For almost the next year, a stretch of the Merritt Parkway in Greenwich will have a new concrete barrier and construction vehicles entering and leaving at any time.
There will be some lane closures overnight on the northbound-traffic side of the highway, between 9 p.m. and 6 a.m. The project isn’t scheduled to be completed until Nov. 27, 2018.
The purpose of the project is to install a new drainage pipe under the Merritt to increase the flow capacity of Horseneck Brook to the Putnam Lake reservoir. The construction will take place between Interchanges 29 and 31.
The pipe will be “pipe jacked” — essentially, pushed into position — under the roadway, according to the Connecticut Department of Transportation, which announced the project.
The contract, for almost $3.9 million, was awarded on Aug. 14 to New England Infrastructure Inc.
On weeknights, the company isn’t allowed to close lanes except between 9 p.m. and 6 a.m.. “Allowable lane closures are extended on weekends,” according to ConnDOT.
