Work has begun on a $24.5 million project to replace two bridges carrying the ramp from Interstate 84 westbound to Interstate 684 southbound in the Town of Southeast, a project state officials say is meant to enhance safety and modernize one of the Hudson Valley's key highway gateways. The undertaking, known as Ramp G, targets a heavily used stretch of interstate that connects commuters and freight traffic between New York City, Westchester County, and Connecticut.
According to the New York State Department of Transportation, work is now underway on the twin-bridge replacement in Putnam County. New York State Comptroller contract records show NYSDOT awarded the project, contract D265693, to Yonkers-based ECCO III Enterprises Inc., which submitted the winning bid of $24,492,000 during a March 2026 letting that drew five competing contractors, per Open Book New York.
What the Work Involves
Municipal engineering reviews released in March 2026 put the project's anticipated completion date at December 31, 2028, with work spanning deck replacement, superstructure replacement, and roadway widening across both spans, according to documents published by the Town of Southeast. Ramp G carries westbound I-84 traffic over both I-84 and I-684 in the town, making it a structurally critical link rather than a minor connector road.
Federal Highway Administration data pegs average daily traffic on the I-84 corridor near the I-684 interchange at roughly 75,000 vehicles. That volume places the interchange among the busiest junctions in the Hudson Valley, serving as a primary artery between New York City, Westchester County, and Connecticut commuters.
A Freight Corridor, Too
The interchange's importance extends beyond passenger commuting. Per a May 2024 announcement from the New York State Assembly, the junction connects directly to Route 22, a designated New York State Freight Core Highway Network corridor where heavy trucks make up 8 percent of the 20,000 vehicles traveling that route daily. Route 22 provides freight access between Poughkeepsie, Westchester County, and Connecticut via I-84 and I-684. State lawmakers also announced in May 2024 a separate $14.8 million project to repave 12 miles of Route 22 running from the I-84/684 interchange through Southeast, Pawling, and Patterson, underscoring the broader state investment surrounding this junction.
Lessons From Past Bridge Work Nearby
NYSDOT has experience minimizing disruption on this same stretch of interstate. A Federal Highway Administration study documents how the agency previously replaced twin I-84 bridges over Dingle Ridge Road in Southeast back in 2013 using accelerated lateral slide-in technology, limiting the disruption to two 20-hour weekend closures instead of the roughly two years of detours that conventional construction would have required.
More recently, in March 2025, the Connecticut Department of Transportation and NYSDOT jointly announced a project replacing I-684 bridge superstructures over the Byram River between Greenwich, Connecticut, and North Castle, New York, using prefabricated bridge units installed during four weekend closures, according to the Connecticut Department of Transportation. Whether NYSDOT will use similar staged or weekend-closure methods for the Ramp G project has not been detailed publicly.
Why Traffic Management Will Matter
The stakes for managing congestion during construction are high given how quickly incidents at this junction can snarl traffic across state lines. Mid Hudson News reported that a June 2026 collision between two tractor-trailers near the I-84/684 interchange spilled debris across both directions, backing up westbound traffic all the way to the Connecticut border while eastbound traffic stalled back to Route 312. That kind of gridlock illustrates the corridor's vulnerability to even a single serious incident, let alone two and a half years of active construction.
Procurement documents published in February 2026 show NYSDOT required bidding contractors to post a 5 percent bid deposit of roughly $1.5 million and set a 0 percent Disadvantaged Business Enterprise goal for the Ramp G contract, with the award contingent on legislative budget appropriations. The heavy state police presence in the area, patrolled by Troop K, has also made the Town of Southeast Court one of the busiest local traffic courts in New York State, according to legal guides for Putnam County.
Hoodline has previously covered troopers halting a wrong-way DWI run near this same interchange, and reported in April on an overnight chase that ended with a spike-strip takedown at the I-684/I-84 junction. Those incidents, along with a head-on crash in nearby Lake Carmel this month, have kept highway safety in Putnam County in the spotlight even before construction crews moved in on Ramp G.
