The Chesapeake Bay Bridge connects Maryland's Eastern Shore to the western mainland, spanning nearly 5 miles across the bay

The Chesapeake Bay Bridge is a toll bridge that carries US Route 50 across the Chesapeake Bay between Queen Anne's County on Maryland's Eastern Shore and Anne Arundel County on the mainland. The bridge opened in 1952 and remains one of the longest bridge-tunnel systems in the world. If you live in or travel through Maryland, you will almost certainly use it at some point — it is the only direct vehicle crossing of the bay in the state.

The bridge itself is about 4.3 miles long, but the full crossing includes approach roads and a 1.6-mile tunnel section. The entire structure is officially called the William Preston Lane Jr. Memorial Bridge, named after a Maryland governor. Traffic moves in both directions on the same roadway, separated by a movable median barrier that shifts based on traffic flow during rush hours.

Key Takeaways

  • The toll for a standard passenger car is $6.00 when you pay by cash at a toll booth, or $5.50 with a prepaid toll account called E-ZPass.
  • Heavy trucks and vehicles with more than two axles pay higher tolls that vary by axle count, ranging from $10.00 to $30.00 or more.
  • You can pay cash at toll booths, use E-ZPass for faster passage, or set up a toll-by-plate account if you do not have a transponder.
  • The bridge closes to high-profile vehicles (RVs, tractor-trailers, and vehicles towing trailers) when wind speeds exceed 35 miles per hour.
  • Peak traffic occurs during weekday rush hours and summer weekends, so crossing early morning or midday typically means shorter delays.

Current toll rates for different vehicle types

Toll rates depend on your vehicle's axle count and how you pay. A standard passenger car with two axles costs $6.00 if you pay cash at a toll booth. If you have an E-ZPass account — a prepaid electronic toll system — the same trip costs $5.50. E-ZPass is the faster option because you do not stop; the toll is deducted automatically as you pass through a dedicated lane.

Larger vehicles pay more. A vehicle with three axles costs $9.00 by cash or $8.50 with E-ZPass. A four-axle vehicle costs $12.00 by cash or $11.50 with E-ZPass. Five-axle vehicles and larger pay $15.00 by cash or $14.50 with E-ZPass. Vehicles with six or more axles can cost $30.00 or more. These rates explore to tractor-trailers, large RVs, and commercial trucks.

Tolls are collected at the western toll plaza (on the mainland side) as you leave the Eastern Shore heading west, and at the eastern toll plaza as you leave the mainland heading east. You pay once per crossing, not twice.

How to pay: cash, E-ZPass, and toll-by-plate

You have three ways to pay the Chesapeake Bay Bridge toll. The simplest for occasional travelers is cash at a toll booth. Toll booths are staffed during peak hours and have automated payment machines during off-peak times. You hand over cash or insert bills into a machine, and a gate lifts to let you through. This method is slower than electronic options because you must stop.

E-ZPass is a prepaid account linked to a small electronic transponder you mount on your windshield. When you pass through an E-ZPass lane, the toll is deducted automatically from your account balance. You do not stop, and you receive a small discount (50 cents per crossing for a standard car). You can set up an E-ZPass account through the Maryland Transportation Authority website or at certain retail locations. You load money onto the account in advance, and it draws down as you use it.

If you do not have an E-ZPass transponder but want to avoid cash booths, you can use toll-by-plate. This system photographs your license plate as you cross and mails you an invoice. The toll rate is the same as cash ($6.00 for a standard car). This option works if you cross occasionally and do not want to carry cash or set up an account, but invoices can take weeks to arrive, and you cannot dispute charges as easily as with a prepaid account.

When the bridge closes to certain vehicles

The Chesapeake Bay Bridge has strict rules about which vehicles can cross during high winds. The bridge closes to high-profile vehicles — defined as RVs, tractor-trailers, vehicles towing trailers, and any vehicle taller than 13 feet 6 inches — when sustained wind speeds reach 35 miles per hour or gusts exceed 45 miles per hour. These vehicles are at risk of being blown sideways or overturned by strong winds on the open water.

