Project Description:

The Downtown Intermodal Center (DIMC) Pedestrian Safety and Bus Access Improvements project was undertaken by the City of Tucson Department of Transportation (TDOT) to improve bus access to the Ronstadt Transit Center (RTC) and to improve pedestrian facilities such as sidewalks and curb access ramps within the immediate area around the transit center to make them compliant with current Americans with Disabilities Act (ADA) guidelines.  

The project consists of the following design elements:

  • Realignment of Pennington Street to Toole Avenue for improved bus access from the north to the RTC.
  • Permanent conversion of 6th Avenue from one-way northbound to two-way operation from 7th Street south to Broadway Boulevard.
  • Upgraded traffic signals at the 6th Avenue/Toole Avenue/Alameda Street and 6th Avenue/Pennington Street intersections.
  • Modifications to new traffic signals at 6th Avenue/Congress Street and 6th Avenue/Broadway Boulevard.
  • Pavement rehabilitation of 6th Avenue.
  • Replacement of deficient curb access ramps at each project intersection.
  • Replacement of sidewalk sections that are not in compliance with current ADA guidelines

Project implemenation will occur in two phases. Phase 1 will consist of the permanent conversion of 6th Avenue from one-way to two-way traffic operations. This includes new signals at the 6th Avenue/Toole Avenue and 6th Avenue/Pennington Street Intersections. 6th Avenue will also receive a 2" mill and overlay between Toole Avenue and Congress Street and a microsurface treatment between Congrees Street and Broadway Boulevard. Phase 2 will include the realignment of Pennington Street to Toole Avenue with a new traffic signal, improved pedestrian access and landscaping. Please reference the project documents for more detailed information.
