I-84 Roadwork Planned Across 4 CT Towns, Ramp Closures Possible

DANBURY, CT — Drivers traveling along Interstate 84 through Greater Danbury could encounter ramp closures and detours next year as the Connecticut Department of Transportation prepares for a pavement preservation project spanning four towns.

The project will involve work on I-84 in both directions through Danbury, Bethel, Brookfield and Newtown, with construction expected to begin in spring 2027, according to CTDOT.

Transportation officials plan to apply an ultra-thin bonded overlay to the highway's pavement, a treatment intended to extend the roadway's lifespan and improve its overall condition.

The work will cover approximately seven miles in each direction, with the following sections scheduled for improvements:

• I-84 eastbound: From the approach to the bridge over the Still River in Danbury, near mile marker 8.09, through Bethel and Brookfield to the Route 6 junction in Newtown, near mile marker 15.27.
• I-84 westbound: From the approach to the Church Hill Road overpass in Newtown, near mile marker 15.14, through Brookfield and Bethel to just beyond the Still River bridge in Danbury, near mile marker 8.10.

The project will also include pavement treatments on entrance and exit ramps along the affected stretch of highway.

CTDOT said short-term, off-peak detours may be implemented if ramps need to close during construction. Specific closure dates and detour routes have not yet been announced.

The pavement preservation work is part of CTDOT's broader effort to maintain Connecticut's transportation infrastructure and extend the useful life of existing roadways.

Design work is expected to be completed in October 2026, with construction tentatively scheduled to begin in spring 2027, pending funding, project approval and any necessary permits.

The project will be funded entirely with state money, according to CTDOT.

Transportation officials said a public information meeting will not be held because the work is considered routine maintenance. However, residents can submit questions or comments as the project moves forward.