Standard passenger cars and pickup trucks can cross in higher winds. The bridge remains open to all vehicles unless wind speeds are extreme — typically 50 miles per hour sustained or higher. During severe weather, the Maryland Transportation Authority posts closure notices on its website and on digital signs at the toll plazas. If you are driving an RV or towing a trailer, check the weather forecast and the bridge's status before you leave.

The bridge also occasionally closes for maintenance, accidents, or medical emergencies. These closures are usually brief, but traffic can back up significantly. If you see brake lights ahead, be prepared to wait. The bridge has no shoulders or emergency lanes, so disabled vehicles must be towed off by emergency services.

Traffic patterns and the best times to cross

The Chesapeake Bay Bridge experiences predictable traffic surges during weekday rush hours and summer weekends. Westbound traffic (leaving the Eastern Shore) is heaviest on Friday afternoons and evenings as people head to the mainland. Eastbound traffic (heading to the Eastern Shore) peaks on Sunday afternoons and evenings as weekend travelers return home. During these periods, you can wait 30 minutes to an hour or more.

The lightest traffic typically occurs on weekday mornings between 10 a.m. and 2 p.m., and on weekday evenings after 8 p.m. If you have flexibility in your travel time, crossing during these windows will get you across faster. Early morning (before 7 a.m.) can also be light, but rush hour begins around 7 a.m. on weekdays.

Summer weekends are consistently busy because the Eastern Shore is a vacation destination. If you are traveling to or from the shore in July or August, expect delays regardless of the time of day. Winter and spring typically see lighter traffic except during holiday weekends.

Safety rules and what to know about the bridge's design

The Chesapeake Bay Bridge has no shoulders, no emergency lanes, and no place to pull over. If your vehicle breaks down, you must stay inside with your hazard lights on and call 911. Do not attempt to walk across the bridge or flag down other drivers. Emergency responders will locate you and arrange a tow. This is why breakdowns can cause significant delays — the disabled vehicle must be removed before traffic can resume normal flow.

The bridge's movable median barrier shifts during rush hour to accommodate heavier traffic in one direction. During morning rush hour, more lanes point westbound (toward the mainland). During evening rush hour, the barrier shifts to add lanes heading eastbound (toward the Eastern Shore). This system reduces congestion but means you must pay attention to lane markings and signs. Do not cross the median barrier under any circumstances.

Speed limits on the bridge are 55 miles per hour. Speeding is heavily enforced, and the bridge's narrow lanes and lack of shoulders make high speeds dangerous. Sudden weather changes — fog, rain, or wind — can occur quickly over the water, so reduce speed if visibility drops or you feel wind pushing your vehicle.

Frequently Asked Questions

Do I have to pay the toll both ways?

No. You pay once per crossing. If you drive from the mainland to the Eastern Shore, you pay at the eastern toll plaza. If you return to the mainland, you pay again at the western toll plaza. Each direction is a separate crossing and a separate toll.

What happens if I lose my E-ZPass transponder?

Contact the Maryland Transportation Authority to report it lost and request a replacement. You can continue using your account with a new transponder. If you cross without a transponder and your account is active, the toll-by-plate system will photograph your plate and mail you an invoice at the cash rate.

Can motorcycles cross the bridge?

Yes. Motorcycles are charged the standard two-axle toll rate ($6.00 cash or $5.50 with E-ZPass). Motorcycles are not restricted during high winds the way high-profile vehicles are, but wind can still affect handling on the open bridge.

Is there a pedestrian or bicycle path on the bridge?

No. The bridge is for vehicles only. Pedestrians and bicycles are not permitted. If you need to cross the bay without a vehicle, you must use a ferry service or drive around the bay through Virginia.

What if I cannot afford the toll?

There is no toll waiver program for the Chesapeake Bay Bridge. The toll is required for all vehicles. If cost is a barrier, the only alternative is to drive around the bay, which adds several hours to your trip. Some employers or organizations may reimburse toll costs for work-related travel — check with your employer or organization.
