Brookfield Officials Highlight I-84 Flex Lane Project Ahead Of Planned 2027 Construction

BROOKFIELD, CT — State transportation officials are advancing plans to add a reversible “flex lane” to Interstate 84 between Exits 3 and 7 in Danbury, a project intended to reduce congestion during peak travel hours and improve regional traffic flow, according to a fact sheet released by the Connecticut Department of Transportation.

The proposal would repurpose the existing median-side shoulder into a temporary travel lane that would open only during periods of heavy congestion, typically weekday morning and afternoon rush hours in the direction with the greatest traffic demand. Trucks would be prohibited from using the lane.

Local officials, including representatives from Brookfield, have been involved in shaping the project through the state’s I-84 Danbury Project Advisory Committee.

“A couple of us here in Brookfield have been on the I-84 Danbury Project Advisory Committee for a few years and have been participating in CTDOT’s development of concepts to reduce congestion on I-84 in our area,” Brookfield Economic Development Specialist Greg Dembowski said in a statement. “The plan to construct flex lanes between Exits 3 and 7 is taking shape with construction planned for 2027.”

According to CTDOT, overhead electronic signs would signal when the flex lane is open, closing soon, or closed. When open, drivers would be able to enter or exit the lane freely, with the lane separated from adjacent traffic by a solid yellow line. The lane would remain closed during off-peak hours.

State officials say the flex lane is designed to smooth traffic flow and reduce sudden slowdowns that can contribute to crashes. By keeping more drivers on the interstate, the project is also expected to reduce cut-through traffic on local roads, potentially improving safety for motorists, pedestrians, cyclists and transit riders.

The fact sheet notes that similar flex lane systems in Michigan, Ohio and Wisconsin have improved traffic flow, commute times and roadway safety. CTDOT officials say the I-84 project would be Connecticut’s first use of the approach.

Because the work would stay within the existing I-84 roadway footprint, construction is expected to move more quickly than traditional widening projects, limiting disruptions and reducing the need for extended lane closures, according to the agency.

Brookfield officials say public outreach will be a key part of the process as the project moves closer to construction.

“Since this would be the first of its kind in Connecticut, there is a plan to educate the public and increase community engagement,” Dembowski said. “I have invited the DOT project team to reserve a tent to present this project at our annual Block Party, which this year will be on Sunday, June 7.”

CTDOT officials say improving traffic reliability on I-84 would also support local businesses by reducing travel time and transportation costs, while cutting vehicle emissions through reduced idling and congestion.
