Transportation Projects

State Hwy 7 & 119th Street Intersection Improvement Project

Beginning in November 2023, the City will partner with the Town of Erie, the Boulder County Transportation Department, and the Colorado Department of Transportation on a project to enhance multimodal safety and accessibility at the intersection of State Highway 7 (SH 7) and 119th Street.

This project will advance commuting and multimodal improvements such as the widening of 119th Street at SH 7, improved drainage, dedicated right and left turn lanes, future transit lanes, new sidewalks, signalized crosswalks and dedicated bike lanes.

South Boulder Road Multimodal Improvement Project

The Project will enhance safety and multimodal travel for all users along this corridor. Work includes improvements to South Boulder Road, between the Saratoga/Merlin Drive intersection and 120th Street, with minor work on City Center Circle and on 120th Street, between approximately Eastwind Drive and Coal Creek. 

Enhancements include bike lanes, a new 6-foot wide sidewalk on the north, a new 10-foot wide multi-use path along the south, reconstructing the LaMont Does Park parking lot, burying overhead power lines, a new signalized and widened intersection at 120th St., improving drainage, and the replacement of an aging water line.

East Emma Street Improvement Project 

New and improved roadway and service infrastructure is planned for East Emma Street adjacent to the new Willoughby Corner affordable housing development. For the next several months, Boulder County Housing Authority will be reconstructing East Emma Street from Burlington Avenue to 120th Street, upgrading and relocating the waterline,  replacing the sanitary sewer line, installing a roundabout at Canterbury Drive, and installing a traffic signal at East Emma and 120th Street.

Transportation Plans and Studies

Lafayette Multimodal Transportation Plan (MMTP)

The City's first-ever Multimodal Transportation Plan (MMTP) is underway. We are in the process of analyzing relevant data and gathering community input to understand the existing and future conditions of multimodal transportation and mobility in and around Lafayette. 

The project team will consider existing and planned future land uses, traffic operations, safety, access, mobility, and connectivity of all transportation modes such as walking, biking, transit, and driving. The MMTP is being completed in close coordination with local and regional plans and projects, including the City’s Comprehensive Plan.

The results of this multimodal analysis, in addition to community and stakeholder input, will help to identify the transportation needs of the City and develop near- and long-term actions and solutions to preserve and improve the City’s transportation system.

South Boulder Road Corridor Study

The Denver Regional Council of Governments (DRCOG) is leading the South Boulder Road Study in partnership with Boulder County, the cities of Boulder, Lafayette, Louisville, and the Regional Transportation District (RTD). The goal is to develop a shared vision for the corridor by identifying current safety and mobility challenges and future opportunities to make the corridor more accessible for all road users.

CO7 Multimodal Corridor: Boulder to Brighton

The purpose of this project is to improve traveler safety, improve personal travel efficiency and operations, and improve access to multimodal travel along a nearly 25 mile stretch of Colorado State Highway 7 (CO 7) between Brighton and Boulder.

Multiple planning and feasibility studies have established the corridor’s future multimodal vision, including an integrated plan of Bus Rapid Transit (BRT) improvements supported by multimodal (roadway, bicycle and pedestrian) infrastructure and transit supportive land development at planned station areas. Priority projects are being identified and preliminary design plans developed to encourage quick investment in the transportation improvements amongst the municipalities, counties, agencies and developers along the corridor.

US Highway 287 Corridor Planning - Vision Safety and Mobility Study

Boulder County, in coordination with stakeholders, regional partners and members of the public, is conducting a multi-phased re-envisioning process. This first phase of the study, closely examines the feasibility of Bus Rapid Transit (BRT) implementation on the US 287 corridor between Longmont and Broomfield to address the growing congestion and travel demand in the area. 

The study will recommend the type and location of capital investments that will enhance transit travel times on US 287 through conducting an analysis that will assess traffic patterns, current transit operations and infrastructure, vehicle queue lengths, opportunities for intersections treatments, and a Station Areas Toolkit.

Safe Streets for All Grant

As a result of grant funding awarded in March 2023, Lafayette has initiated a collaborative effort with Boulder County to develop a comprehensive safety action plan. This will process determine what safety issues exist in the City, including identifying high injury networks and major collision or injury trends. This study will identify safety priorities that will drive future funding and staff resources, will set up Lafayette to collaborate with Boulder County on future Vision Zero efforts, and identify what resources Lafayette may need to adopt a Vision Zero action plan. Most components of this work effort should take 12 months to complete. View the grant press release from Rep. Neguse's office.

Future 42 Corridor Plan

The Cities of Lafayette and Louisville are working together to envision the future of State Highway 42 (also known as 95th Street, CO-42, or Courtesy Road) for people who walk, bike, ride transit, or drive.
