access while allowing bicycle access
  • FULL-DIVERSION – Restricts auto access while allowing bicycle access

CROSSING BUSY STREETS – No bicycle boulevard is complete without closing the gaps. Large arterial streets, freeways and railroad tracks all create significant barriers for bicyclists, pedestrians, and neighborhoods. In order to have a working network of bicycle boulevards, it is imperative that cyclists are able to cross major intersections safely. Examples include:

  • HIGH VISIBILITY “ZEBRA” CROSSWALKS – Increases visibility at crossings
  • CURB EXTENSIONS – Increases bicycle/pedestrian visibility, shortens crossing distance
  • MEDIANS – Limits auto access, provides mid-point crossing refuge for bicycles/pedestrians
  • BICYCLE DETECTION – Cyclist can trigger traffic lights by placing tires over bike symbol. Signal will be actuated by camera or loop detectors.
  • BIKE BOXES – Brings cyclists to front of the line at traffic lights, priority crossing/turning, reduces right-hook conflicts, as needed filling in the box with color paint can further increase visibility

BOULEVARD SIGNAGE AND MARKINGS – Along a Bicycle Boulevard signage and markings are enhanced beyond the standard Class III Bike Route signage. Smaller markings on the ground tell cyclists where to go while larger markings indicate to drivers that they are on a bike boulevard and should slow down. Signs tell cyclists where they are headed and how much further they have to go to reach their destination. The tools in this section offer a few examples of ways to show cyclists and community residents how to get from here to there.

  • SHARROWS – “Share the Road” arrow. Indicates that cyclist can use the whole lane. Marking designed so if you ride down the center of the arrows, you will be outside the "door-zone”
  • WAY FINDING SIGNAGE – Indicates distance to certain districts, gives direction and travel time
  • SHARE THE ROAD SIGNAGE – Indicates to motor vehicle drivers that cyclists may be present
