Following complaints about the condition of local roads during the natural gas installation, town officials said Tuesday that a new contractor has be hired to start this week. The utility company overseeing the project is “very much aware of our dissatisfaction,” according to Public Works Director Tiger Mann. “The present contractor [Ferreira] is being asked to vacate the premises, and the new contractor will commence on the main installation services and restoration next week,” Mann said during a regular Board of Selectmen meeting, held at Town Hall. Since Ferreira, a contractor for Eversource, began patching New Canaan roads in the wake of the gas main installation, residents have been complaining about the quality of the repairs. Stratford-based Burns Construction will take over the job starting Wednesday, Mann said.
