NORWALK — A 104-year-old, family-run construction company that built the Merritt Parkway and countless other projects in the city and state will close.

Despite some mixed feelings, owners Mike and Dan Deering have decided to shut down the Deering Construction company, a family-run business that's spanned five generations.

"This wasn't something that was planned, it's bittersweet, but it's the right time for us," Mike Deering said. "We're at that retirement age now, we talked about it and it's a good time for us to step away."

Mike Deering is 60 and his brother Dan is 65.

The company plans to auction off everything — from outdoor heavy machinery to office desks and chairs.

Deering Construction was started by their great grandfather Dan Deering in 1919. The company has provided construction services in greater Fairfield County and throughout Connecticut. Its services include heavy civil construction, excavation and grading, storm drainage, sewer, utility, streetscape construction and Bituminous Concrete paving.

The construction of the Merritt Parkway, one of the company's first projects, and the Route 7 Connector were two of the biggest projects for the company. There are three final projects to be completed, including the Norwalk River Valley Trail. Mike Deering said the company will completely shut down when the last three projects are done at an unspecified date.

"It's been a great experience for the five generations of our family," Mike Deering said. "Thanks to everyone who used our services over the years."
