The state Department of Transportation says it could cost up to $250 million to put a multi-use trail along the side of the Merritt Parkway between Stratford and Greenwich.
Advocates have promoted the trail as an important piece of the East Coast Greenway, a 2,750-mile network of trails from Maine to Florida.
Michael Calabrese, the project manager for the DOT, told The Connecticut Post that a large stretch of the path would have to be boardwalks to protect wetlands.
Opponents said the 14-foot wide path also would be bad for the environment, requiring the use of asphalt and the removal of hundreds or even thousands of trees.
One in a series of public meetings to discuss the trail will be held at 7 p.m. on Wednesday in New Canaan.
Wednesday, April 30, at the Outback Teen Center, 71 Main Street, in New Canaan. The presentation will be at 7 p.m.
Thursday, May 15, in the Trumbull Library Community Room at 33 Quality Street, Trumbull. The presentation starts at 7 p.m.
