Between the rising gas costs and an increase in tolls, it's going to cost you more to drive to Allentown starting Sunday.

The Pennsylvania Turnpike Commission said toll rates will increase Jan. 5 by 12 percent for cash customers and two percent for E-ZPass customers.

The toll cost from Mahoning Valley to Lehigh Valley is increasing from $2.30 to $2.60 one way.

E-ZPass customers, who today see about a 25-percent savings on tolls, will save at least 35 percent compared to cash. The cost from Mahoning to the Lehigh Valley is increasing from $1.69 to $1.72.

Today, more than 70 percent of Pennsylvania Turnpike travelers use E-ZPass.

Many customers get E-ZPass online at www.paturnpike.com or by calling 1-877-PENN-PASS (1-877-736-6727). Customers can also buy an E-ZPass GoPak at more than 300 retailers across the state.

It costs $38 to purchase an E-ZPass if using a credit or debit card to set up an auto-replenishment account; the cost includes a $35 toll balance plus a $3 annual fee. In addition, E-ZPass retailers charge a one-time convenience fee (there is no convenience fee for those who join online or by phone).

The turnpike commission says new revenues are necessary to continue to effectively and efficiently maintain and operate the 550-mile turnpike system; remain focused on efforts to expand, modernize and widen the turnpike, parts of which are nearly 75 years old; and supply needed funding to the Pennsylvania Department of Transportation for investment in off-turnpike road and bridge improvements as well as in public transit.
