A movable safety tunnel rides on parapets within a bridge. The safety tunnel is locked in place in a respective section of the bridge while maintenance or other operations are performed on that section of the bridge. This allows the traffic to flow through the safety tunnel and along the bridge, and the safety tunnel shields the traffic from any dust or debris. When the maintenance on that respective section of the bridge has been completed, the safety tunnel is unlocked and pushed (and/or pulled) by suitable equipment to the next adjacent section of the bridge; and the safety tunnel is again locked in place as the maintenance is performed. This procedure continues, progressively, along the bridge. In one embodiment, the safety tunnel has a trolley system riding on respective rails constructed on top of the parapets.
