The public gets its yearly chance to cross the Bay Bridge o foot Sunday. The 19th Bay Bridge Walk is to begin at 9 a.m. when Mass Transit Administration buses begin shuttling participants from designated parking lots. The 4.5-mile stroll across the original span of the William Preston Lane Jr. Memorial Bridge coincides with BayFest, a celebration of the Chesapeake Bay that takes place at nearby Sandy Point State Park.
Organizers offer some tips for visitors:
* Travelers from the west should park at either the Navy-Marine Corps Stadium on Rowe Boulevard in Annapolis or at the Anne Arundel Community College in Arnold. Eastern Shore parking will be available at the Chesapeake Bay Business Park in Stevensville. There is no parking available at the bridge or at Sandy Point.
* BayFest runs from 9 a.m. to 4 p.m. Admission is free. The festival features environmental exhibits, crafts and corporate displays. There will be numerous children's activities, a food court and live music.
* Shuttle buses cost $1 round-trip for anyone over age 6. People will be accommodated until the parking lots fill, usually about noon, so it's best to arrive early.
* Drinking water and portable toilets are spaced along the bridge. Bikes, pets, runners and joggers are prohibited. Also, keep in mind it's a bit cooler on the bridge than inland so dress accordingly.
* Since one span is set aside for the walk, motorists should expect heavy traffic on the other. The westbound span will accommodate two-way traffic from 6 a.m. to 6 p.m.
* The walk and BayFest will be canceled in the event of rain or high winds. Radio stations will be advised of the cancellation after 6 a.m. Sunday.
