A stretch of the asphalt “settled pretty badly” last week leading to worries that a sinkhole might be about to open up, said Highway Surveyor Chris Gonslaves.
Crews dug up the road in search of the cause and found that a 12-inch drainage pipe had broken, saturating the ground with rainwater runoff.
Mr. Gonsalves said that the pipe was resting on ledge and may have fractured due to pressure caused by ground heaving and movement.
They’ve filled it back in for the time being and blocked off the damaged area until a contractor can be hired to repair the pipe and road.
“In the meantime, the road remains passable,” if somewhat restricted, Mr. Gonsalves said.
He said that the town hopes to obtain state Chapter 90 funding to pay for much of this repair along with paving work at Beach Avenue and East Beach Road under a single contract.
Riverview Avenue is a small road that leads from Pine Hill Road to the East Branch of the Westport River (about midway between the Head and Hix Bridge).
