The list of to-dos at the Route 35 bridge construction site is long, but the days of Ridgefield residents being irritated by the project are lessening.

That was the news from the state’s Department of Transportation office this week.

Charles Murad, the bridge project engineer, told The Press that the job “should be complete by the end of May.”

What has to happen between then and now?

“We have sidewalk, curbing, line striping, topsoil, seeding, removal of sheeting, removal of water handling pipe, plantings, semi-final inspection, final inspection, punch list, and demobilization to complete,” Murad said.

The contractor, Bloomfield-based Baier Construction, returned to the site this week to start the work.

Murad emphasized that the work schedule is weather-dependent, signaling that snowstorms could delay completion.

“We will have a discussion with the contractor and request that he does what he can to clean up the area, but it is not our practice to direct the contractor’s activities,” Murad said, following a complaint by Selectman Bob Hebert in February about the site’s aesthetics.

The engineer added that, in addition to Baier, Eversource and Frontier both have equipment on the site that needs to be moved.
