So, if a third span across the bay is built, would it become congested during summers? Probably at some point, but whether a third span is built or not, tolls could vary to ration traffic better than waiting in long backups does. The Maryland Transportation Authority suggests motorists cross the bridges during off-peak times; tolls varying by time of day would actually prompt them to do so, and could be implemented soon. Also, Eastern Shore vacation home owners and management companies may learn to offer incentives, such as reduced rental fees for late evening and early morning arrivals and departures. Businesses could vary their employees’ work hours. Such incentives would further spread the peak travel times and reduce peak traffic.
