Nearby weather observations do not determine bridge restrictions. MDTA uses conditions on the bridge; a single gust here cannot confirm a restriction.
See traffic cameras →Maryland’s four wind stages
These are MDTA’s policy thresholds, not a reading of the current restriction. Sustained winds must persist for at least 10 continuous minutes; gusts must persistently exceed the listed threshold over 15 minutes.
Wind warning
30–39 mph
Sustained wind
Use caution with trailers, motorcycles, loaded roof racks, and other wind-sensitive vehicles.
Or: gusts persistently above 30 mph.
Limited restrictions
40–49 mph
Sustained wind
House trailers and empty box trailers are prohibited. Police may turn away other vehicles that cannot cross safely.
Or: gusts persistently above 40 mph.
Full restrictions
Above 50 mph
Sustained wind
Only cars, pickups, flatbed trailers, commercial buses, and heavily loaded tractor-trailers may cross. Tractor-box trailer combinations must have a gross weight of at least 64,000 lb.
Or: gusts persistently above 50 mph.
Traffic holds / closure
Above 55 mph
Sustained wind
MDTA may stop all traffic. Sudden dangerous winds can also trigger a hold.
Or: gusts persistently above 55 mph.
Two-way (contraflow) operations put opposing directions on the same span. MDTA prohibits that lane arrangement during wind warnings/restrictions, fog, or precipitation; this does not by itself mean the whole bridge is closed. Source: MDTA wind policy. Reviewed September 7, 2026.
Traveling with an RV or trailer?
Do not infer permission from a low wind reading on a weather app. Check the active MDTA restriction and call BaySpan before approaching. Follow police directions if your vehicle is turned away.
