Massachusetts Turnpike Authority Chairman Matthew Amorello has resigned his post (effective Aug. 15), following repeated calls for his removal from Massachusetts Gov. Mitt Romney after last month’s fatal accident in the Big Dig’s I-90 connector tunnel.

Oversight of the massive project and the ongoing inspections to prevent more failures has been handed over to the state Department of Transportation.

CNN reported that under his contract, Amorello will continue to receive his salary ($223,000 per year) through Feb. 15, 2007.
