Mass DOT says the trees are dangerous in the event a vehicle ends up in the median.
“If somebody were to lose control of their vehicle, they could pull over and be out of the travel way, or if they were to lose control they would also have some space to recover control,” said Mass DOT spokesman Michael Verseckes, adding that the trees also could be hazardous during a winter storm.
The tree clearing is a part of a series of improvements being made to the roadway.
“The cutting is actually a part of a bigger project to resurface Route 6 for about eight miles beginning at the canal, or towards the Sagamore Bridge, and heading east to the town line of Sandwich and Barnstable,” Verseckes said.
Officials hope to have the project completed by mid-November.
