4th Avenue Underpass
Fourth Avenue Underpass Re-Construction
Downtown Tucson will soon have a new eastside ‘gateway’ – an attractive and easy entry to our rapidly progressing city center.
Reconstruction of the Fourth Avenue Underpass has begun and is scheduled to be completed in the fall of 2008.
The new underpass will provide for one lane in each direction carrying vehicle and streetcar traffic, separate bicycle lanes and two pedestrian ways accessible for persons with disabilities.
The lighted pedestrian walkways, 20 feet wide on the east side and 10 feet wide on the west, will provide safe and convenient access between the Fourth Avenue shopping and entertainment district and the Congress Street Entertainment District and the rest of Downtown. An elevated walkway will provide convenient pedestrian access from the Historic Depot to the public plaza development planned for the area surrounding the intersection of Congress Street and Fourth Avenue.
Be Prepared for Construction – Drive Smart; Drive Safe
The reconstruction of the Fourth Avenue Underpass will make some traffic detours necessary and will slow traffic both east and west bound on Broadway Boulevard in the Downtown area. Portions of Toole Avenue on the east end of Downtown will be restricted.
Access to all area businesses will be maintained during the project and directional signs will be placed to help patrons reach them easily.
Traffic impact alerts will be communicated to the public using local media, website and the information line at 792-4AVE (4283). If you would like to receive electronic updates, please call the information line at 792-4AVE (4283) and provide staff with your email information.
Motorists and bicyclists should pay close attention to construction and detour signage and watch for construction equipment operating in the area.
The Tucson Department of Transportation asks that all motorists and bicyclists traveling in the area, pay close attention to construction and detour signage, watch for construction equipment and proceed with caution, drive safely, and obey the speed limit.
Park at The Pennington Street Garage
