City of Wheat Ridge W 35th Avenue Traffic Improvement Plan Final Design Scope of Work – June 1, 2026

INTRODUCTION

The 35th Avenue neighborhood bikeway in Denver now ends at Sheridan Boulevard, leaving a critical gap in bike infrastructure between Sheridan and Wadsworth Boulevard. This corridor is also a key pedestrian route, providing access to amenities like Panorama Park, Founders Park, the Active Adult Center, and the Wadsworth Urban Center. Unfortunately, many sidewalks along this stretch are inadequate or non‐existent, forcing pedestrians to walk in the street—creating dangerous conflicts with both cyclists and vehicles. The 35th Avenue Multimodal Improvement Project will address these issues and enhance safety and accessibility for all users.

BACKGROUND

The 35th Avenue Multimodal Improvements project will establish a 1.5-mile multimodal corridor connecting Sheridan Boulevard to Wadsworth Boulevard. This segment will extend the existing 35th Avenue neighborhood bikeway in Denver to reach the Wadsworth Urban Center, providing essential pedestrian and bicycle accesses, especially valuable since the east end of the current bikeway lies just blocks from both the Denver Central Business District and the 41st & Fox Transit-Oriented Development.

By bridging this gap, the project will create a vital non‑motorized connection between western and central Denver and Wheat Ridge. It enhances access to pedestrian-focused zones near 35th & Wadsworth and lies within three blocks of the 38th & Sheridan pedestrian district. Along the route, improved multimodal access will benefit key destinations like two parks and Wheat Ridge’s Active Adult Center.

Critically, the improvement links to the shared-use trail under construction along the east side of Wadsworth, which connects to the Clear Creek Trail—part of the broader Peaks-to-Plains Regional Trail System. It also ties into the Pierce Street bike lanes, offering further connectivity north and south to the 32nd Avenue Regional Bikeway, 26th Avenue bike lanes, and onward into Lakewood acppubs.com.

Nearly 24,000 residents within the project area will benefit from increased safety and improved connectivity, linking them to multiple regional multimodal routes. The corridor enhancements also include traffic-calming features aimed at reducing speeds and prioritizing safe, shared use.

This initiative builds upon the current Denver multimodal corridor ending at Sheridan by extending infrastructure to Wadsworth and directly serving the Wadsworth Urban Center in Wheat Ridge. Meanwhile, a shared-use path is already under construction between 35th Avenue and the Clear Creek Trail, integrating the corridor into the regional trail network and facilitating inter-subregional access across Jefferson County and Denver.

PAST PLANNING EFFORTS Comment by Ashley Holland: Added the section below.

Improvements to W 35th Avenue between Sheridan Boulevard and Wadsworth Boulevard have been identified as a community priority through multiple planning and engagement efforts over the past several years. In 2017, the city’s Bicycle and Pedestrian Master Plan designated this segment of W 35th Avenue as a Neighborhood Bikeway and recommended improvements including pavement markings, signage, traffic calming measures, crossing enhancements, and wayfinding elements to improve multimodal safety and connectivity.

In 2020, residents reaffirmed the need for corridor improvements through the city’s neighborhood engagement program, Let’s Talk East Wheat Ridge. Community input gathered through that process led to the launch of the W 35th Avenue Street Improvements project in 2022, which focused on identifying neighborhood priorities and desired corridor enhancements. More than 240 area residents participated in the engagement process. Key themes that emerged from community feedback included:

· Concerns about vehicle speeds and traffic safety along the corridor

· Prioritizing safer conditions for pedestrians, bicyclists, and individuals using mobility aids

· A strong desire for continuous and connected sidewalk infrastructure Most recently, the 2025 City Plan identified W 35th Avenue between Sheridan Boulevard and Teller Street as a Neighborhood Bike Connector. This designation calls for implementation of the best feasible bicycle facility to improve east-west connectivity. Improvements may include bike lanes, traffic calming measures, shared lane markings, signage, and related multimodal safety enhancements.

Together, these planning efforts and community engagement initiatives have established a strong foundation for the current final design process.

SCOPE OF WORK Comment by Lauren Mikulak: Did the TIP or funding agreement specific sidewalk widths? Comment by Logan Huffaker: @Lauren Mikulak I haven’t seen anything specifying sidewalk widths. Should we go with our typical section with 5ft attached or 6ft detached? Comment by Lauren Mikulak: It would be 5 foot attached I think if we’re also trying to fit in bike facilities The City seeks the Consultant’s expert guidance in shaping a varied and context-sensitive corridor along 35th Avenue, extending the neighborhood bikeway from Sheridan Boulevard to Wadsworth Boulevard. This project must integrate three key elements—traffic calming, bicycle infrastructure, and pedestrian amenities—adapted to local conditions and community input.

· Corridor Tailoring: Recognizing diverse conditions and feedback from residents along the route, the design will be customized. In zones with higher activity—such as parks, major walking destinations, and higher-traffic areas, the focus will be on installing 5 foot wide attached sidewalks and sharrows (shared-lane markings).

· Strategic Flexibility: In less-traveled or more constrained segments, where right-of-way or property access is sensitive, the use of advisory shoulders will be considered. This approach preserves access to adjacent properties while promoting multimodal use and minimizing potential impacts.
