For the safety of the public, the road and trail must be clear of vehicle, bicycle, and pedestrian traffic through the work zone as these operations occur. The restrictions may be lifted earlier if the work is completed sooner.

As a reminder, starting at approximately 7:00 AM on Monday, June 29, Commercial Street/Forward Avenue and Nine Mile Run Trail will close to traffic continuously around-the-clock through early August for the official demolition of the existing bridge followed by the slide and alignment of the new bridge.
