Bicycles were long prohibited on the bridge, which lacks a safe shoulder. On July 1, 2016, the bridge opened to bicyclists, along with lights to warn drivers about bicycles in the travel lanes. Initially, bicyclists were allowed to use the bridge all week long, with limited hours on weekdays, but since September 6, 2016, bicycle passage has been restricted to weekends, holidays, and other designated dates. Bicycle usage in the first two months was minimal, but Maryland officials said the change was unrelated.
