Project Background

In June 2021, the City of Centennial adopted the Colorado Boulevard Multimodal Corridor Study to improve safety and accessibility for all types of transportation along Colorado Boulevard between Orchard Road and County Line Road.

Following the study’s adoption, the City applied for federal funding to construct the 1-mile stretch between Arapahoe Road and Dry Creek Road, as the first major implementation of a multi-phased approach to enhance the full corridor. In 2023, the City was awarded a 2024-27 DRCOG Transportation Improvement Program (TIP) grant of up to $9.4 million for construction, with 90% ($8.41 million) covered by federal and state funds and a 10% match ($950,000) required by the City.

This project is currently in the design phase, following the 2021 Corridor Study’s recommendation to reduce this portion of Colorado Boulevard to one lane in each direction with a center turn lane. The remaining roadway space will be repurposed for multi-use paths.
