This study focused on identifying and prioritizing a set of project improvements to prepare for short-range and long-range improvements as future funding sources are identified. To address the safety of all users equitably, the project team gathered input from residents, businesses, and institutions along 88th Avenue throughout public engagement events on how to improve bicycle and pedestrian safety, improvements to transit access, speed, reliability, and capacity needed for vehicular traffic. The study was funded through a Transportation Improvement Program grant administered by the Denver Regional Council of Governments (TIP ID 2022-024).
