Alameda Ave Underpass Rehabilitation

Project Overview

The W Alameda Ave Underpass pedestrian pathway between Cherokee St and S Santa Fe Drive provides a vital mobility link for Denver residents to retail stores, light rail, recreational and commercial destinations on each side of the railroad corridor. Currently, this site presents several functional and experiential deficiencies in the concrete retaining walls that DOTI identified for improvements in the 2019 Connect Alameda Feasibility Study. Foremost among these issues is the narrow width of the pedestrian/cyclist pathway, the noise and proximity of passing vehicles, and the condition of the existing retaining walls, which exhibit crumbling, cracking, and spalling concrete from overhead that presents safety hazards to both adjacent vehicular and pedestrian traffic.

Ultimate Improvements

The ultimate improvements require reconstruction of the retaining walls and replacement of the railroad bridge structures to widen the corridor, which is part of the city's long-term planning.

Interim Improvements

Until the ultimate improvements can take place, the intermit solution will address safety hazards and improve the visual and contextual experience for all users. The project, funded by the 2017 voter-approved Elevate Denver GO Bond, which allocated $7 million for the project, will stabilize the structure and make ADA improvements. The project will include a new grade-separated, ADA-compliant sidewalk/multiuse path along the north side of Alameda. The project will also stabilize deteriorating wall sections.

Traffic Impacts

• Working Hours:
  • Monday through Friday, 7:00 a.m. - 5:00 p.m.
  • Minimal night work may be required but will adhere to all noise ordinance requirements
  • Minimal daytime weekend work may be required throughout the project
• Lane Closures:
  • Both direction of traffic will be reduced to single lanes through the work zone.
  • During the first phase of work, there will be a 24/7 closure of the westbound lanes and westbound traffic will be shifted to the left eastbound lane.
  • Once this phase is complete, all traffic will be moved to the westbound lanes and eastbound traffic will be shifted to the left westbound lane.
  • There will be potential full closures of the underpass with a detour in place for approximately 24 hours each, likely no more than two times throughout the course of the project.
  • Pedestrian traffic will not encounter any significant impacts or detours throughout the course of the project.
