The 4th Street viaduct project is a bike and pedestrian safety improvement project that includes replacement of the sidewalks and shallow drainage installations beneath the railroad overpass. The project will begin on Monday August 5th and will last 3 to 4 weeks. Temporary traffic control signals will be used to keep one lane open during the project, allowing northbound and southbound movement when signals advise. TARC service will still run this route. Please call 574-5810 if there are any questions.
