Massachusetts governor signs transportation reform bill

The new law eliminates the Massachusetts Turnpike Authority, but leaves intact the Massachusetts Port Authority and Massachusetts Bay Transportation Authority.

Nearly all other state transportation functions would be consolidated under a new Massachusetts Department of Transportation.

Patrick said the law will put an end to what he called "the Big Dig culture of deception, patronage and waste," referring to the nearly $15 billion highway project which was plagued by cost overruns, falling debris and leaks.

"Today, we are inaugurating a new era of streamlined and efficient delivery of transportation services to the residents of Massachusetts," said Patrick, who signed the bill in his Springfield office.

By agreeing to the bill, Patrick has also committed to approving a 25 percent increase in the state sales tax, a portion of which will go to help eliminate a proposed July 1 toll hike.
