Correction: An earlier version of this article incorrectly referred to new E-ZPass toll rates in Maryland. These are the E-ZPass commuter rates, not rates for all E-ZPass users. The commuter rates will increase to $2.10 on the Bay Bridge and the Nice Bridge; $1.40 for the Key Bridge and the two Baltimore tunnels, and $2.80 for I-95 between Baltimore and Delaware and the Hatem Bridge. Drivers with a Maryland E-ZPass but no commuter plan receive a small discount on the cash rate.

It’s going to cost more to cross the Baltimore Harbor and travel on the Chesapeake Bay Bridge beginning next week. Tolls are set to increase Monday on several of Maryland’s bridges, tunnels and highways.

For passengers paying cash, rates will rise to $4 from $3 for passenger vehicles using the Fort McHenry Tunnel, the Baltimore Harbor Tunnel or the Francis Scott Key Bridge.

On the Bay Bridge, it will cost $6 per passenger vehicle, an increase of $2. It will also cost $6 to cross the Nice Bridge in southern Maryland, which carries Route 301 over the Potomac River.

Tolls on Interstate 95 between Baltimore and Delaware will go up to $8 from $6, as will tolls for driving on the Hatem Bridge over the Susquehanna River.

For drivers using E-ZPass transponders, the tolls are also going up. The E-ZPass rate for driving across the Bay Bridge and the Nice Bridge will now be $2.10, while it will go up to $1.40 for the Key Bridge and the two Baltimore tunnels. The E-ZPass rate will increase to $2.80 for E-ZPass commuters on the northern stretch of I-95 and the Hatem Bridge.

Tolls will not increase on the Intercounty Connector, but on the other roads, video tolls — which are issued to drivers who don’t pay cash and don’t have an E-ZPass — are increasing.

The Maryland Transportation Authority said the higher tolls are needed to help pay for construction projects and preservation work.

“There’s never a good time to raise tolls,” said Kelly Melhem, a spokeswoman for the authority. But she said the increase is necessary. “It is there to fund needed work to keep our tunnels, bridges and roadways safe and maintained.”

Higher tolls were approved in September 2011, with the first increases arriving in November of that year.

The toll hikes also coincide with the arrival of higher gas prices in Maryland following a gas-tax increase approved by lawmakers this year.
