Washington Street Corridor

The Washington Street Corridor improvements are made up of two major projects, The Washington Street (47th to 52nd avenue) project and 51st Avenue (Washington to Logan streets) project. 

About the Project (47th Ave to 52nd Avenue Safety Improvements)

The City and County of Denver and its contractor started the Washington Street 47th to 52nd Improvements Project in February 2026. The project will enhance this section of the Washington Street corridor by creating a mixed-use riverfront destination with connections to the South Platte River and the National Western Center. Improvements include full-depth street reconstruction and widening; new travel lanes and on-street parking; multi-use sidewalks; upgraded sewer and storm drainage systems; and new traffic signals, lighting and landscaping. The project is funded by the 2021 Denver bond. 

About the Project (51st Avenue)

The City and its contractor are currently working on the 51st Avenue Safety Improvements project between Washington Street and Logan Street to enhance safety, mobility and roadway conditions. Work includes roadway reconstruction, intersection upgrades and utility coordination, with construction occurring in phases to minimize disruptions. Traffic impacts such as lane shifts, lane closures and occasional full closures are expected during construction. Once complete, the project will provide a safer and more reliable corridor for drivers, pedestrians and cyclists while improving overall neighborhood connectivity.

Timeline 

Washington Street: February 2026 - Fall 2027

Study Archive

Vision: The area is transformed into a mixed-use riverfront destination area that capitalizes on its adjacency to the South Platte River, a revitalized Washington Street, reinvented greenspace, and direct connections across the river to the National Western Center.

Goal Statement: Make Washington Street an attractive corridor that creates a positive sense of place, attracts private reinvestment, and better accommodates all transportation modes.

Study Goals

Washington Street was identified in the Globeville Neighborhood Plan as “an attractive corridor that creates a positive sense of place, attracts private reinvestment, and better accommodates all transportation modes.” The Washington Street Study will refine and progress this vision of Washington Street into an implementable conceptual design.

Challenges along Washington Street include the existing right of way width of 60 feet and the inconsistency and poor condition of the curb, gutter and sidewalk to provide definition and separation between vehicular travel and pedestrian space. Intersection capacity, multi-modal connectivity and water quality infrastructure needs are additional challenges along the street.

Multimodal connections for the Washington Street corridor as well as the adjacent corridors will also be considered to integrate the street into a larger surrounding context.

Study Map & Limits

The study limits start at the South Platte River and extend north to the City and County of Denver municipal boundary limits near 52nd Avenue. The analysis, planning and conceptual design will address the changing land uses and the future vision for the corridor as a mixed use street, as previously identified in the Globeville neighborhood Plan.
