Big Things Littleton

Thanks to voter support of the 2021 Ballot Issue 3A, which raised funds for an increased pace of capital projects, the City of Littleton has completed or is nearing completion on many large-scale road and infrastructure upgrades.

For the most current information on construction, improvements, and investments being made in the city, visit the Public Works Projects page.

Current Projects

• The Santa Fe and Mineral Improvements Project began construction in spring 2026 and will continue into 2027. The project 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.
• The Mineral Mobility East Improvements Project Phase 1 construction was completed in spring 2026. The project provides 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. Mineral Mobility East Improvements Project Phase 2 design is underway with construction anticipated in 2027. Phase 2 includes improvements to the Mineral Avenue and Jackass Hill Road/Long Avenue intersection and the Mineral Avenue Trail west of Jackass Hill Road.
• The Euclid Avenue Multimodal Improvements Phase 1 was completed in 2025. Phase 2 construction began in summer 2026. The 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.
• The Mineral & Platte Canyon and Bowles & Platte Canyon Intersection Improvements Project construction is anticipated to be completed in summer 2026. The 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 Prince Street Link project construction is anticipated to begin in summer 2026. The 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.
• The Euclid Neighborhood 2026 Street Reconstruction project is anticipated to begin in summer 2026. The project will reconstruct several streets 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.
• The City of Littleton continues to implement 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.
