Severe Thunderstorm Threat Prompts Weather Advisories for Maryland Toll Facilities

The Maryland Transportation Authority (MDTA) has issued advisories to the public regarding potential severe weather conditions that could impact travel on its toll facilities, particularly the Bay Bridge. Residents are urged to exercise caution and stay informed about rapidly changing driving conditions that may arise from severe thunderstorms, heavy rains, lightning, and powerful winds.

The approaching weather system carries the possibility of strong thunderstorms, which can lead to hazardous conditions on roadways. These conditions may include standing water, downed trees, and debris, all of which can pose significant risks to drivers. The MDTA strongly advises against attempting to drive through flooded roadways, emphasizing that the depth of the water and the stability of the road beneath cannot be accurately assessed. The “Turn Around, Don’t Drown” campaign highlights the dangers of floodwaters and encourages motorists to seek alternate routes rather than risk driving through them.

Specific attention is being given to the Bay Bridge, where the MDTA anticipates potential eastbound delays during the afternoon and evening rush hour periods due to adverse weather. The ability to implement two-way operations, which allows for one lane of eastbound traffic to be directed onto the westbound span, may be hindered by precipitation and wind warnings or restrictions. Consequently, drivers using the Bay Bridge should be prepared for the possibility of extended travel times and potential disruptions.

The MDTA has outlined a tiered system of wind warnings and restrictions that will be enforced on all its bridges based on real-time weather conditions, not forecasts. These measures are designed to ensure the safety of all travelers. When sustained winds reach 30-39 mph or gusts persistently exceed 30 mph, a Wind Warning will be issued. During this phase, operators of house trailers, box trailers, motorcycles, vehicles with roof-mounted cargo, and other vehicles susceptible to high winds are advised to proceed with caution.

As wind speeds increase, stricter measures will be put in place. Limited Wind Restrictions will be enacted if sustained winds reach 40-49 mph or gusts persistently exceed 40 mph. At this level, vehicles such as house trailers and empty box trailers, along with any vehicle deemed unsafe by law enforcement, will be prohibited from crossing. Motorists denied passage will be assisted in safely turning around.

Further escalation to Full Wind Restrictions will occur if sustained winds exceed 50 mph or gusts persistently exceed 50 mph. Under these conditions, only automobiles, pickup trucks, flatbed trailers, commercial buses, and heavy-laden tractor-trailers (with a gross weight of at least 64,000 pounds for tractor-box trailer combinations) will be permitted to traverse the bridges.

In the most extreme weather scenarios, when sustained winds exceed 55 mph or gusts persistently exceed 55 mph, Traffic Holds and Bridge Closures may be implemented. This decision will be made by the MDTA if sudden increases in wind speed or gusts jeopardize life or property, leading to the suspension of all traffic movement across the bridge.

It is crucial for travelers to understand that decisions regarding these restrictions are based on immediate weather conditions at the toll facilities, not on weather forecasts. Motorists are encouraged to monitor weather reports throughout the day and to be aware that conditions may differ significantly on their return journeys. For 24/7 updates on conditions at the Bay Bridge, the public can call 1-877-BAYSPAN (1-877-229-7726).
