Commuters will soon pay a little more at the tolls to use the E-470 tollway  that runs from Parker to Broomfield.

The E-470 Public Highway Authority board of directors unanimously approved the implementation of a new rate schedule that will raise all tolls on the 47-mile stretch of highway by about 4 to 5 percent.

License plate toll customers with two-axle vehicles passing through mainline toll plaza A, between Peoria Street and Chambers Road in Douglas County, will pay $2.95, a 15 cent increase, while EXpressToll customers will pay $2.35, a 10-cent increase.

Two-axle vehicles commuters passing through the remaining four mainline toll plazas (B through E) will pay an additional 10 cents, resulting in a $3.25 charge for license plate toll customers and $2.60 charge for EXpressToll customers.

Ramp tolls for two axle-vehicles will also increase by 5 cents, resulting in a $1.30 charge for license plate toll drivers and $1.05 charge for EXpressToll customers.

These new tolls will be effective on Jan. 1. Vehicles with three-axles or more pay an additional toll rate per axle.

EXpressToll customers will continue to pay about 20 percent less than license plate toll customers. License plate toll customers can pay the lower rate by opening an EXpressToll account at www.expresstoll.com.

E-470 finance director Stan Koniz said the increase will generate an estimated $124.8 million in revenue from toll operations — a projected $8.9 million revenue increase from this year.

E-470 spokesman Dan Christopherson said the increases allow the board to cover operational costs and meet its debt service obligations to bondholders, an expenditure that will increase next year from $67.4 million to $74.9 million.

He said E-470’s toll rates are a part of a finance plan approved by the E-470 Public Highway Authority in 1995.

The board voted in 2010 to replace larger rate increases every three years with smaller, incremental annual rate increases that would alleviate the impact on customers’ commuting expense over time.
