The eighth annual Bay Bridge Day walk will be held April 18, when the eastern span of the bridge will be closed to traffic and open to pedestrians for a 4.3-mile walk across the Chesapeake Bay.

The parallel span of the Bay Bridge will carry two-way vehicular traffic during the walk, according to a Maryland Toll Facilities Administration spokesman.

No public parking facilities will be available at either the bridge or Sandy Point State Park. Parking for those taking part in the free walk will be available at the Navy-Marine Corps Stadium in Annapolis and at Anne Arundel Community College, on College Parkway off Maryland Rte. 2 in Arnold.

Free round-trip shuttle bus service from the parking areas will begin at 9 a.m., with the last buses leaving for the bridge at 3 p.m. Walkers must be off the span by 5 p.m.

Parking may be cut off early because of crowds or weather, a Toll Facilities spokesman said. Last year, because of the large turnout, the parking lots were closed in the early afternoon. If the walk is cancelled because of heavy rain or high winds, the public will be notified by local radio broadcasts.

Jogging and running will be prohibited on the bridge and no pets, bicycles, skateboards or food will be allowed on the span during the walk. Children under 16 must be accompanied by adults, with at least one adult for every five children.
