Arapahoe Avenue Reconstruction (15th to Broadway)

The Arapahoe Avenue Reconstruction Project provided much-needed maintenance and improvements to bike, pedestrian and car travel to increase safety and comfort and preserve this important thoroughfare. The project also included improvements to water utilities. The underpass at Arapahoe Avenue and 13th Street was also reconstructed to provide a safer, more accessible and less flood-prone underpass along the Boulder Creek Path.

Thank you for your patience during this project. For additional information about this project and other construction projects in the city, check out Cone Zones.

Construction Impacts 13th Street north of Arapahoe is currently closed, with access to 13th Street businesses off of 14th Street. The underpass near 13th and Arapahoe is closed with a detour to an on-street crossing near 13th St. to access the Boulder Creek Path.

Multiuse Path Detours

Central Park Impacts

Some of the final landscape restoration is taking place in Central Park. These areas are marked off, and there are detours for pedestrians and cyclists.

Project Details

This is a major project that includes several components:

  • Street, path and sidewalk reconstruction from 15th Street to Broadway to replace aging asphalt with concrete and improve multimodal facilities and drainage. Street reconstruction is substantially completed as of Aug. 14, 2018. Path and sidewalk reconstruction will continue.
  • Replacement of a storm sewer box culvert under 13th Street and the Smith-Goss irrigation ditch pipe along the south side of Arapahoe Avenue, both of which are in deteriorated condition.
  • Reconstruction of the bicycle and pedestrian underpass at 13th Street to improve line of sight, reduce flooding and bring it up to accessibility and city standards.
  • Removal of 50 trees to allow for the utility and underpass work. New trees will be planted to replace those removed for the construction projects and additional landscaping will be completed near the adjacent areas.

Funding

$2.7 million in city transportation funds has been provided to complete this phase of the Arapahoe Avenue street reconstruction between 15th Street and Broadway. The completed phases of this project were funded by the 2011 voter-approved Capital Improvement Bond

Funding for the new underpass at Arapahoe Avenue and 13th Street is provided in part by the 2014 Community, Culture and Safety Tax.
