Biking in Littleton

Littleton aims to provide people of all ages and abilities, and in all areas of the city, with a bicycle network that is safe, comfortable, and connected. Our goals are to provide people with healthier and more affordable travel choices that get them where they want to go.

By implementing protected infrastructure for people on bicycles, Littleton is creating safer streets for everyone by building streets with slower speeds, safer intersections, better connections to transit, and safer conditions for drivers.

Data Summary

Street Type: Neighborhood Connector
Speed Limit: 25 MPH
Average Daily Traffic (ADT): 1,428
85th Percentile Speed: 37 MPH
Serious Injury and Fatal Crashes since 2022: 0

Planned Improvements

Upgrading to protected bike lane using “Zebra” lane separators and delineators and installing speed cushions for traffic calming.

Data Summary

Street Type: Neighborhood Connector
Speed Limit: 30 MPH
Average Daily Traffic (ADT): 3,000
85^th Percentile Speed: 24 MPH
Serious Injury and Fatal Crashes since 2022: 0

Planned Improvements

Upgrading to protected bike lane using rubber parking stops and delineators. On-street parking along Pennsylvania Street between Mineral Avenue and Nichols Drive will be removed to accommodate the protected bike lane. Field users are encouraged to use the available parking lots at Powell Middle School once this infrastructure is installed.

Data Summary

Street Type: Neighborhood Connector
Speed Limit: 30 MPH
Average Daily Traffic (ADT): 16,447
85^th Percentile Speed: 34 MPH
Serious Injury and Fatal Crashes since 2020: 0

Planned Improvements

Upgrading to protected bike lane using lane separators along Windermere Street between Sheri Lane and Layton Avenue. Additionally, a protected bicycle intersection at Windermere Street and Belleview Avenue will be installed; protected intersections physically separate people walking, biking, and rolling from vehicles up to and through the intersection and make it easier for these travelers to see and be seen by drivers.

FAQs

Why was my street chosen for one of these projects?

The City selects locations for protected bike lanes based on a combination of factors, including the following:
- Speed and Traffic Data - Streets with high vehicle speeds or traffic volumes may be prioritized to improve safety.
  Planned Roadway Improvements - Locations scheduled for repaving or restriping provide an opportunity to test safety enhancements efficiently.
- Crash History- Areas with a history of crashes, particularly those involving people walking and biking, may be chosen for safety interventions.
- Roadway and Land Use Context - Factors such as street width, number of lanes, nearby schools, parks, or businesses influence project selection.
- Community Feedback - Input from residents and stakeholders helps identify areas where safety concerns exist.

How long will construction last?

Because the City uses quick-install materials for these projects, construction is typically completed within a few days. Larger projects, such as those spanning an entire corridor, may take multiple weeks. However, timelines can vary depending on weather conditions. The City's goal is to minimize disruption while making safety improvements as efficiently as possible.

Why does the City use plastic and rubber materials instead of concrete for these treatments?

The materials the city uses for pilot projects are quick to install and moveable if we need to make revisions to the project design, all at a much lower cost than using concrete. These materials can be installed by City staff in a matter of days, as well as temporarily removed, if necessary, due to emergencies, heavy snow, or other conditions. Just like a seamstress would use a lower cost fabric to test how the project fits and adjust as needed before investing in a more durable, high-quality fabric, the city is first using lower-cost, quick-to-install materials to test and refine the design and materials before seeking to make them permanent.
