Two top-ranked Senate leaders and other North Shore officials are boycotting a hearing Monday on a proposed toll hike on the Tobin Bridge – accusing Massport of refusing to consider other options.

Massport is on the hook for $365 million to pay for the infamous Big Dig overruns, and is looking to raise part of the cash by hiking the $2 Tobin inbound toll to $3 next spring.

Senate Majority Leader Frederick E. Berry and Senate Criminal Justice Chairman Thomas M. McGee say it’s not fair for Massport to put its burden on a single geographic group.

“It’s taxation without representation,” said Berry (D-Peabody). “Why should we participate in this charade when it’s a fait accompli?”

After the last Tobin toll hike on Jan. 1, 2002, state lawmakers tried to ward off further levy increases by requiring Massport to study other options and report back by Dec. 31, 2003.

Massport spokesman Jose Juves admitted the agency is leaning heavily toward the Tobin toll hike, but insisted it has considered “many options,” including increases in airport fees.

North Shore lawmakers are pushing for an increase in the gas tax, or installing new tolls on Interstate 93 or Route 3.
