Big Things Littleton

Welcome to Big Things Littleton: The source for the most up to date information on construction, improvements, and investments being made in the city.

Introduction

Thanks to voter support of the 2021 Ballot Issue 3A, which raises funds for an increased pace of capital projects paving the way for transportation improvements, economic growth, and innovation, Littleton’s public works team is gearing up for a busy year of large-scale road and infrastructure upgrades.

Keep an eye out for detours and give crews space on the roadway.  Check here for latest updates. 

Here is a look at what is coming in 2025:

• The Santa Fe and Mineral Improvement Project is scheduled to begin construction late spring and will reduce congestion and improve safety with a realignment known as a quadrant roadway. This project will remove left-turn movements from the intersection, allowing for more “green time” at the traffic signal. The project will provide new traffic signals, lane configurations, signal re-timing and mobility improvements at this intersection and surrounding areas. This will be the largest scale construction project within the city in the past several decades continuing through 2026 and potentially into 2027.
• The Mineral Mobility East Improvements Project Phase 1 will begin this spring, to provide safety and mobility upgrades along Jackass Hill Road, Mineral Avenue, and the Mineral Avenue Trail. The project includes upgrading existing bike lanes to buffered bike lanes, paving and providing designated space for pedestrians and bicyclists along the all-season Mineral Avenue Trail, and improvements to two of the High Line Canal Trail crossings in the area. The work is anticipated to be completed this fall.
• The Euclid Avenue Reconstruction Project will bring “complete street design” components to West Euclid Avenue between South Elati Street and the High Line Canal, part of the Safer Streets Littleton initiative. Design elements include a 12-foot-wide shared-use path along the north side of the corridor, widened sidewalks along the south side, three raised pedestrian crossings, curb extensions at intersections, and other traffic-calming elements. For more information, visit LittletonCO.gov/SaferStreets.
• The Mineral & Platte Canyon and Bowles & Platte Canyon Intersection Improvements Project focuses on the intersections of South Platte Canyon Road with West Mineral Avenue and West Bowles Avenue. The project will enhance pedestrian and bicyclist safety with new crossings, resolve traffic conflicts with expanded turn lanes, improve bus stop access with pedestrian ramps, and upgrade signal equipment. The project is scheduled to begin in March 2025.
• The Prince Street and Church Avenue Intersection Reconstruction project will improve deteriorating infrastructure at the intersection of South Prince Street and Church Avenue with improvements to sidewalks and ramps, as well as pedestrian and vehicular signals to ensure compliance with ADA guidelines. Additionally, the work will replace concrete and asphalt through the intersection, upgrade guardrails, and improve landscaped shoulders. Project activities are scheduled to start in summer 2025.
• East Euclid Avenue between South Gallup Street and South Windermere Street and several adjacent streets will be reconstructed this summer to create  a stronger, smoother driving surface. This project will also create a safe and accessible pedestrian route on the northern side of Euclid Avenue, as well as connecting sidewalk gaps on several streets running north to south. This project will begin in mid-summer.

Safer Streets Littleton 

The City of Littleton is embarking on Safer Streets Littleton, an ambitious effort to improve pedestrian and bicyclist safety through an accelerated pace of infrastructure upgrades, increased traffic enforcement, and public education.   

City council has directed the Public Works Department to prioritize and accelerate related projects. City officials are coordinating with Littleton Public Schools to ensure effective implementation of traffic safety measures. Public Works has added two new positions in 2024 to help address the increased pace of work.

A recap of some of the work that was delivered in 2024:

• A new trail along W. Crestline Avenue in Geneva Park was constructed. This is the first phase of the trail along Slaughterhouse Gulch that will connect the Mary Carter Greenway to the Community Trail. 
• Damaged concrete infrastructure was removed and replaced at numerous locations citywide, prepping for the to mill and overlay asphalt road surfaces this year in 2025. 
• Mill and overlay work was completed in the Arapaho Hills, Centennial Acres, Happy Homes, and Aberdeen Village neighborhoods. 
• Deficient joints on the W. Mineral Avenue bridge over the South Platte River were replaced, smoothing the roadway for motorists.  
• Numerous bicycle and pedestrian safety projects citywide as part of Safer Streets Littleton, including new crosswalks near schools, speed feedback signs along several corridors, school zone traffic control device upgrades, bicycle and pedestrian quick-build and pilot projects, and ongoing traffic safety studies. 

2023 Recap 

It was a BIG year for capital and infrastructure improvements, thanks to additional sales tax revenue collected over the past two years. While the work will continue, here’s a recap of some of the projects that have been completed or are near completion:

• Construction of three raised pedestrian crossings downtown.
• Roughly 25 miles of pavement preservation. View the map of the planned streets(PDF, 4MB) and watch the “Around Town with Jim” video to learn more about this project.
• Replacement of traffic signal systems at nine intersections along S. Broadway, W. Bowles Avenue, and S. Mineral Avenue
• Hot in-place recycling (a process that rehabilitates asphalt) along W. County Line Road
• Aberdeen Village drainage, including replacing/installing storm sewer and inlets at intersections of S. Longview Street and S. Lakeview Street, and S. Lakeview Street and W. Aberdeen Avenue.
• Mill and overlay (a process that involves grinding up existing asphalt and applying new material) in Happy Homes and Aberdeen Village neighborhoods
• Installation of fiber optic communication for traffic signal systems along S. Broadway between W. Powers Avenue and W. Arapahoe Road. View the phase 1(PDF, 342KB) and phase 2(PDF, 289KB) maps.
