Such lanes have opened recently in Los Angeles and on the Capital Beltway in Virginia.
Corcoran cited the Beltway as an example of a similar project; he was part of a group that considered bidding on the work.
In Massachusetts, his proposal is unsolicited. The state would have to conduct a competitive bid process. An early, unsolicited proposal can sometimes have the upper hand, though, because it “sets the bar” for other bids, he said.
In addition to the new lanes, the Corcoran group pledged to reconstruct 15 bridges and incorporate planned improvements to some Route 3 interchanges.
Corcoran said he believes the state does not oppose the idea but is trying to gauge public opinion.
“People are trying not to be out front on it,” he said.
Decades ago, the state looked at expanding capacity on Route 3, but set the issue aside because there was no money for it, he said.
“This project pays for itself,” Corcoran said. “Many other projects don’t.”
