W 57th Avenue Study background

The City is studying the W 57th Avenue corridor from Garrison St to Upham St and a small section of Grandview Ave from Independence St to Garrison St.

The study is looking at ways to improve mobility and safety along the corridor for people bicycling, walking, and driving. The 2017 Bicycle Masterplan identified this corridor as the most important bike route in the city and this corridor study is the next step in developing improvements in this area.

We are engaging the public to provide feedback on issues, potential solutions, and ideas to enhance this corridor for everyone. Please provide input through our interactive map, survey, and/or email.

The study is planned to be completed by the end of 2020 with the recommendations moving into design in 2021.

*September Update-Public Comment Period now Closed* Three Alternatives Proposed for Public Feedback

Below you will find information related to the three alternatives proposed to improve safety in this corridor, with a focus on bicyclists and pedestrians. The Project board below shows a variety of recommendations to slow vehicle speeds, separate bike lanes from vehicles, and/or widen sidewalks. The final recommendation may be a combination of these alternatives based on public feedback. The core focus of each alternative is summarized below. You can provide feedback to the project team via the interactive map, survey, and e-mail: pw_workzone@arvada.org.

Grandview Avenue: Independence St to Garrison St

Option A: Traffic calming and intersection improvements. This option recommends installing several traffic calming devices to reduce speeding vehicles. It also involves making changes at the intersection of Independence St to make the crossing more comfortable.

Option B: Traffic Calming + New Trail: This option includes the traffic calming, but would also repurpose parking on the south side of the street to widen the sidewalk to a 10’ wide trail with a landscaped buffer. This would be an extension of the Van Bibber Creek Trail. In the interim, the existing parking spaces would be repurposed to an eastbound bike lake to accommodate bicyclists.

Garrison St: Grandview Ave to W 57th Ave

This small segment of roadway is comfortable as is and a speed study did not identify a speeding issue on this section of roadway. Bicycle way finding signage will be added to direct bicyclists between W 57th Ave and Grandview Ave.

W 57th Avenue: Garrison St to Webster St

Option A: Traffic Calming and Speed Reduction. Option 1 utilizes a variety of traffic calming devices including speed cushions, curb extensions, raised crosswalks, and traffic circles to slow vehicles speeds. The speed limit is proposed to be reduced from 30mph to 25mph from Balsam St to Independence St.

Option B: Traffic Calming + Bicycling Focus. Option B builds on Option A by adding separated bike lanes from Garrison St to Balsam St, and standard bike lanes from Balsam St to Olde Wadsworth Blvd, in addition to the traffic calming devices. Separated bike lanes are physically separated from travel lanes by a barrier. This option requires repurposing the parking spaces on the south side of W 57th Avenue for the bike lanes from Garrison St to Olde Wadsworth Boulevard. Parking would remain available to the public on the north side of the street.

Option C: Traffic Calming + Walking focus. Option C builds on Option A by constructing detached sidewalks in addition to the traffic calming devices, and improving the existing bike lanes between Garrisons St and Balsam St. The current sidewalks are narrow, do not meet width requirements per the Americans with Disability Act (ADA), and have curb ramps that need to be updated to meet ADA requirements. This option requires repurposing the parking spaces on the south side of W 57th Avenue to widen the sidewalk and add a landscaped buffer from Garrison St to Olde Wadsworth Boulevard. Parking would remain available to the public on the north side of the street.

The concept plan below shows the recommended traffic calming features, as well as cross sections along Garrison St and the different options for W 57th Avenue described above. You can download a PDF of these concepts from the Documents section on the right to view them in more detail. --------------------------------------------------------------------------->

Study Corridor - Issues and Concerns

about 1 month

You can use this interactive web map to pinpoint any locations where you have noticed an issue or have a concern related to bicycling, walking or driving. We will use this information as we continue the study and make decisions about what locations need improvements, and which improvements we will recommend.

CLOSED: This map consultation has concluded.

Crossing Improvement-Blue

At Field St, Balsam St, and Allison St, there are two types of traffic calming options shown, but only one will be implemented.

At the intersection of Grandview Ave and Independence Ave both improvements  could be implemented: one across Grandview Ave and one across Independence Ave.

At the intersection of W 57th Ave and Garrison St all three improvements could be implemented.

At the intersection of W 57th Ave and Upham St both improvements could be implemented.
