High Line Canal Trail Underpass at Colfax
Arapahoe County (Open Spaces) is planning improvements to the High Line Canal Trail that include design work for an underpass at Colfax Avenue. Regional project tracking (DRCOG) lists the Colfax underpass (RFP 2024-013) as a design-firm selection RFP that was “being drafted,” indicating no buyer-hosted solicitation was available in the captured sources. A separate Arapahoe County solicitation for a Highline Canal underpass at Broadway was posted on third-party procurement portals and closed in early 2025, so no open buyer-hosted Colfax solicitation could be found from the provided aggregator link.
